Rename task CLI binary from do back to ask

- Move cmd/do to cmd/ask; mage builds and installs ask; Fish completions to ask.fish
- Update askcli help text, errors, executor default label, and Fish script (__ask_*)
- Task alias cache subdirectory under XDG cache: hexai/ask/
- Rename integration test files and helpers; refresh README and docs
- Rename plan-do-uuid-wrapper.md to plan-ask-uuid-wrapper.md
