feat(infra): migrate Bedrock KB vector store to Aurora pgvector (#125) Replaces OpenSearch Serverless with Aurora PostgreSQL Serverless v2 + pgvector as the Bedrock Knowledge Base vector store (v1 PR3). Bedrock KB requires Aurora SSv2 (RDS Data API), not a plain RDS instance — so the DB engine moves to Aurora. - foundation: rds.DatabaseInstance (PG15) -> rds.DatabaseCluster Aurora SSv2 (0.5-4 ACU, enableDataApi). RDS alarms: free-storage -> freeable-memory. - compute: delete all AOSS (collection, policies, VPC endpoint, index-creator); add bedrock_user secret + KB role (scoped rds-data + secret read); repoint CfnKnowledgeBase to RDS storage (bedrock_integration.bedrock_kb, vector(1024)). - lambdas: oss-index-creator -> aurora-pgvector-init (bootstrap schema/table/ indexes/role via RDS Data API; transient-error retry; password guard). - ADR 0001 documents the decision. Eliminates the ~$175-350/mo AOSS OCU floor. NAT kept (egress still needed). GPT-4.1 cross-review: no BLOCK (FIX applied). tsc clean; foundation synth shows Aurora cluster with Data API enabled; 23 pytest pass.
