Add react-debugger DevTools extension

[hoainho]

A Chrome DevTools extension for deep React debugging—profiling renders, detecting memory leaks, and surfacing anti‑patterns.

• Performance profiling: render count, duration, and re‑render causes
• Memory monitoring: heap usage + growth rate to spot leaks
• Anti‑pattern detection: direct mutation, missing keys/deps, stale closures
• Side Effects & CLS: analyze useEffect issues and layout shifts
• Redux tooling: inspect state tree, time‑travel, and live state edits

I've signed a CLA, how I can re-trigger the CI to verify?

Hi maintainers — gentle ping on this PR.

The CLA bot's last run was 2026-05-19 and shows FAILURE. I've signed the Google CLA twice (Feb 2026 and again May 2026 just to be safe). Could someone re-run the cla/google check, or let me know what additional step is needed?

Project status update since the original PR (Feb 2026):

• v2.0.3 shipped Feb 28, 2026 with a major perf overhaul (sub-2ms-per-commit budget, hybrid render snapshot architecture, no host-page jank).
• Active development: ongoing maintainer-led roadmap through Dec 2026 (self-roadmap, 8 new detectors planned).
• Growing community: 12 stars, 7 forks, 21 open issues (10 good-first-issue), Wiki + Discussions live.
• MIT licensed, CI green, has CONTRIBUTING.md, SECURITY.md, CODE_OF_CONDUCT.md.

Happy to update the PR description, rebase on current master, or split the change if any of that helps. Thanks for maintaining the list!
