Address CodeRabbit review: timeout, session-id guard, CI hardening

[rakshith48]

Applies the actionable findings from the CodeRabbit review (PR #1).

• api() timeout — AbortController bounds every Firecrawl call (FIRECRAWL_HTTP_TIMEOUT_MS, default 60s), so a stalled request can't block the plugin's single response.
• session.id guard — browser.launch now validates session.id as well as cdpUrl; prevents reporting success when the session can't be closed later (leak).
• CI — persist-credentials: false on checkout.
• Tests — added a no-session-id case (10 total, still hermetic).

Deliberately skipped: SHA-pinning the GitHub Actions (@v4 → commit SHA). CI is hermetic (no secrets, no deploy, no publish), so the maintenance cost outweighs the supply-chain benefit here.

Verified: node --test (10/10) + live launch/close against the real Firecrawl API.

📝 Walkthrough

Walkthrough

The api() helper in bin/plugin.js gains an AbortController-based HTTP timeout configurable via FIRECRAWL_HTTP_TIMEOUT_MS (default 60 s), converting timeouts into a typed error. The browser.launch path adds a session.id presence check. Tests cover the missing-session-id failure path. The CI workflow disables credential persistence on checkout.

Changes

Plugin HTTP Timeout and Session ID Validation

Layer / File(s)	Summary
HTTP timeout, session.id validation, and tests bin/plugin.js, test/plugin.test.js	api() wraps fetch with an AbortController timeout (default 60 s via FIRECRAWL_HTTP_TIMEOUT_MS), clears the timer in finally, and converts AbortError into a timeout-specific error. browser.launch adds a session.id guard alongside the existing cdpUrl check. The mock server gains a ttl===999 branch that omits id, and a new test verifies the launch fails with an error matching /session id/.

CI Credential Persistence Hardening

Layer / File(s)	Summary
Disable persist-credentials in CI checkout .github/workflows/ci.yml	Adds persist-credentials: false to the actions/checkout@v4 step.

Poem

🐇 A rabbit hops in, checks the clock on each call,
No fetch shall hang stalled in an infinite stall.
The session needs id—without it, we fail,
And credentials vanish like snow in a gale.
Bounded and guarded, the burrow stays tight! 🕐
