fix(windows-ci): catch destructured join() bin-spawns + browse server tests

Browse Source 
Round 5 of windows-free-tests fixes. Round 4 caught Playwright launchers
but two more failure shapes appeared in shard 5:

1. test/diff-scope.test.ts uses `import { join }` (destructured) and
   `join(import.meta.dir, '..', 'bin', 'gstack-diff-scope')`. My round-3
   pattern only matched `path.join(...)` — the destructured form slipped
   through. Tightened the pattern to match the literal `, 'bin', '<name>'`
   path-segment shape regardless of whether it's `path.join` or `join`
   directly.

2. browse/test/sidebar-integration.test.ts spawns the browse server via
   `spawn(['bun', 'run', server.ts])` with BROWSE_HEADLESS_SKIP=1. The
   Bun-run-server.ts path is the same Playwright-on-Windows broken path
   that the windows-free-tests job intentionally avoids — the server-node.mjs
   route only kicks in for the compiled binary, not direct Bun runs of the
   TypeScript source. Added a BROWSE_HEADLESS_SKIP / spawn-bun-run pattern.

Curated Windows subset: 72 → 73 tests (~57% of free suite). Net up by 1
because the tightened bin pattern released one test that was a false
positive in the loose `path\\.join` form.
