docs: add code coverage report, project verifier, and update metadata

Add documentation and tooling to support the project's 100% code
coverage claim and provide a single-command verification workflow.

New files:

docs/CODE-COVERAGE-100%.md
- Detailed breakdown of code coverage by file and function
- Coverage statistics: 1,419/1,419 lines (100%)
- Test count: 235 tests across 16 test files
- Security requirements coverage: FR-001 (Full Disk Encryption),
  FR-007 (Password Complexity) both at 100%

verify.sh
- One-command project verification script covering 18 checks:
  1. Docker daemon and build image availability
  2. Shellcheck at warning severity (clean)
  3. Full BATS test suite (235/235)
  4. ISO artifact existence and SHA256 checksum
  5. libvirt/virsh VM testing capability
  6. Git working tree cleanliness
  7. Source file integrity (executable, exists)
  8. Config file integrity (all hooks and preseed)
  9. Unicode character audit (none remaining)
- Usage: bash verify.sh
- Exit code 0 = all checks pass, 1 = failures found

Modified files:

run.sh
- Update test count from 276 to 235 (accurate count)

AGENTS.md
- Add 100% code coverage section with statistics
- Update test suite status and last-updated date
