docs: clarify when to use update_todo_list tool (#5926)

* docs: clarify when to use update_todo_list tool

Added 'complicated' to the condition for when to use the update_todo_list tool,
making it clearer that the tool should be used for tasks that are either
complicated OR involve multiple steps.

* fix: update vscode mock and snapshots for update_todo_list tool changes

- Add missing RelativePattern export to vscode mock
- Fix onDidChangeWorkspaceFolders function in workspace mock
- Update test snapshots to reflect new "complicated" text in update_todo_list tool documentation
- Build tree-sitter WASM files to fix parsing tests

Fixes failing CI tests related to PR #5926 documentation changes.

* Delete package-lock.json

* revert: remove unrelated changes to src/__mocks__/vscode.js
