fix: Handle spawn and branch failures gracefully in dispatch cycle

Browse Source 
Wrap agentManager.spawn() in try/catch — on failure, block the task
instead of crashing the entire dispatch cycle. Move phase status update
to after branch creation succeeds — on branch failure, block the phase
and skip task queuing. Fix statement-breakpoint markers in migration
0020 to use separate lines.

7. **Summary propagation** — `completeTask()` reads the completing agent's `result.message` and stores it on the task's `summary` column. Dependent tasks see this summary in `context/tasks/<id>.md` frontmatter.
8. **Approval check** — `completeTask()` checks `requiresApproval` (task-level, then initiative-level)
9. **Approval flow** — If approval required: status → `pending_approval`, emit `task:pending_approval`
10. **Spawn failure** — If `agentManager.spawn()` throws, the task is blocked via `blockTask()` with the error message. The dispatch cycle continues instead of crashing.
