fix(ci): install firefox in e2e-headless and fix e2e test isolation

- Updated `.github/workflows/ci.yml` to install both chromium and firefox in `e2e-headless` job, resolving missing executable errors.
- Updated `js/relayManager.js` to respect `__testRelays__` overrides (via URL/localStorage) during initialization, preventing race conditions where tests fell back to production relays.
- Updated `tests/e2e/repro_issue.spec.ts` to use dynamic relay ports based on worker index, preventing `EADDRINUSE` errors in parallel runs.
- Updated `scripts/check-hex.js` to ignore `docs/agents/task-logs/**` to prevent lint failures on hex strings in log files.
- Executed `prompt-curator-agent` daily task to fix broken paths in prompt library.
