feat(github): enrich review items with Project Status

[patrick204nqh]

Summary

• add a post-fetch enrichment layer (registry + orchestrator hook) and an in-place store augmentation seam
• add GitHub GraphQL project-status enrichment that joins board Status onto review items via location+number
• surface Status in the UI via a new filter axis, review detail chip, project scope field, and bootstrap wiring

Checklist

• Tests added/updated and npm test passes
• npm run lint:anon is clean (no real repo names, org names, or tokens)
• npm run pack:smoke passes (if packaging/CLI/runtime changed)
• Keeps the single-file invariant — no external scripts, no CDN, no backend
• Follows the commit style in CONTRIBUTING.md (no AI co-author / attribution footer)

Notes

• Added tests: test/core/enrichment.test.ts, test/ingest/github/graphql.test.ts, test/ingest/github/project-source.test.ts, test/layout/review-status.test.ts, plus updates in test/core/store.test.ts and test/core/orchestrator.test.ts.
• Verified: npx tsc --noEmit, npm test (111 files / 462 tests), npm run lint:anon, npm run build:cli && node dist-cli/cli/index.js build --generic.
• Plan path note: the plan referenced src/runtime/shell/bootstrap.ts; this repo uses src/runtime/bootstrap.ts, and wiring was applied there.
