Add store to manifest regen, soften repo-health matchers

Store package ships /oclif.manifest.json but the prepack didn't regenerate
it — same bug the test is meant to catch. Add `pnpm oclif manifest` to
store's prepack alongside the other six packages.

Per Copilot review feedback, soften the repo-health matchers so the test
doesn't miss legitimate variants:
- files entries: match any path ending in `oclif.manifest.json` (covers
  `'oclif.manifest.json'` and globs in addition to `'/oclif.manifest.json'`)
- prepack script: match `oclif manifest` via word-boundary regex (covers
  `pnpm exec oclif manifest`, `pnpm --silent oclif manifest`, etc.)
