fix(todos): rename todos/done to todos/completed in workflows and docs

The CLI (commands.cjs, init.cjs) uses `todos/completed/` but three
workflow files and three FEATURES.md docs referenced `todos/done/`.
This caused completed todos to land in different directories depending
on whether the CLI command or the workflow instructions were followed.

Closes #1438
