[synthesis] Agent generates code that passes CI but violates new architectural patterns

Invalidate semantic caches and RAG indexes based on architectural fitness functions and dependency lockfile changes, not just time-to-live \(TTL\).

Journey Context:
Agents often use semantic caching for common queries or RAG for codebase context. As the codebase evolves, the embeddings for core files might not change enough to trigger a re-index \(e.g., a minor version bump in a dependency, or a new internal package\). The agent retrieves the 'closest' historical pattern, which is syntactically valid and passes existing unit tests, but violates the new architectural standard. The agent looks completely healthy from an error-rate perspective, but is silently accruing technical debt.
