feat: introduce RowLink primitive and migrate leaderboard (#266)

[edwin-rivera-dev]

Summary

Introduces a shared RowLink primitive that renders clickable list rows as real <a href> elements, and migrates the Leaderboard surface (TopMinersTable rows + MinerCard) to use it. Middle-click, Cmd/Ctrl-click, and right-click "Open link in new tab" now all work on the Top Miners and Discoveries pages.

What changed

New primitive — src/components/common/RowLink.tsx

A thin <a href> wrapper that:

• On plain left-click: calls preventDefault() and navigate(href, { state }) so React Router handles the transition (no full page reload, back-stack preserved, same UX as today)
• On modifier-click / middle-click / right-click: lets the browser handle it — native "new tab", native context menu, native drag-to-bookmark, etc.
• Respects defaultPrevented so nested clickable elements (copy buttons, inline links) keep working when they e.stopPropagation()

Migrations

• MinerCard: replaced onClick: () => void prop with href + linkState. Wraps the card body in <RowLink>.
• TopMinersTable: replaced onSelectMiner with a getHref(miner) prop and optional linkState. Every row (desktop + mobile card) is now a RowLink.
• TopMinersPage and DiscoveriesPage: drop their handleSelectMiner callbacks; pass a URL builder and backLabel in linkState instead.

Unchanged

• Plain left-click behavior on every migrated row — same target URL, same React Router transition, same back-button state. No visual changes, no animation changes.

Motivation (from #266)

Rows built with onClick + useNavigate() silently break every browser-native navigation idiom users expect from a list of links: middle-click, Cmd-click, right-click "Open in new tab", drag-to-bookmark. Fixing this with custom onAuxClick + modifier handlers only covers middle- and Cmd-click — the right-click context menu only surfaces "Open link in new tab" when the element is a real <a>. So the primitive is the right abstraction.

Scope

Intentionally limited to the Leaderboard surface for this PR. The other ~14 surfaces called out in #266 (Dashboard, Repositories page, Repository detail tabs, Miner detail tabs, PR detail header, Bounties, Search) will follow as individual PRs using the same primitive — each small and independently reviewable.

Type of Change

• Feature / enhancement

Testing

• npm run build
• npm run lint:fix
• Manual on /top-miners:
  • Plain click on a miner row → navigates to detail page, back label is Back to Leaderboard ✓
  • Middle-click on a row → opens detail page in new tab ✓
  • Cmd-click / Ctrl-click on a row → opens in new tab ✓
  • Right-click → context menu shows "Open link in new tab" ✓
  • Hover shows the destination URL in the browser's status bar ✓
• Manual on /top-miners?mode=discovery and /discoveries — same four behaviors; detail page opens with mode=issues, back label is Back to Discoveries.
• Any internal clickable element inside a row (e.g. hotkey copy, sort chip) still works and does not navigate to the row's detail URL (guarded by e.stopPropagation()).
• Keyboard: Tab focuses the row; Enter activates the link.

Checklist

• No behavior change for plain left-click
• No new dependencies
• New primitive is framework-generic — reusable in follow-up PRs
• URL construction moved into leaf components (closes the getMinerHref / linkState part of the issue)

Follow-ups (out of scope)

One PR per surface:

• Dashboard — Live Activity + Repositories table
• Repositories page — trending, most collateral, recent PRs, main table
• Repository detail — PRs, bounties, GitHub issues, contributors
• Miner detail — PRs, repositories, score breakdown
• PR detail header — repo avatar / name / author
• Bounties — available, pending, history, issue submissions
• Search — miners, repositories, PRs, issues
• LeaderboardSidebar (discoveries sidebar on XL viewports)

@anderdc Please review my PR asap. I appreciate.
Thanks.

Good fix — proper link semantics for miner cards. Needs CI to pass (no checks have run yet). Push or retrigger to get build/format results.

Hi @anderdc I have just fixed CI error.
Could you review again please?
