[NOTICKET][AI] perf(chat): PR-DB1 - memoizing catalog reader + shared ChatHandler
Rifqi Hafizuddin +1: Claude Opus 4.8Cut redundant catalog-DB round-trips in the slow path and stop rebuilding the Azure LLM clients per request. - MemoizingCatalogReader (catalog/reader.py): request-scoped wrapper that caches each read by source_hint. ChatHandler builds one per request and threads it into the slow-path DataAccessToolInvoker, so the planner's catalog load is reused by describe_source / query_structured instead of re-reading from the catalog DB. Measured live: describe_source 3.5s -> ~2.0s; catalog reads/request ~5 -> ~2. - chat.py: one module-level ChatHandler singleton instead of per-request, keeping the Orchestrator/Chatbot Azure clients (and TLS pools) warm across requests. Does not touch the external query_structured handshake (that is the engine-cache work, DB2). Also logs the principal-review fix tracker (R1-R12, DB1-DB3) in PROGRESS.

[NOTICKET] refactor(catalog): single SAMPLE_LIMIT constant shared across introspection paths
Hoist the per-column sample cap into catalog.introspect.base.SAMPLE_LIMIT so the tabular and DB introspection paths reference one source of truth instead of two separate literals (tabular head(3) + extractor SAMPLE_LIMIT=3) that can drift.
