Subject: [PATCH 1/3] test(ui): add comprehensive tests for PanelUI and
 BootstrapEditorUI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add unit tests for internal UI editor classes:
- PanelUITests: tests for JEngine Panel build configuration UI
- BootstrapEditorUITests: tests for Bootstrap inspector UI

Integration tests (Build All, Build Assets Only with XOR/AES/ChaCha20):
- Marked with [Category("Integration")] for separate execution
- Test real build functionality against active build target

Test infrastructure improvements:
- JEngineTestBase: base class with LogAssert.ignoreFailingMessages
- TestsSetUp: assembly-level setup to disable auto-baking
- AssemblyInfo.cs: InternalsVisibleTo for test assembly access

BuildManager improvements:
- Simplified error filtering with unified IgnoredErrors array
- Added "Bake Ambient Probe" to ignored errors (Unity lighting issue)
- Added "catalog file failed" to ignored errors (YooAsset bug)

Subject: [PATCH 2/3] chore(test): remove redundant TestsSetUp.cs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The SetUpFixture doesn't prevent "Bake Ambient Probe" errors since they
come from Unity's BuildPipeline, not scene creation. JEngineTestBase
already handles error suppression per-test via LogAssert.ignoreFailingMessages.
