mcp discovery: enforce target-scoped run model and add protocol-aware static harvesting (mysql+pgsql)

Refactor the MCP query/discovery stack to remove prototype-era MySQL-only assumptions and make discovery/catalog semantics explicitly target-scoped. This commit is intentionally not backward compatible with legacy single-target catalog metadata.

Key implementation details:
- Discovery_Schema:
  - runs table now stores target_id, protocol, and server_version
  - resolve_run_id() now requires target_id and resolves schemas within target scope
  - create_run() now records target/protocol/server version
  - added legacy schema detection + destructive catalog table rebuild when old runs layout is found
  - fixed resultset lifetime/escaping issues in target-aware run resolution
- New PostgreSQL static harvester:
  - added PgSQL_Static_Harvester class and build wiring
  - harvests schemas/objects/columns/indexes/fks/view definitions into Discovery_Schema
  - maps pg metadata to object_id-based insert APIs used by Discovery_Schema
- Query_Tool_Handler:
  - constructor simplified to catalog_path only (no mcp-mysql_* runtime ctor deps)
  - discovery.run_static now requires target_id and dispatches protocol-aware harvester at runtime
  - catalog.*, agent.run_start, and llm.* tool contracts now require target_id when resolving run_id
  - all run_id resolution call sites switched to resolve_run_id(target_id, ...)
  - list_schemas catalog query now scoped by target_id via runs join
  - digest logging path now resolves run_id in target context
- ProxySQL_MCP_Server:
  - updated Query_Tool_Handler construction to new signature
- Docs updated:
  - added explicit target_id scoping guidance for discovery/catalog/agent/llm workflows
  - clarified protocol-aware routing and noted legacy examples still present in large script docs

Build validation:
- Recompiled changed objects with PROXYSQLGENAI=1:
  - Query_Tool_Handler.oo
  - Discovery_Schema.oo
  - PgSQL_Static_Harvester.oo
  - ProxySQL_MCP_Server.oo

Add multi-agent database discovery system

Implements a 4-agent collaborative system using Claude Code's
Task tool and MCP catalog for comprehensive database analysis:

- Structural Agent: Maps tables, relationships, indexes, constraints
- Statistical Agent: Profiles data distributions, patterns, anomalies
- Semantic Agent: Infers business domain and entity types
- Query Agent: Analyzes access patterns and optimization

Agents collaborate via MCP catalog across 4 rounds:
1. Blind exploration → 2. Pattern recognition →
3. Hypothesis testing → 4. Final synthesis

Includes simple_discovery.py demo and comprehensive documentation.
