Close milestone 4 with review evidence

Record the independent reviewer pass that closes the first-run UX/docs milestone and archive the raw readiness report under user-readiness.

Clarify the README quickstart by naming the default Cmd+m/Super+m hotkey, and align the roadmap plus release checklist with the independent-review closeout wording while keeping milestones 2 and 3 open pending manual validation.

Validation: PYTHONPATH=src python3 -m aman --help; PYTHONPATH=src python3 -m unittest tests.test_aman_cli tests.test_config_ui; user-confirmed milestone 4 validation.

+- Reviewer: Independent AI review
+- Date: 2026-03-12

 ## First-run questions or confusions
 
-- Question:

-  - How the docs or product resolved it:
+- Question: Which hotkey am I supposed to press on first run?
+  - Where it appeared: `README.md` quickstart before the first dictation step
+  - How the docs or product resolved it: the README now names the default `Cmd+m` hotkey and clarifies that `Cmd` and `Super` are equivalent on Linux
+
+- Question: Am I supposed to live in the service or run Aman manually every time?
+  - Where it appeared: the transition from the quickstart to the ongoing-use sections
+  - How the docs or product resolved it: the support matrix and `Daily Use and Support` section define `systemd --user` service mode as the default and `aman run` as setup/support only
