🧹 refactor: Extract section validation logic to shared utility

[seonghobae]

🎯 What: Extracted duplicated section validation logic from roles/extractor.py, ranges/analyzer.py, and chords/analyzer.py into a new validate_section utility function in sections/utils.py.
💡 Why: This reduces code duplication and improves maintainability by centralizing the validation logic and logger warning.
✅ Verification: Verified by ensuring the refactored code passes all 272 existing tests in the analysis-engine package with no regressions.
✨ Result: Improved codebase readability and maintainability without altering functionality.

I have pushed an update to fix the CI failure. It appears that the trivy-fs-scan was failing because the root package-lock.json contained an outdated version of brace-expansion. I have updated minimatch in package.json to require a newer version, forcing brace-expansion to upgrade to a secure version in package-lock.json.

I have successfully run npm audit fix which updated the package-lock.json and resolved the moderate vulnerability in the brace-expansion transitive dependency (which was preventing the CI trivy-fs-scan job from passing). I also ran local CI checks and they are green. Pushed as requested!

Merged current develop and rebuilt this as the narrow shared section-validation refactor.

Validation:

• uv run --project services/analysis-engine pytest services/analysis-engine/tests/test_chords.py services/analysis-engine/tests/test_ranges.py services/analysis-engine/tests/test_roles.py services/analysis-engine/tests/test_roles_ml.py -q -> 43 passed.
• (cd services/analysis-engine && uv run ruff check src tests) -> passed.
• (cd services/analysis-engine && uv run ruff format --check src tests) -> passed.
• python3 scripts/checks/verify_supply_chain.py -> passed.
• Guard check for stale script/workflow/lockfile changes -> passed.

Notes:

• Final diff is only chords/analyzer.py, ranges/analyzer.py, roles/extractor.py, sections/__init__.py, and new sections/utils.py.
• Kept the current range overlap optimization from develop.
• Kept the current RoleExtractor _build_roles structure from develop, avoiding the old N+1 role-building regression.
• Dropped stale script formatting, workflow, supply-chain parser, YouTube, lockfile, and unrelated develop drift from this PR.

@seonghobae Thank you for the thorough validation summary — all checks passing, clean scope, and the N+1 regression avoided. Approving now.

I have verified that the updated branch includes the exact requested files (chords/analyzer.py, ranges/analyzer.py, roles/extractor.py, sections/__init__.py, and sections/utils.py) without unrelated drift from develop. Also verified the tests pass and no linting issues exist. Pushed.
