### Step 624: Agent Chat Panel model
**Status:** PASS (12/12 tests)
Introduces the core in-editor agent chat model with message history, draft input,
role/timestamp metadata, and a dedicated chat panel surface.
**Files added:**
- `editor/src/AgentChatPanelModel.h` - chat model/state:
- message roles (user/assistant/tool)
- message history storage + draft input
- send/append helpers with trim and auto-scroll behavior
- `editor/src/panels/AgentChatPanel.h` - ImGui chat panel renderer:
- scrollable message history
- multi-line input + send action
- `editor/tests/step624_test.cpp` - 12 tests covering:
- empty/default state behavior
- send validation and draft clearing
- role/timestamp/order correctness
- auto-scroll and role-label mapping
**Files modified:**
- `editor/src/state/AgentState.h` - added `AgentChatState` sub-struct storage
- `editor/src/state/UIFlags.h` - added `showAgentChatPanel` visibility toggle
- `editor/src/panels/MenuBarPanel.h` - view menu toggle for Agent Chat panel
- `editor/src/main.cpp` - panel include + render wiring
- `editor/CMakeLists.txt` - `step624_test` target
**Verification run:**
- `cmake -S editor -B editor/build-native` - PASS
- `cmake --build editor/build-native --target step624_test step623_test` - PASS
- `./editor/build-native/step624_test` - PASS (12/12)
- `./editor/build-native/step623_test` - PASS (8/8) regression coverage
