ci: integrate hardcoded path linter into CI workflow (#865)

PR #864 adds lint_hardcoded_paths.py but it's not in CI.

New scripts/lint_hardcoded_paths.py:
- Scans for 6 hardcoded ~/.hermes path patterns
- Skips hermes_constants.py (source of truth), comments, docs
- --json output, --fix suggestions
- Exit code 1 on findings (fails CI)

Updated .github/workflows/tests.yml:
- New lint-paths job runs on every push/PR to main
- Runs: python3 scripts/lint_hardcoded_paths.py
- Separate from test job for fast failure

Closes #865
