Task 2 Report: Workbench Types And Project-Scoped Mock Data

What changed

Added the typed workbench domain model in apps/web/src/features/workbench/types.ts.
Added two project records and project-scoped workspace mock data in apps/web/src/features/workbench/mockData.ts.
Added coverage for dynamic projects, project-specific channels, channel ordering, and custom-link URL shape in apps/web/src/features/workbench/mockData.test.ts.
Kept the implementation scoped to the requested workbench data and test files. No UI components, React dependencies, or shadcn/ui dependencies were changed.

Targeted test: npm test -- --run src/features/workbench/mockData.test.ts -> 1 file passed, 2 tests passed.
Full Web test suite: npm test -- --run -> 4 files passed, 7 tests passed.
Web production build: npm run build -> successful.
Formatting/diff validation: git diff --check -> no issues.

Created mockData.test.ts before production implementation.
Ran the targeted test and observed the expected red result: Vitest could not resolve ./mockData because the implementation files did not exist.
Added types.ts and mockData.ts using the exact task brief values.
Re-ran the targeted test and observed green: 2/2 tests passed.
Ran the full Web test suite and build successfully.

ChannelType contains all seven required channel literals in the specified order.
ProjectWorkspace includes all required project-scoped collections.
Both projects receive distinct channel IDs, item IDs, and custom-link URLs through the project ID interpolation.
getProjectWorkspace returns the requested workspace and preserves the brief's fallback to the first workspace for unknown IDs.
The test verifies at least two projects, numeric IDs, names, distinct workspace IDs, channel order, and custom-link URL format.
No unrelated tracked files were changed.

Vitest and Vite report the pre-existing warning that no Svelte config was found in apps/web; it did not prevent tests or the build from succeeding.
The mock data is intentionally static and duplicated across projects via the shared workspace mapper, as required for this MVP task.
