Subject: [PATCH 1/5] fix(rulez_ui): fix 21 failing Playwright E2E tests with
 data-testid selectors

Add data-testid attributes to React components for reliable test selectors:
- EventForm: event-type-select, tool-input, command-input, path-input, simulate-button
- FileTabBar: file-tab-bar, file-tab-{filename}, close-tab-{filename}
- EditorToolbar: editor-toolbar
- Sidebar: sidebar, sidebar-{section}-file-{filename}

Update test files to use data-testid selectors instead of fragile CSS class
and text matching that caused strict mode violations.

Update page objects with new selector patterns for better test maintainability.

All 56 E2E tests now pass on both Chromium and WebKit.

Subject: [PATCH 2/5] fix: exclude rulez_ui/src-tauri from workspace to enable
 Tauri builds

The Tauri project was incorrectly detected as part of the CCH workspace,
causing cargo metadata errors when running tauri build/dev commands.

Adding rulez_ui/src-tauri to workspace.exclude allows the Tauri app
to build independently while keeping the CCH CLI in the main workspace.
