fix(docker): update GeoLite2-Country.mmdb checksum + automation

Fixes critical Docker build failure caused by upstream GeoLite2 database
update without corresponding Dockerfile checksum update.

**Root Cause:**
- GeoLite2-Country.mmdb file updated upstream
- Dockerfile still referenced old SHA256 checksum
- Build aborted at checksum verification (line 352)
- Cascade "blob not found" errors for all COPY commands

**Changes:**
- Update Dockerfile ARG GEOLITE2_COUNTRY_SHA256 to current value
- Add automated weekly checksum update workflow (.github/workflows/update-geolite2.yml)
- Implement error handling: retry logic, format validation, failure notifications
- Document rollback decision matrix with 10 failure scenarios
- Create comprehensive maintenance guide (docs/maintenance/geolite2-checksum-update.md)
- Update CHANGELOG.md and README.md with maintenance references

**Verification:**
- Checksum verified against current upstream file: 436135ee...
- Pre-commit hooks: PASSED (EOF/whitespace auto-fixed)
- Trivy security scan: PASSED (no critical/high issues)
- Dockerfile syntax: VALID
- GitHub Actions YAML: VALID
- No hardcoded secrets or injection vulnerabilities

**Automation Features:**
- Weekly scheduled checks (Monday 2 AM UTC)
- Auto-PR creation when checksum changes
- GitHub issue creation on workflow failure
- Comprehensive error handling and retry logic

**Impact:**
- Unblocks all CI/CD Docker image builds
- Enables publishing to GHCR/Docker Hub
- Prevents future checksum failures via automation
- Zero application code changes (no regression risk)

**Documentation:**
- Implementation plan: docs/plans/geolite2_checksum_fix_spec.md
- QA report: docs/reports/qa_geolite2_checksum_fix.md
- Maintenance guide: docs/maintenance/geolite2-checksum-update.md

**Supervisor Recommendations Implemented:**
- #1: Checksum freshness verification before update
- #3: Rollback decision criteria (10 scenarios)
- #4: Automated workflow error handling

+            🤖 **Automated GeoLite2 Database Checksum Update**
+
+            The GeoLite2-Country.mmdb database has been updated upstream.
+
+            ### Changes
+            - **Old checksum:** `${{ steps.checksum.outputs.old }}`
+            - **New checksum:** `${{ steps.checksum.outputs.current }}`
+            - **File modified:** `Dockerfile` (line 352)
+
+            ### Verification Required
+            - [ ] Local build passes: `docker build --no-cache -t test .`
+            - [ ] Container starts successfully
+            - [ ] API health check responds: `curl http://localhost:8080/api/v1/health`
+            - [ ] CI build passes
+
+            ### Testing Commands
+            ```bash
+            # Verify checksum locally
+            curl -fsSL "https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-Country.mmdb" | sha256sum
+
+            # Build and test
+            docker build --no-cache --pull -t charon:test-geolite2 .
+            docker run --rm charon:test-geolite2 /app/charon --version
