Polygres Agent Skills 0.5.0

Added

• Added synchronized-project guidance across all five skills for Supabase, Neon, and PostgreSQL sources.
• Added deterministic pipeline-plan guards for synchronized projects, including target schema, imports, writes, credentials, capture workers, and sync-control boundaries.
• Added sync-aware scaffolding and review output for source authority, table selection, managed replication, reconfiguration, and source-only writes.
• Added preflight, lifecycle, generation-conflict, schema-drift, resync, and permission troubleshooting guidance.

Changed

• Required project-mode resolution before choosing CLI, SDK, database, ingestion, or retrieval surfaces.
• Directed synchronized-project creation and initial table selection to the CLI or dashboard while keeping source credentials out of agent-visible paths.
• Documented the standard and synchronized project creation command surfaces.
• Restricted synchronized-project SDK and API-key guidance to supported retrieval, catalog, and readiness surfaces.
• Updated Context and retrieval design for embeddings generated in synchronized source databases.
• Coordinated guidance with polygres-sdk 0.4.0 and polygres-cli 0.4.0.
