Adds reference entries for the byte-based query cache memory budget and the idle-expiry TTL (pgdogdev/pgdog#1266), plus SHOW CONFIG table rows.
…lliseconds) Follows the rename in pgdogdev/pgdog#1266: the behaviour is idle expiry (counted from last access), so the option reuses the existing idle-timeout naming and the millisecond unit of the other *_timeout options.

Documents the two
[general]options added in pgdogdev/pgdog#1266:query_cache_memory_limit— byte budget for the query (AST) cache, LRU eviction once the summed entry size exceeds it; complements the count-basedquery_cache_limit.query_cache_idle_timeout— idle timeout in milliseconds; entries not accessed within the window are dropped by the maintenance sweep.Both default to
0(off). Adds reference entries in the general config page (the anchors the code's doc-comments link to) and the two rows in the SHOW CONFIG table.Companion to pgdogdev/pgdog#1266 — should merge together with it (or be closed if that PR is declined).
