docs(telemetry): list session create/add_message endpoints + SDK methods (#1943)

[r266-tech]

Source: #1943 (zhoujh01 merger / MDNDDD author 2026-05-09T10:12Z) feat(server): add operation telemetry for session create/add_message/commit APIs wraps session.create, session.add_message, and session.commit HTTP handlers with run_operation so callers can opt in via TelemetryRequest. The "Supported operations" lists in the operation-telemetry guide were not updated to surface the new endpoints / SDK methods.

This PR mirrors the new surface bytewise into both EN and ZH guides:

HTTP API list — added two endpoints alongside the existing commit:

• POST /api/v1/sessions
• POST /api/v1/sessions/{session_id}/messages

(verified at openviking/server/routers/sessions.py lines 72/92 telemetry: TelemetryRequest = False on CreateSessionRequest/AddMessageRequest, lines 114/290 @router.post("") and @router.post("/{session_id}/messages"))

Python SDK list — added two top-level methods alongside the existing commit_session(...):

• create_session(...)
• add_message(...)

(verified at openviking/async_client.py lines 131/170 + openviking/sync_client.py lines 42/75; both accept telemetry: TelemetryRequest = False)

Session.commit(...) (instance method on the Session class) is already listed; Session.add_message() at openviking/client/session.py:38 does not accept a telemetry kwarg and just delegates to client.add_message(...) without it, so it is intentionally not added to the SDK list to avoid misleading users into a non-functional opt-in path on the Session helper.

8 LOC additive (4 EN + 4 ZH bullets), no other content touched.
