* feat: allow client-side tools to be specified in request
Add `client_tools` field to LettaRequest to allow passing tool schemas
at message creation time without requiring server-side registration.
When the agent calls a client-side tool, execution pauses with
stop_reason=requires_approval for the client to provide tool returns.
- Add ClientToolSchema class for request-level tool schemas
- Merge client tools with agent tools in _get_valid_tools()
- Treat client-side tool calls as requiring approval
- Add integration tests for client-side tools flow

* test: add comprehensive end-to-end test for client-side tools
Update integration test to verify the complete flow:
- Agent calls client-side tool and pauses
- Client provides tool return with secret code
- Agent processes and responds
- User asks about the code, agent recalls it
- Validate full conversation history makes sense

* fix: add client_tools parameter to LettaAgentV2 for API compatibility
V2 agent doesn't use client_tools but needs the parameter
to match the base class signature.

* revert: remove client_tools from LettaRequestConfig
Client-side tools don't work with background jobs since
there's no client present to provide tool returns.

* Fix agent loop continuing after cancellation in letta_agent_v3
Bug: When a run is cancelled, _check_run_cancellation() sets
self.should_continue=False and returns early from _step(), but the outer
for loop (line 245) continues to the next iteration, executing subsequent
steps even though cancellation was requested.
Symptom: User hits cancel during step 1, backend marks run as cancelled,
but agent continues executing steps 2, 3, etc.
Root cause: After the 'async for chunk in response' loop completes (line 255),
there was no check of self.should_continue before continuing to the next
iteration of the outer step loop.
Fix: Added 'if not self.should_continue: break' check after the inner loop
to exit the outer step loop when cancellation is detected. This makes v3
consistent with v2 which already had this check (line 306-307).
