Cover the cold-start legacy-history fallback.
taskHistoryStoreInitialized starts as false, so getTaskHistoryItem can read getGlobalState("taskHistory") before store initialization. The existing missing-file test covers the warm fallback with a legacy item. It does not cover the cold-start case where "taskHistory" is absent. Add a test that keeps the store uninitialized, returns undefined for that key, and asserts that getTaskWithId rejects with "Task not found". The repository convention requires both cold-start and warm fallback cases.

Nice! Thanks you for addressing this, had one question if we could also address existing extension state.

Stops new writes, but the old "taskHistory" blob is still sitting in globalState from before migration. VS Code fires the large-state warning whenever it reads or writes the total extension state, so the warning will keep appearing even after this PR lands. Should initializeTaskHistoryStore (or the migration block in it) also call this.context.globalState.update("taskHistory", undefined) after marking the migration complete?

@PierrunoYT - after reviewing the recent changes, lets revert this request, and instead file a separate ticket for it, it might not be a simple addition for handling old blobs.

Reverts b92f0a3 at the maintainer's request. Clearing the pre-migration globalState "taskHistory" blob needs its own design for handling old blobs, so it will be tracked in a separate issue. This PR stays scoped to stopping new task history writes to globalState. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Assert that no taskHistory write call occurs.
expect.anything() excludes null and undefined, so a call to globalState.update("taskHistory", undefined) passes these assertions. VS Code treats undefined as removing the stored key. (vitest.dev) Check that no recorded call has "taskHistory" as its first argument in either test.
As per path instructions, “Require regression coverage at the lowest valid harness with behavior-focused assertions, including relevant negative, error, false/unset, and boundary cases.”
