chore: consolidate documentation — delete status/fix/progress cruft

Before: 335 tracked .md files; top level had 14 README-like docs;
docs/ contained ~234 files, most of them auto/LLM-generated status
reports (ALL_*_COMPLETE*, *_FIX*, DEPLOYMENT_*_FINAL*, etc.).

After: 132 tracked .md files. Repo now has exactly five top-level
docs: README.md, QUICKSTART.md, RUNBOOK.md, CONTRIBUTING.md,
CHANGELOG.md (moved up from docs/).

Keeper philosophy in docs/:
- API, CCIP (ops + security + receiver/router refs), Chainlist refs,
  compliance, deployment (guides not status), database connection,
  legal compliance, metamask integration, production checklist,
  tiered-architecture implementation/setup, reusable-components plan,
  token-mechanism doc, wrap-and-bridge operational reference, plus
  docs/specs/** and docs/api/ / docs/openapi/ trees.

Deleted (git history preserves provenance):
- All 'ALL_*_COMPLETE*' / '*_FIX*' / '*_FIXED*' / '*_FINAL*' /
  '*_STATUS*' / '*_PROGRESS*' / '*_SUMMARY*' files.
- BLOCKSCOUT_*_FIX / _CRASH / _INITIALIZATION / _SCHEMA / _YAML /
  _SKIP / _NEXT_STEPS / _START_AND_BUILD / _DATABASE_CREDENTIALS
  (the last contained passwords).
- CCIP_IMPLEMENTATION_* / CCIP_CURRENT_STATUS / CCIP_GAP_*
  (gap analyses are not a sustained reference).
- NPMPLUS_CREDENTIALS_GUIDE.md (contained creds).
- LETSENCRYPT_CONFIGURATION_GUIDE.md (contained creds; will be
  re-introduced as runbook content post-secrets-scrub).
- docs/diagnostic-reports/, docs/feature-flags/ (run-time artifacts).

README.md: dead links (START_HERE, README_DEPLOYMENT, COMPLETE_DEPLOYMENT,
DEPLOYMENT_COMPLETE_FINAL) replaced with links to the five canonical
top-level docs + docs/ index.
