feat(programs): add per-program scope summary endpoint and inline UI counts

- New POST /api/scope/program-summaries endpoint fetches scope details on
  demand for a list of (platform, handle) pairs. Results are cached so
  repeat lookups are cheap.
- fetchH1Programs / fetchH1WithREST / fetchBCPrograms grow an includeScope
  flag; when true they call fetchH1ScopeSummary / fetchBCScopeSummary per
  program to populate in-scope and out-of-scope target counts.
- programScopeCacheKey + cache plumbing keys results by (platform, handle).
- programs.js renders scope counts inline in the monitoring table and
  triggers the summary endpoint as rows become visible.
- .gitignore: exclude local .cache/ directory used by the new cache layer.
