persistent MCP client: warm handshake, keep-alive pool, error taxonomy, thread-safe

- IDAClient: single handshake, ~7ms warm calls (vs ~60ms cold CLI)
- keep-alive connection pool over http.client; concurrent-safe (40 threads OK)
- grounded error taxonomy: IDAToolError on isError, soft per-item errors as data
- session-expiry recovery (404 -> re-handshake -> retry), bounded transport retries
- auto db-injection + resolve_db (ignores stale empty-id sessions)
- live smoke test: 13/13 pass
