fix: add 5-min job timeout and wrap Windows binary verification with 30s timeout

The Windows CI job was hanging in the install script at the binary
verification step (lines 376/399): `"$BINARY_PATH" --help` and
`"$BINARY_PATH" version` can stall indefinitely while Windows Defender
scans the newly downloaded executable.

- .github/workflows/install.yml: add `timeout-minutes: 5` to the
  test-install job so a hung Windows runner is killed in under 5 minutes
  instead of consuming the full runner quota (previously 3+ hours)
- install-gh-aw.sh / actions/setup-cli/install.sh: set BINARY_EXEC_TIMEOUT
  to `timeout 30` on Windows, wrap both binary verification calls with it;
  on timeout emit a warning and continue rather than failing the install
  (the binary has already passed checksum verification so it is safe to use)
