- Introduced a constant `stopWatcherMaxDuration` to limit the lifetime of the stop watcher, preventing potential resource leaks in pathological stream scenarios.
- Updated the `startStopWatcher` function to use a context with a timeout, ensuring the watcher self-terminates after the specified duration.

- Removed the `stopWatchCancel` from the `sseStreamContext` as the watcher now manages its own lifecycle more effectively.
The Tenant.ConversationConfig field was marked deprecated when
CustomAgent (builtin-quick-answer) replaced the per-tenant defaults
path, but the JSONB column, GET/PUT KV handlers, write helpers and
read fall-throughs all stayed wired. This had two concrete failure
modes:
- Input-field.vue silently PUT-ed per-user model picks back into
/tenants/kv/conversation-config, which requires Admin+ — Viewers
and Contributors got a 403 every time they switched chat models.
- The same write also overwrote the tenant-shared default for every
other user, turning a per-user UX into a per-tenant footgun.
Remove the field, the struct, the validate helper, the PUT case and
the two dead Summary helpers in session/helpers.go. KnowledgeSearch
loses its tenant-conversation fallback (one chunk-tool reader); the
global config + hardcoded defaults still cover it. session_agent_qa
already required agents to declare their own rerank_model_id, so no
behaviour change there.
Frontend follows:
- Input-field.vue: per-user 'last selected chat model' moves to
localStorage, no API call.
- AgentEditorModal: defaults for builtin-quick-answer creation now
come from prompt-templates (system/context/rewrite/fallback) and
retrieval-config (top_k / threshold), the two endpoints that
actually own those settings now.
- AgentSettings.vue: orphan settings page with no router/import
referencing it; deleted.
- api/system: getConversationConfig / updateConversationConfig and
the ConversationConfig interface go away.

To diagnose where latency lives between "user hits send" and "first
token appears" we need a single number that can be matched across
the browser console and the server log. Add correlated TTFB markers
keyed by X-Request-ID:
Frontend (streame.ts)
* Generate the X-Request-ID once and reuse it for logging.
* Log request:start when fetchEventSource is invoked, response:headers
when onopen fires, and response:first_answer the first time an SSE
payload with response_type === 'answer' arrives. Filtering by event
type avoids treating session_title / references / tool_call as the
"first token".
Backend (session handler)
* parseQARequest records the wall-clock entry time and logs TTFB:start
with the same X-Request-ID.
* qaRequestContext carries receivedAt through to the stream handler.
* AgentStreamHandler emits a one-shot TTFB:first_answer_chunk log the
first time it observes an AgentFinalAnswerData chunk, so the delta
against TTFB:start is the server's request-in → first-token-out
budget.
The frontend delta minus the backend delta is then attributable to
network + gin middleware, which were previously invisible.
