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.

-# Corrected Blockscout Fix Commands
-
-## Issues Found
-1. Container is not running, so can't use `--network container:$BLOCKSCOUT_CONTAINER`
-2. System uses `docker-compose` (with hyphen) not `docker compose`
-3. Need to use postgres container's network instead
-
-## Corrected Commands (Run in VMID 5000)
-
-### Step 1: Run Migrations Using Postgres Network
-
-```bash
-# Get postgres container network
-POSTGRES_NETWORK=$(docker inspect blockscout-postgres | grep -A 20 "Networks" | grep -oP '"NetworkID": "\K[^"]+' | head -1)
-
-# Or use the network name directly
-NETWORK_NAME=$(docker inspect blockscout-postgres -f '{{range $key, $value := .NetworkSettings.Networks}}{{$key}}{{end}}')
-
-# Run migrations using postgres network
-docker run --rm \
-  --network $NETWORK_NAME \
-  -e DATABASE_URL=postgresql://blockscout:blockscout@blockscout-postgres:5432/blockscout \
-  blockscout/blockscout:latest \
-  bin/blockscout eval "Explorer.Release.migrate()"
-```
-
-### Step 2: Alternative - Use Docker Network Bridge
-
-```bash
-# Find the bridge network
-BRIDGE_NETWORK=$(docker network ls | grep bridge | awk '{print $1}' | head -1)
-
-# Run migrations
-docker run --rm \
-  --network $BRIDGE_NETWORK \
-  --add-host=postgres:$(docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' blockscout-postgres) \
-  -e DATABASE_URL=postgresql://blockscout:blockscout@postgres:5432/blockscout \
-  blockscout/blockscout:latest \
-  bin/blockscout eval "Explorer.Release.migrate()"
-```
-
-### Step 3: Simplest - Use Host Network
-
-```bash
-# Use host network and connect to localhost
-docker run --rm \
-  --network host \
-  -e DATABASE_URL=postgresql://blockscout:blockscout@localhost:5432/blockscout \
-  blockscout/blockscout:latest \
-  bin/blockscout eval "Explorer.Release.migrate()"
-```
-
-### Step 4: Update docker-compose.yml (Use docker-compose with hyphen)
-
-```bash
-cd /opt/blockscout  # or wherever docker-compose.yml is
-
-# Backup
-cp docker-compose.yml docker-compose.yml.backup
-
-# Update command - check current command first
-grep -A 2 "command:" docker-compose.yml
-
-# Update to run migrations before start
-sed -i 's|command:.*blockscout start|command: sh -c "bin/blockscout eval '\''Explorer.Release.migrate()'\'' \&\& bin/blockscout start"|' docker-compose.yml
-sed -i 's|command:.*/app/bin/blockscout start|command: sh -c "bin/blockscout eval '\''Explorer.Release.migrate()'\'' \&\& bin/blockscout start"|' docker-compose.yml
-```
-
-### Step 5: Restart Using docker-compose (with hyphen)
-
-```bash
-cd /opt/blockscout
-docker-compose down blockscout
-docker-compose up -d blockscout
-
-# Wait and check
-sleep 30
-docker ps | grep blockscout
-docker logs blockscout 2>&1 | tail -20
-```
-
-## Complete One-Line Fix
-
-```bash
-# Run migrations using host network
-docker run --rm --network host -e DATABASE_URL=postgresql://blockscout:blockscout@localhost:5432/blockscout blockscout/blockscout:latest bin/blockscout eval "Explorer.Release.migrate()" && \
-cd /opt/blockscout && \
-sed -i 's|command:.*blockscout start|command: sh -c "bin/blockscout eval '\''Explorer.Release.migrate()'\'' \&\& bin/blockscout start"|' docker-compose.yml && \
-docker-compose restart blockscout
-```
