engine-bridge v3 live: /scene /camera /selection all real (#10)

Live end-to-end verification against EG-BIM Modeler succeeded on the
second attempt:

  /health    -> {"status":"ok","port":38080}
  /scene     -> {"object_count":4,"document_path":"NewSpace0"}
  /camera    -> {"eye":[192.97,-328.52,170.72],
                 "target":[33.03,-72.61,10.78],
                 "up":[0,0,1],"fov":45}
  /selection -> {"selected_ids":["ac0380a2-...","d9a287ee-..."]}

1st attempt returned default-zero camera. Root cause: the viewport lambda
used EditorPlugin.View, which is only populated when the plugin is
actually Run() by a user trigger; our bridge plugin just boots an HTTP
server from its constructor and never runs a command, so View stayed
null. Space access worked because RootSpace goes through AppManager,
which is populated for the whole app.

Fix (HmEgBridgePlugin.BuildProvider):

  Before: viewportProvider = () => View;
  After:  viewportProvider = () => {
              var vm = AppManager?.ViewportManager;
              if (vm is null) return null;
              return vm.FocusedViewport ?? vm.Viewports.FirstOrDefault();
          };

Confirmed against read-only view of
  HmEGApplicationManagementLibrary/SubManager/ViewportManager.cs
which exposes FocusedViewport and Viewports. EGViewport : HmEGViewport
so the lambda matches the Func<HmEGViewport?> contract directly.

Plus: scripts/deploy-egbim-plugin.bat for one-click deploy. Checks for
a running SUT, builds Debug, purges the legacy Recordingtest.EgPlugin
folder, cleans the destination, copies 3 DLLs (+ PDBs) into
  EG-BIM Modeler/Plugins/Recordingtest.Sut.EgBim.PluginHost/
and prints the curl commands for verification. HmEG.dll and the
Editor*.dll assemblies are deliberately NOT copied — the SUT already
supplies them.

PROGRESS.md: engine-bridge v3 row finalized; the long-running "라이브
검증 대기" item is done. PLAN.md P1 advances to the Runner <-> sidecar
integration (snapshot /scene /camera /selection at scenario end and
include in the golden baseline).

Follow-up (noted in history): document_path returned "NewSpace0" for
an unsaved scratch document — need to retest with a saved .hmeg file
to confirm the real FileManager.CurrentFile round-trip.

Ref: #10 follow-up, engine-bridge-v3 contract DoD D7 satisfied.

+```
+
+이것이 곧 golden-file 회귀 테스트의 결정성 신호 축이 된다.
+
+## 과정
+
+### 1. 배포 스크립트 `scripts/deploy-egbim-plugin.bat`
+
+사용자가 더블클릭 한 번에 빌드→복사 가능하도록:
+1. `EG-BIM Modeler.exe` 실행 여부 체크 (DLL 잠금 방지)
+2. `dotnet build` Debug
+3. 기존 `Plugins/Recordingtest.EgPlugin/` (legacy) + 기존 `Plugins/Recordingtest.Sut.EgBim.PluginHost/` 삭제
+4. 3개 DLL(+PDB) 복사:
+   - `Recordingtest.Sut.EgBim.PluginHost.dll` (App-specific)
+   - `Recordingtest.Hmeg.Bridge.dll` (HmEG-aware)
+   - `Recordingtest.Bridge.Abstractions.dll` (Generic)
+5. 배포 목록 + curl 명령 안내
+
+`HmEG.dll` / `Editor*.dll`은 SUT에 이미 있으므로 복사 안 함.
+
+### 2. 1차 라이브 결과 (camera 실패)
+
+```
+/scene    → object_count=4 ✅
+/camera   → eye/target/up 전부 (0,0,0) ❌
+/selection → 2 GUID ✅
+```
+
+`/scene` 이 작동했으므로 `AppManager.ViewportManager.RootSpace` 경로는 OK. 즉 `spaceProvider` 정상.
+
+`/camera` 는 default fallback. 원인: `HmEgBridgePlugin`의 `viewportProvider = () => this.View`에서 `View`가 항상 null.
+
+### 3. 원인 분석
+
+`EditorPlugin.View` 는 **플러그인이 `Run()` 될 때만 주입**되는 값. 우리 bridge plugin은 constructor에서 HTTP server만 돌리고 MEF trigger로 실행되지 않으므로 `View` 세터가 한 번도 호출되지 않음.
+
+반면 `AppManager` 는 `TriggerStateService.AppManager` 를 통해 얻어지며 SUT 전역 상태라 즉시 접근 가능. 그래서 `RootSpace` 는 동작하지만 `View` 만 null이었던 것.
+
+### 4. Fix — ViewportManager.FocusedViewport 경유
+
+`D:\GiteaAll\EG-BIM_Modeler\HmEGApplicationManagementLibrary\SubManager\ViewportManager.cs` (read-only) 확인:
+
+```csharp
+public HashSet<EGViewport> Viewports { get; set; }
+public EGViewport FocusedViewport { get; ... }
+public ObservableCollection<HmModel> SelectedModels { get; ... }
+```
+
+`FocusedViewport` 는 활성 뷰포트를 직접 노출. `viewportProvider` 를 다음으로 교체:
+
+```csharp
+var vm = AppManager?.ViewportManager;
+if (vm is null) return null;
+var focused = vm.FocusedViewport;
+if (focused is not null) return focused;
+foreach (var v in vm.Viewports) if (v is not null) return v;
+return null;
+```
+
+### 5. 2차 라이브 결과 — 전부 성공
+
+재빌드 → 배포 → SUT 재실행 → curl:
+- `/camera` eye/target/up 실 좌표
+- `fov=45` (PerspectiveCameraCore 기본값이 45라 실값인지 fallback인지 구분 안 되지만 reflection이 Position/LookDirection/UpDirection에서 성공한 이상 FieldOfView 도 동일 경로로 성공했다고 판단)
+- `/selection` 2 GUID 유지
+- `/scene` object_count=4 유지
+
+### 6. 부수 관찰
+
+- `document_path="NewSpace0"` — `FileManager.CurrentFile` 이 빈 파일에 대해 Space 이름을 반환하는 듯. 저장된 `.hmeg` 파일일 때 진짜 경로 확인 필요 (follow-up).
+- `HmegDirectStateProvider` 의 Selection walk (Space.Children 재귀 + `ISelectable.IsSelected`) 가 잘 동작. 대안 `ViewportManager.SelectedModels` 로 단순화 가능하나 현재 walk 방식이 결정적이고 테스트 친화적이라 그대로 유지.
+
+## 남은 것 (다음 단계 P1)
+
+- **Runner ↔ engine-bridge sidecar 연결** — 시나리오 재생 종료 시점에 `/scene` `/camera` `/selection` 한 번 더 호출해 sidecar JSON으로 베이스라인에 포함. `.received.json` 정규화 규칙 추가. 이게 진짜 golden-file 회귀 파이프라인의 마지막 조각.
+- `document_path` 의 unsaved vs saved 문서 케이스 확인
+- (선택) `SelectionManager.SelectedModels` 직접 사용 옵션 비교
+
+## 관련
+
+- `src/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost/HmEgBridgePlugin.cs` (viewportProvider 교체)
+- `scripts/deploy-egbim-plugin.bat` (신규 — 배포 자동화)
+- `src/Hmeg/Recordingtest.Hmeg.Bridge/HmegDirectStateProvider.cs` (reflection 그대로 재사용)
+- `docs/hmeg-api-survey.md` (Q1~Q7 완성)
