teknium1 eb8960fead fix(api_server): keep one memory provider per session across requests (#120116)
The api_server platform builds a fresh AIAgent per request (per-request
callbacks, model route, ephemeral prompt), so the memory provider was
re-initialised on every request. External providers deliver recall as the
PREVIOUS turn's background prefetch held on the provider instance, so a
continued session (X-Hermes-Session-Id, previous_response_id, declared
session key) never received automatic recall, and for hindsight
local_embedded each init also restarted the embedded daemon, killing the
retain still in flight. Pre-existing: the same probe fails on main before
the hindsight catalog migration (526d135a96, bundled provider).

ApiServerMemorySessions parks the session's initialised MemoryManager
between requests (exclusive check-out/check-in, keyed by profile home +
session id, LRU/idle eviction under the owning profile's scope) and
AIAgent(memory_manager=...) adopts it instead of loading and initialising
the provider again. /v1/chat/completions, /v1/responses, session chat and
/v1/runs all go through the same two seams (_create_agent, turn finally).
