Lighthouse for Flutter: scoring app performance 0–100 in one tap

So I built flutter_lighthouse. You wrap your app, tap a button, and it:

• auto-walks your routes (push → dwell → scroll → collect → pop)
• scores performance 0–100 using Chrome Lighthouse's log-normal curves
• lists findings with severity + a fix + a code example:
  • "FeedItem rebuilt 2562× on /feed" → wrap in const / Selector
  • "hero.jpg decoded 28× larger than displayed" → set cacheWidth
  • "30 frames >100ms on /heavy" → move work off the UI thread
• exports JSON (CI), Markdown (PR), HTML (shareable)

Detection is real, not guessed: rebuild counts via an opt-in LighthouseProbe,
oversized images via debugOnPaintImage (decoded vs displayed), frame timing via
addTimingsCallback. Scoring is deterministic and documented (SCORING_SPEC.md).

I validated it on an intentionally-bad example app — catches all the planted
regressions with 0 false positives. 54 tests, analyze clean.

It's v0.1.0 — feedback very welcome, especially on scoring weights and false
positives in real apps. What would you want audited next (network? bundle size?)
