* fix: Add timestamp protection for team_state updates

Prevent old messages from overwriting newer team state by checking
team_state_updated_at before updating.

* fix: Extract team tasks from Task/TaskCreate/TaskUpdate tools

- Enhance processTaskToolWithTeam to also generate task entries from
  the Task tool's description field when spawning teammates
- Add processTaskCreate handler for TaskCreate tool calls
- Add processTaskUpdate handler for TaskUpdate tool calls
- Register both new tools in the extraction switch statement

This fixes the gap where the Tasks section in TeamPanel could never
populate because team task data was not being extracted from the
message stream.

* fix: Skip orphan TaskUpdate without title to prevent schema validation failure

When TaskUpdate arrives before TaskCreate (message ordering), skip inserting
incomplete tasks that lack required title field, preventing entire teamState
from being dropped by schema validation.

* test: Add unit tests for orphan TaskUpdate handling

Verify that applyTeamStateDelta correctly skips inserting tasks without
title field (orphan TaskUpdate) while still allowing normal task creation
and updates to existing tasks.
