feat(coams): Implement AI-First Markdown CMS Engine
- Implement pure Go ignorant engine for AST Markdown parsing (goldmark), chunking, and Edge validation. - Orchestrate Temporal Saga Lifecycle verifying Agent-Index graph integrity before Upsert. - Provision AlloyDB Zero-Leak partitioning architecture using pgvector. - Bind Google Workspace IAM tokens to physical channel_id shard limits. - Inject self-bootstrapping SKILL.md into QuanuX Knowledge Vector. - Establish GitHub Actions CI matrix with parsing Fuzzer, Temporal mocks, and Docker AlloyDB Omni Simulation.

Instead, GERP employs the **Golden Thread**: strict UUID pointers managed entirely in application space. A `SalesOrder` in `internal/revenue` physically stores a `CustomerID` (UUID), but it never explicitly joins that to the `mdm.GlobalEntities` table at the Spanner level. The graph stitching occurs strictly in memory at the BFF level.
