🧪 feat: stateful_code_sessions capability for warm Code API sandbox sessions (experimental) (#14150)
* ✨ feat: stateful_code_sessions capability for warm Code API sandbox sessions

Wire the @librechat/agents stateful sandbox sub-config behind a new,
off-by-default stateful_code_sessions agent capability. createRun sets
toolExecution.sandbox.statefulSessions when code execution is active in the
run AND the capability is enabled; execute_code and bash_tool factories get
the param so their descriptions hedge toward persistence. Rides the existing
variable-not-literal runConfig pattern, so it no-ops until @librechat/agents
is bumped to the version shipping the sandbox sub-config.

* ✨ feat: per-agent stateful code sessions (builder toggle + init gating)

Stateful sessions now require the agent's own opt-in, not just the admin
capability. New agent field stateful_code_sessions (schema + validation +
types) surfaces as a toggle in Agent Builder Advanced settings, gated on
the app capability and disabled without Code Interpreter. initializeAgent
resolves the per-agent truth (admin capability AND builder opt-in AND
code env) once: the registered bash_tool description, the execute_code
factory, and createRun's toolExecution.sandbox gate all read the same
resolved value. statefulSessionsAvailable threads through the same call
sites as codeEnvAvailable, including handoff discovery and added convos.

* 🐛 fix: propagate runtime_session_hint to sandbox executor in event-driven tool path

The event-driven ON_TOOL_EXECUTE handler built config.toolCall without the
resolved runtime_session_hint, so BashExecutor/CodeExecutor never sent
runtime_session_hint to the Code API. Every conversation then collapsed onto
the server-derived default session (no per-conversation isolation). Copy
tc.runtimeSessionHint onto toolCallConfig._runtime_session_hint, mirroring the
SDK direct-execution path.

* 🐛 fix: address Codex review findings for stateful code sessions

- OpenAI-compatible service (packages/api/src/agents/openai/service.ts) now
  derives and passes statefulSessionsAvailable alongside codeEnvAvailable, so
  the feature activates on that route (previously statefulCodeSessions resolved
  false there and createRun never sent toolExecution.sandbox).
- Thread runtime_session_hint through the host file-authoring tools
  (create_file/edit_file/read_file): those host branches return before the
  generic tool path, so readSandboxFile/writeSandboxFile now forward the
  per-conversation hint instead of falling back to the Code API default session.
- StatefulSessions builder toggle clears its form value when Code Interpreter is
  disabled, so a saved agent matches the disabled UI and re-enabling code doesn't
  silently reactivate stateful sessions.

* 🐛 fix: normalize stateful_code_sessions on save when Code Interpreter disabled

Addresses Codex review (round 2): a stale `stateful_code_sessions` opt-in
could persist when Code Interpreter (`execute_code`) is disabled from the
main agent builder without opening Advanced settings, silently reactivating
warm sessions if code was later re-enabled.

- AgentPanel: normalize in `composeAgentUpdatePayload` (the always-run save
  path) so `stateful_code_sessions` is forced to `false` whenever
  `execute_code !== true`, regardless of whether Advanced was opened.
- StatefulSessions: revert the mount-scoped useEffect (round-1 approach) —
  it only fired while the Advanced panel was mounted, missing this path.
- Add spec coverage for both branches of the normalization.
