🛡️ Sentinel: Conclude security review without codebase modifications

[ManupaKDU]

Explored the codebase and identified that the repository has already been extensively fortified by previous Sentinel and Bolt iterations. The automated security scans (Bandit) yielded no new, actionable vulnerabilities beyond acknowledged false positives in unit tests (B603/B104) and generic warnings (B404).

No modifications to the source code were strictly necessary. Pre-commit procedures were executed successfully to conclude the assessment.
