Clarify the current release channels versus the X11 GA target so the project has an explicit support promise before milestone 2 delivery work begins.
Update the README, persona and distribution docs, and release checklist with a support matrix, the systemd --user daily-use path, the manual aman run support path, and the canonical recovery sequence. Mark milestone 1 complete in the roadmap once that contract is documented.
Align run, doctor, and self-check help text with the same service and diagnostics language without changing command behavior.
Validated with PYTHONPATH=src python3 -m aman --help, PYTHONPATH=src python3 -m aman doctor --help, and PYTHONPATH=src python3 -m aman self-check --help. Excludes generated src/aman.egg-info and prior user-readiness notes.
