### Step 632: Agent task status overlay
**Status:** PASS (12/12 tests)
Adds agent task status visibility in the editor shell:
status bar summary (`[Agent: X running, Y pending]`) and detailed task rows in
the agent chat panel with description, elapsed time, tool-call count, current
step, and per-task cancel action.
**Files added:**
- `editor/src/AgentTaskStatusOverlay.h` - overlay model:
- status summary composition for status bar rendering
- per-task row projection for task-panel rendering
- status text mapping and cancel dispatch helper
- `editor/tests/step632_test.cpp` - 12 tests covering:
- running/pending summary counts and label formatting
- empty-task edge behavior
- task-row projection, elapsed-time computation, and cancelability flags
- tool-call/current-step projection and cancellation semantics
**Files modified:**
- `editor/src/AgentTaskSlots.h` - extended task metadata + helpers:
- start-time-aware slot assignment overload
- progress updates (`toolCallsMade`, `currentStep`)
- elapsed tracking for overlay reporting
- `editor/src/panels/StatusBarPanel.h` - status-bar agent item:
- renders overlay summary when work is active
- click opens the agent chat panel
- `editor/src/panels/AgentChatPanel.h` - task tabs + task list rendering:
- slot tabs for parallel task threads
- detailed task rows with cancel controls
- `editor/CMakeLists.txt` - `step632_test` target
**Verification run:**
- `cmake -S editor -B editor/build-native` - PASS
- `cmake --build editor/build-native --target step632_test step631_test` - PASS
- `./editor/build-native/step632_test` - PASS (12/12)
- `./editor/build-native/step631_test` - PASS (12/12) regression coverage
