Rename task CLI from ask to do

- Move cmd/ask to cmd/do; mage BuildDo builds binary named do
- Update askcli help text, errors, Fish completion (complete -c do, __do_*)
- Task alias cache path: XDG cache hexai/do/task-aliases-v2.json
- Refresh README and docs; go install path cmd/do@latest
- Remove accidentally tracked cmd/ask build artifact; ignore cmd/do/do and cmd/do/ask
