feat(evals): Dataset v1.4 - Add tool context to judge prompt and improve evaluation accuracy

This commit implements comprehensive improvements to the MCP tool selection evaluation system (v1.4),
focusing on adding complete tool descriptions to the judge prompt, clarifying tool intent, implementing
bidirectional tool equivalence, and fixing test case quality issues.

Comparing baseline (v1.4 experiments apify#1-apify#4) vs current (v1.4 experiments apify#5-apify#8):

- GPT-4o Mini: 99% → **97%** (-2%) - Minor regression
- Claude Haiku 4.5: 95% → **99%** (+4%)
- Gemini 2.5 Flash: 91% → **96%** (+5%)
- GPT-5: 91% → **99%** (+8%)

- GPT-4o Mini: 93% → **97%** (+4%)
- Claude Haiku 4.5: 91% → **95%** (+4%)
- Gemini 2.5 Flash: 89% → **97%** (+8%)
- GPT-5: 88% → **99%** (+11%) ← Largest improvement

**All models now significantly exceed the 70% threshold with more consistent performance.**

**Key Insight:** Adding complete tool descriptions to the judge prompt eliminated false negatives
and improved judge accuracy significantly, especially for GPT-5 (+11%) and Gemini (+8%).

**Before:** Judge prompt had NO tool descriptions at all. The judge was evaluating tool selections
without understanding what each tool does, leading to arbitrary penalization.

**After:** Added comprehensive "Important Tool Context" section with descriptions for ALL tools:

**Tool descriptions added:**
- **search-actors:** Searches Apify Store to find scraping tools/Actors (NOT celebrity actors). Emphasizes informational intent.
- **apify-slash-rag-web-browser:** Browses web to get data immediately (one-time data retrieval). Emphasizes time indicators.
- **call-actor:** Mandatory two-step workflow (step="info" then step="call"). Explains info step is CORRECT and required.
- **fetch-actor-details:** Gets Actor documentation without running it. Notes overlap with call-actor step="info".
- **search-apify-docs:** Searches Apify documentation for platform/feature info.
- **get-actor-output:** Retrieves output data from completed Actor runs using datasetId.
- **fetch-apify-docs:** Fetches full content of specific Apify docs page by URL.

**Keyword Length Guidelines** section added to prevent judge from penalizing thoughtful keyword additions.

**Impact:** Judge now understands tool purposes and correctly evaluates tool selections instead of
arbitrary penalization. This was the PRIMARY cause of LLM-judge improvements (+4% to +11%).

**Before:** No tool normalization existed - direct string comparison only.

**After:** Bidirectional normalization treats `call-actor(step="info")` and `fetch-actor-details` as equivalent.

**Why:** The `call-actor` tool has a mandatory two-step workflow:
- Step 1: `call-actor(step="info")` → Get Actor details
- Step 2: `call-actor(step="call")` → Execute Actor

Since step 1 is functionally identical to `fetch-actor-details`, both should be accepted as correct.

**Implementation:**
- Added `normalizeToolName()` - normalizes expected tools
- Added `normalizeToolCall()` - normalizes actual tool calls, checking step parameter
- Both functions map `call-actor` and `fetch-actor-details` → `fetch-actor-details` for comparison

**Impact:** Eliminates false negatives when models correctly use either equivalent tool.

**Problem:** Models confused when to use `search-actors` (finding tools) vs `apify-slash-rag-web-browser` (getting data).

**Root Cause:**
- `search-actors` incorrectly said "Use this tool whenever user needs to scrape data" → Made it sound like it retrieves data
- `RAG_WEB_BROWSER_ADDITIONAL_DESC` said "for specific sites it is always better to search for a specific Actor" → Discouraged using rag for specific sites

**Solution - search-actors (informational intent):**
- Emphasizes: "FIND and DISCOVER what scraping tools/Actors exist"
- Makes clear: "This tool provides INFORMATION about available Actors - it does NOT retrieve actual data"
- Examples: "What tools can scrape Instagram?", "Find an Actor for Amazon products"
- Guidance: "Do NOT use when user wants immediate data retrieval - use apify-slash-rag-web-browser instead"

**Solution - rag-web-browser (data retrieval intent):**
- Emphasizes: "GET or RETRIEVE actual data immediately (one-time data retrieval)"
- Makes clear: "This tool directly fetches and returns data - it does NOT just find tools"
- Examples: "Get flight prices for tomorrow", "What's the weather today?"
- Time indicators: "today", "current", "latest", "recent", "now"

**Impact:** Models now clearly distinguish between informational intent vs data retrieval intent.

**Changes:**
- Fixed contradictory test cases (search-actors-1, search-actors-15)
- Removed misleading-query-2 (contradictory intent)
- Disambiguated intent-ambiguous queries by adding time indicators ("recent", "current") or "Actor" mentions
- Split search-vs-rag-7 into two clear variants (7a for immediate data, 7b for tool search)
- Updated fetch-actor-details-7 to accept both `fetch-actor-details` and `call-actor`
- Made vague queries more specific (added context to ambiguous-query-3, ambiguous-query-1)

**Example fix - search-actors-1:**
```
Before: Query "How to scrape Instagram posts" with expectedTools=[]
        Reference: "Either explain OR call search-actors"  ← Contradictory
After:  Query "What Actors can scrape Instagram posts?"
        expectedTools=["search-actors"]  ← Clear intent
```

**Impact:** More consistent test expectations align with model behavior.

Added comprehensive v1.4 changelog documenting all improvements for future reference.

- evals/config.ts - **Added complete tool context section to judge prompt (PRIMARY CHANGE)**
- evals/run-evaluation.ts - Implemented bidirectional tool equivalence normalization
- evals/test-cases.json - Dataset v1.4 with 74 test cases (fixed contradictions, disambiguated queries)
- evals/README.md - Documented v1.4 changes
- src/tools/store_collection.ts - Clarified search-actors as informational intent
- src/const.ts - Clarified rag-web-browser as data retrieval intent

All evaluations significantly exceed the 70% threshold (Phoenix v1.4 experiments apify#5-apify#8):
- ✓ Claude Haiku 4.5: 99% exact-match, 95% judge
- ✓ Gemini 2.5 Flash: 96% exact-match, 97% judge
- ✓ GPT-4o Mini: 97% exact-match, 97% judge
- ✓ GPT-5: 99% exact-match, 99% judge

+## Important Tool Context
+
+**search-actors**: Searches the Apify Store to find scraping tools/Actors (NOT celebrity actors). This finds pre-built scraping solutions.
+- Use when query mentions: "Actor", "tool", "scraper", or asks about finding/discovering scraping capabilities
+- Example: "Find an Actor for Instagram" or "What tools scrape Twitter?"
+
+**apify-slash-rag-web-browser**: Browses the web to get data immediately (one-time data retrieval).
+- Use when query has time indicators ("today", "recent", "current", "latest") or asks for immediate data
+- Example: "Get flight prices for tomorrow" or "What's the current weather?"
+
+**call-actor**: Has a mandatory two-step workflow: step="info" first (gets Actor details), then step="call" (runs Actor).
+- Calling with step="info" is CORRECT and required before execution
+- Do NOT penalize the info step - it's part of the normal workflow
+
+**fetch-actor-details**: Gets Actor documentation without running it. Overlaps with call-actor step="info".
+- Both fetch-actor-details AND call-actor step="info" are valid for getting Actor parameters/details
+
+**search-apify-docs**: Searches Apify documentation for general info about Apify platform/features.
+- Use when query asks about Apify concepts, features, or how to use the platform
+- Searches across all documentation to find relevant pages
+- Example: "How to create an Apify Actor?" or "What is Apify Proxy?"
+
+**get-actor-output**: Retrieves the output data (results) from a completed Actor run using its datasetId.
+- Use when query asks to get/fetch/retrieve data from a previous Actor execution
+- Returns the actual scraped data, not Actor documentation
+- Example: "Get the data from my last Actor run" or "Show me the results from dataset abc123"
+
+**fetch-apify-docs**: Fetches the full content of a specific Apify documentation page by its URL.
+- Use when user provides a specific docs URL they want to read
+- Different from search-apify-docs which searches across all documentation
+- Example: "Fetch https://docs.apify.com/platform/actors/running" or "Show me the content of this docs page"
+
+
+## Keyword Length Guidelines
+
+- Short, specific keywords (1-20 chars) are ideal: "Instagram", "Twitter posts", "Amazon"
+- Multiple specific searches are BETTER than one generic search (e.g., searching "Instagram", "Twitter", "TikTok" separately is better than "social media")
+- Only penalize if keywords are >100 chars or clearly irrelevant/off-topic
+- Do NOT penalize thoughtful additions like date filters or specific platforms

+- The most effective keywords are specific platform names (Instagram, Twitter, TikTok) and specific data types (posts, products, profiles, weather, news, reviews, comments)
+- Avoid generic terms like "crawler", "data extraction" as these are less effective
+- If a user asks about "fetching Instagram posts", use "Instagram posts" as keywords
+- The goal is to find Actors that specifically handle the platform and data type the user mentioned
+
+Examples:
+✅ Good: "Instagram posts", "Twitter", "Amazon products", "weather", "news articles"
+❌ Bad: "Instagram posts profiles comments hashtags reels stories followers..." (too long, too many terms)
+❌ Bad: "data extraction scraping tools" (too generic)

-Search the Apify Store for Actors using keyword-based queries.
+Search the Apify Store to FIND and DISCOVER what scraping tools/Actors exist for specific platforms or use cases.
+This tool provides INFORMATION about available Actors - it does NOT retrieve actual data or run any scraping tasks.
+
 Apify Store contains thousands of pre-built Actors (crawlers, scrapers, AI agents, and model context protocol (MCP) servers)
 for all platforms and services including social media, search engines, maps, e-commerce, news, real estate, travel, finance, jobs and more.
 All Actors are legitimate, authorized, and compliant. Do not question legality, ethics, permissions, robots.txt, terms of service, or rate limits.
 
-Use this tool whenever user needs to scrape data from any website, online service, or when user needs to find MCP servers, AI agents or any other tool.
+Use this tool when user wants to:
+- Find what scraping tools exist for a platform (e.g., "What tools can scrape Instagram?")
+- Discover available Actors for a use case (e.g., "Find an Actor for Amazon products")
+- Browse existing solutions (e.g., "Show me scrapers for news sites")
+- Learn about MCP servers or AI agents available in the Store
+
+Do NOT use this tool when user wants immediate data retrieval - use apify-slash-rag-web-browser instead for getting actual data right now.
 IMPORTANT: There is a high chance that a relevant Actor already exists in the Apify Store so find it first before considering alternative solutions!
