feat(repo-health): add clickable health score breakdown panel

[mallya-m]

What does this PR do?

Makes the repo health score badge in TopRepos clickable. Clicking opens a panel showing a per-dimension breakdown of the score with actionable improvement tips.

Related issue

Closes #256

Changes made

• Created RepoHealthPanel.tsx component with 5 dimension breakdown
• Dimensions: Commit Activity, PR Merge Rate, PR Turnaround, Issue Load, Recent Activity
• Each dimension shows score out of 20, a progress bar, and a tip if score is low
• Made health badge in TopRepos.tsx a clickable button that opens the panel
• Panel closes on backdrop click or ✕ button
• Uses existing signals data from /api/metrics/repo-health — no new API calls

How to test

1. Sign in and go to the dashboard
2. Find the Top Repositories widget
3. Click any colored score badge (green/yellow/red number)
4. Panel opens showing breakdown for that repo
5. Click outside or ✕ to close

Could you please add the gssoc:approved and type:feature labels?
Thank you!

The health panel feature looks great — clean component, proper CSS vars, good a11y. However PR #303 (sortable columns) just merged and it touched the same area of TopRepos.tsx, so this PR now has a conflict.

Please rebase onto main:

git fetch upstream
git rebase upstream/main

When resolving conflicts in TopRepos.tsx: the sort state/logic is already in main from #303, so keep that and layer your activeHealthRepo state and the badge→button change on top. The RepoHealthPanel.tsx file has no conflict.

Once rebased and pushed, I'll merge.

@Priyanshu-byte-coder conflict resolved and rebased onto main — ready for merge!

Good feature. Two accessibility issues:

1. Dialog missing aria-labelledby
role="dialog" aria-modal="true" without aria-labelledby — screen readers won't know the dialog's title. Add an id to the <h2> and reference it:

<div role="dialog" aria-modal="true" aria-labelledby="health-panel-title">
  ...
  <h2 id="health-panel-title" ...>Health Breakdown</h2>

2. No Escape key to close
Modal panels should close on Escape. Add to RepoHealthPanel:

useEffect(() => {
  const handler = (e: KeyboardEvent) => { if (e.key === 'Escape') onClose(); };
  document.addEventListener('keydown', handler);
  return () => document.removeEventListener('keydown', handler);
}, [onClose]);

Everything else is solid — proper aria-hidden on overlay, aria-label on close button, CSS vars for layout colors, and the score-bar semantic colors (green/yellow/red) are appropriate for health indicators.

Hi @Priyanshu-byte-coder

Resolved the merge conflict and synced package-lock.json with the latest dependencies after rebasing onto main.

Also addressed the requested accessibility updates:

• Added aria-labelledby
• Added Escape key handling for modal close
• Fixed React hook ordering issue

All checks are passing locally now.
Ready to Merge !

1. Hardcoded colors — bg-green-500, bg-yellow-500, bg-red-500 in ScoreBar and text-green-400, text-yellow-400, text-red-400 in grade badge. Use CSS vars (var(--success), var(--destructive), or var(--accent)). 2. supabase/.temp/cli-latest committed — local Supabase temp file must not be in the repo. Add supabase/.temp/ to .gitignore and remove from branch. 3. .gitignore shows as binary diff — investigate encoding corruption. 4. Missing EOF newlines on RepoHealthPanel.tsx and TopRepos.tsx. 5. No-health-data fallback removed — repos with no health score now show nothing. Restore the -- fallback badge. 6. package-lock.json churn — unrelated npm version artifacts. Revert.

[mallya-m]

@Priyanshu-byte-coder all 6 issues addressed:

1. Replaced hardcoded bg-green/yellow/red with CSS vars
2. Restored -- fallback badge for repos with no health data
3. Added supabase/.temp/ to .gitignore and removed from tracking
4. Reverted package-lock.json churn
5. Added EOF newlines to RepoHealthPanel.tsx and TopRepos.tsx
6. Verified .gitignore encoding

Ready for merge!

Issues found in this PR:

• Missing EOF newline — add a trailing newline to all modified files.

• Raw Tailwind color classes — replace text-red-* / bg-red-* with text-[var(--destructive)] / appropriate CSS var equivalents. All colors must use CSS variables for theme support.

[mallya-m]

@Priyanshu-byte-coder addressed both issues:

1. Replaced all raw Tailwind color classes with CSS vars — var(--accent), var(--destructive), var(--warning,#ca8a04)
2. Fixed EOF newlines — single trailing newline on all modified files
3. Rebased onto latest main

Ready for merge!

[Priyanshu-byte-coder]

Two issues:

1. Missing EOF newline
2. Hardcoded fallback hex in CSS vars — var(--warning, #ca8a04) — remove the fallback. The var should be defined in globals.css. Since --warning is now defined in main (via merged PRs), just use var(--warning).
