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.

-# Action Plan - Final Execution Status
-
-**Date**: 2025-01-12  
-**Status**: ✅ **MAJOR PROGRESS** - 2 of 3 Priorities Complete
-
----
-
-## ✅ Priority 2: COMPLETE
-
-### Ethereum Mainnet Configuration ✅✅✅
-
-**Status**: **FULLY COMPLETE**
-
-- ✅ **WETH9 Bridge**: Ethereum Mainnet configured
-  - Destination: `0x2a0840e5117683b11682ac46f5cf5621e67269e3`
-  - Chain Selector: `5009297550715157269`
-  - Transaction: Sent and confirmed
-
-- ✅ **WETH10 Bridge**: Ethereum Mainnet configured
-  - Destination: `0x2a0840e5117683b11682ac46f5cf5621e67269e3`
-  - Chain Selector: `5009297550715157269`
-  - Transaction: Sent and confirmed
-
-**Impact**: This was a **critical blocker** that is now **RESOLVED**.
-
----
-
-## ⏳ Priority 1: IN PROGRESS
-
-### LINK Token Deployment
-
-**Status**: ⏳ **DEPLOYED, PENDING CONFIRMATION**
-
-- ✅ Deployment transaction sent
-- ✅ Address: `0x0cb0192C056aa425C557BdeAD8E56C7eEabf7acF`
-- ✅ Mint transaction sent (1M LINK)
-- ⏳ Waiting for network confirmation
-
-**Note**: Transactions are in the mempool. Network confirmation typically takes 1-5 minutes.
-
----
-
-## ⏳ Priority 3: PENDING
-
-### Bridge Funding
-
-**Status**: ⏳ **WAITING FOR LINK TOKEN**
-
-- ⏳ Cannot proceed until LINK token confirms
-- ✅ Script ready: `fund-bridge-contracts.sh`
-- ✅ Will execute automatically once LINK confirms
-
-**Required**: 20 LINK total (10 per bridge)
-
----
-
-## Readiness Check Results
-
-### Before Action Plan
-- **Passed**: 17
-- **Failed**: 3
-- **Warnings**: 2
-
-### After Action Plan
-- **Passed**: 19 ✅ (+2)
-- **Failed**: 1 ⚠️ (-2)
-- **Warnings**: 2
-
-### Improvements
-1. ✅ **Ethereum Mainnet Configuration**: Fixed (was failing, now passing)
-2. ✅ **Bridge Destination Status**: Both bridges now configured
-3. ⏳ **LINK Token**: Deployed but pending confirmation
-
----
-
-## Current System State
-
-### ✅ Fully Operational
-- Network connectivity
-- Account status (999M+ ETH)
-- Bridge contracts deployed
-- **Ethereum Mainnet destinations configured** ✅
-- Configuration files
-- All scripts available
-
-### ⏳ Pending Network Confirmation
-- LINK token deployment
-- LINK token minting
-- Bridge funding (automatic after LINK confirms)
-
----
-
-## Next Steps
-
-### Automatic (Once LINK Confirms)
-1. LINK token will be verified
-2. Mint will be confirmed
-3. Bridges will be funded automatically
-
-### Manual Verification
-```bash
-# Check LINK token
-cast code 0x0cb0192C056aa425C557BdeAD8E56C7eEabf7acF --rpc-url http://192.168.11.250:8545
-
-# Re-run readiness check
-./scripts/full-readiness-check.sh
-```
-
----
-
-## Summary
-
-**Major Achievement**: ✅ **Ethereum Mainnet configuration complete**
-
-This was one of the 3 critical blockers. The system can now route to Ethereum Mainnet once LINK token confirms and bridges are funded.
-
-**Remaining**: LINK token confirmation (network-dependent, typically 1-5 minutes)
