Add timestamp behavior E2E tests and verify bug is fixed

WHAT:
- Added initializeAgent() and clearAgentAttention() methods to DaemonClient
  (packages/server/src/server/test-utils/daemon-client.ts:268-304)
- Added E2E tests for timestamp behavior
  (packages/server/src/server/daemon.e2e.test.ts:482-570):
  - "opening agent without interaction does not update timestamp"
  - "sending message DOES update timestamp"

RESULT:
Bug verified as already fixed in commit 32e111e (Dec 2, 2025) which removed
timestamp thrashing - previously lastActivityAt/updatedAt was updated on
every agent_stream event (15+ times/second during streaming).

Server only sets agent.updatedAt in:
- recordUserMessage (agent-manager.ts:436)
- handleStreamEvent (agent-manager.ts:864)
NOT in clearAgentAttention or initializeAgent flows.

EVIDENCE:
- npm run test --workspace=@paseo/server -- daemon.e2e.test.ts -t "timestamp"
  (2 passed in 9.08s)
- Playwright test showed agent stayed in position 4 with unchanged timestamp
  after clicking

+- [ ] **Test**: Add daemon E2E test for `cancelAgent()`.
+
+  Cancel an agent mid-execution and verify it stops properly.
+
+  **Test case**:
+  1. Create Codex agent
+  2. Send prompt that triggers a long-running operation (e.g., "Run: sleep 30")
+  3. Wait for tool call to start (status: "running")
+  4. Call `cancelAgent(agentId)`
+  5. Verify agent reaches idle or error state within 2 seconds
+  6. Verify no zombie processes left
+
+  **Acceptance criteria**:
+  - Test passes
+  - Agent stops within reasonable time after cancel
+  - DaemonClient `cancelAgent()` method verified working
+
+- [ ] **Test**: Add daemon E2E test for `setAgentMode()`.
+
+  Switch agent mode and verify it takes effect.
+
+  **Test case**:
+  1. Create Codex agent (default mode)
+  2. Verify initial mode in agent state
+  3. Call `setAgentMode(agentId, "plan")` or another valid mode
+  4. Verify mode change reflected in next `agent_state`
+  5. Send a message and verify agent behaves according to new mode
+
+  **Acceptance criteria**:
+  - Test passes
+  - Mode switch persists across messages
+  - DaemonClient `setAgentMode()` method verified working
+
+- [ ] **Test**: Add daemon E2E test for `listAgents()`.
+
+  Verify session state returns current agents.
+
+  **Test case**:
+  1. Connect client
+  2. Create 2 agents
+  3. Call `listAgents()`
+  4. Verify both agents returned with correct IDs and states
+  5. Delete one agent
+  6. Call `listAgents()` again
+  7. Verify only remaining agent returned
+
+  **Acceptance criteria**:
+  - Test passes
+  - Agent list accurate after create/delete operations
+  - DaemonClient `listAgents()` method verified working
+
+- [ ] **Investigate**: Claude provider permissions don't work in daemon E2E tests.
+
+  **Problem**: Claude permission tests are skipped because Claude SDK doesn't request permissions in daemon context. Direct `claude-agent.test.ts` tests pass, but daemon E2E tests don't.
+
+  **Investigation**:
+  1. Compare how permissions work in `claude-agent.test.ts` vs `daemon.e2e.test.ts`
+  2. Check if daemon context affects Claude SDK permission handling
+  3. Check if the issue is in DaemonClient, session setup, or Claude provider
+  4. Add debug logging to trace permission request flow
+
+  **Goal**: Unskip Claude permission tests and achieve parity with Codex.
+
+  **Acceptance criteria**:
+  - Root cause identified and documented
+  - Claude permission tests pass (or clear explanation of why they can't)
