BREAKING: 3-tier split step 2 + engine-bridge v3 EgBim lambdas wired

Completes the Generic / HmEG-aware / App-specific separation started in
f6b6e74. The legacy EgPlugin / EngineBridge / EngineBridge.Client /
EngineBridge.Probe modules are moved into their proper tiers, namespaces
and csproj/sln entries are renamed, and the HmegDirectStateProvider
lambdas are finally populated with real handles from the EgBim plugin
host. A new Recordingtest.Architecture.Tests project enforces the tier
rule at build time.

Moves (git mv + csproj/RootNamespace/AssemblyName rename + sln):

  src/Recordingtest.EgPlugin
    -> src/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost
  src/Recordingtest.EngineBridge
    -> src/Hmeg/Recordingtest.Hmeg.Catalog
  src/Recordingtest.EngineBridge.Client
    -> src/Hmeg/Recordingtest.Hmeg.Bridge.Client
  src/Recordingtest.EngineBridge.Probe
    -> src/Hmeg/Recordingtest.Hmeg.Catalog.Probe

  tests/Recordingtest.EgPlugin.Tests
    -> tests/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost.Tests
  tests/Recordingtest.EngineBridge.Tests
    -> tests/Hmeg/Recordingtest.Hmeg.Catalog.Tests
  tests/Recordingtest.EngineBridge.IntegrationTests
    -> tests/Hmeg/Recordingtest.Hmeg.Catalog.IntegrationTests

Namespace rename applied across all .cs files and csproj RootNamespace:

  Recordingtest.EgPlugin           -> Recordingtest.Sut.EgBim.PluginHost
  Recordingtest.EngineBridge       -> Recordingtest.Hmeg.Catalog
  Recordingtest.EngineBridge.Client -> Recordingtest.Hmeg.Bridge.Client
  Recordingtest.EngineBridge.Probe -> Recordingtest.Hmeg.Catalog.Probe

New: tests/Recordingtest.Architecture.Tests/

  DependencyGraphTests walks Assembly.GetReferencedAssemblies() for each
  tier and fails if a forbidden reference leaks in:
    - Generic modules must not reference HmEG or any app-specific DLL
    - HmEG-aware modules must not reference app-specific DLLs
    - Recordingtest.Hmeg.Bridge must reference HmEG (positive check)
  11 tests, all passing. Prevents future drift from CLAUDE.md §8.1.

Engine-bridge v3 wire-up (HmEgBridgePlugin.BuildProvider):

  Previously the HmegDirectStateProvider lambdas returned null and the
  chain fell through to reflection. They now call directly into the
  EditorPlugin base class that HmEgBridgePlugin inherits:

    spaceProvider    = () => RootSpace
                           // AppManager.ViewportManager.RootSpace
    viewportProvider = () => View
                           // EGViewport : Control, HmEGViewport
    documentPathProvider = () => AppManager?.FileManager?.CurrentFile

  Every lambda is wrapped in try/catch so plugin construction still
  cannot throw back into the SUT. Editor02.HmEGAppManager.dll added as
  a reference on Recordingtest.Sut.EgBim.PluginHost.csproj — app-
  specific tier, which is allowed by the architecture tests.

Entry points were confirmed from read-only review of the SUT sources at
  D:\GiteaAll\EG-BIM_Modeler\EditorPluginInterface\EditorPlugin.cs
  D:\GiteaAll\EG-BIM_Modeler\HmEGApplicationManagementLibrary\HmEGAppManager.cs
  D:\GiteaAll\EG-BIM_Modeler\HmEGApplicationManagementLibrary\SubManager\FileManager.cs

closing out Q1/Q2/Q6/Q7 from docs/hmeg-api-survey.md.

Tests: 115 -> 126 (+11 Architecture), 0 failures.

Next step: live verification of /scene /camera /selection with a real
SUT session; any discrepancy in HmegDirectStateProvider reflection will
be tightened after observing real HmEG camera field names.

-- **3-tier 분리 (incremental, 1단계 완료, 2단계 대기)**
-  - 1단계 ✅: 새 계층 모듈 신설 (`Recordingtest.Bridge.Abstractions`, `Recordingtest.Hmeg.Bridge`, 테스트), 인터페이스 추출, EgPlugin이 HmEG-aware provider chain 사용. 115 tests green. commit pending.
-  - 2단계 ⏳: 기존 `Recordingtest.EgPlugin` → `src/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost` + `.Adapter` 폴더/네임스페이스 이동, `Recordingtest.EngineBridge` → `src/Hmeg/Recordingtest.Hmeg.Catalog`, `Recordingtest.EngineBridge.Client` 분할, ArchitectureTests. 다음 세션 작업.
-- **engine-bridge v3 라이브 검증** — 1단계 wire-up 완료 후 EgBim adapter에서 Space/Viewport 람다 실 매핑 (Q1~Q7 답 필요). 사용자 환경에서 `curl /scene /camera /selection`.
+- **engine-bridge v3 라이브 검증 대기** — 코드 쪽은 완료 (`EditorPlugin.RootSpace`/`View`/`AppManager.FileManager.CurrentFile` 실 매핑). 사용자 환경에서 `curl /scene /camera /selection`로 실값 확인 필요.
