feat(ingestion): Phase 1 data spine — Grants.gov, PND RSS, NHDOJ registry, ProPublica enrichment

Core: icpBandForRevenue (100K-5M primary), serverUpsertOrgFromRegistry
(case-insensitive name/city/state key, new-registrant signal),
serverEnrichOrg (IRS fields + re-band, all-null marks attempted),
serverListOrgsNeedingEnrichment.

Worker: four source verticals, each a thin fail-loud client + pure
tested normalize layer + DBOS scheduled workflow:
- ingestGrants (nightly): Search2 paginated (cap 1000) -> fetchOpportunity
  details (cap 200, logged drops, 250ms politeness) -> batched upsert
- ingestPndRss (nightly): RSS via fast-xml-parser, heuristic funder/
  deadline extraction, link-keyed upsert
- ingestNhdojOrgs (monthly): pdfjs-dist positioned-text extraction, pure
  row reconstruction (multi-line names, inferred columns, fail-loud on
  layout change), registry upsert; no-op warn when PDF URL unset
- enrichOrgs (daily): ProPublica search -> conservative name/city match
  (null beats guess) -> latest-filing revenue/NTEE/FYE, per-org steps for
  checkpointed resume, >20% batch failure rethrows

94 worker + 16 core + 5 ai tests green; docs/features/ingestion.md added.
