Make the X11 user path visible on first contact instead of burying it under config and maintainer detail.
Rewrite the README around the supported quickstart, expected tray and dictation result, install validation, troubleshooting, and linked follow-on docs. Split deep config and developer material into separate docs, add checked-in screenshots plus a short WebM walkthrough, and add a generator so the media assets stay reproducible.
Also fix the CLI discovery gap by letting `aman --help` show the top-level command surface while keeping implicit foreground `run` behavior, and align the settings, help, and about copy with the supported service-plus-diagnostics model.
Validation: `PYTHONPATH=src python3 -m unittest tests.test_aman_cli tests.test_config_ui`; `PYTHONPATH=src python3 -m unittest discover -s tests -p 'test_*.py'`; `python3 -m py_compile src/*.py tests/*.py scripts/generate_docs_media.py`; `PYTHONPATH=src python3 -m aman --help`.
Milestone 4 stays open in the roadmap because `docs/x11-ga/first-run-review-notes.md` still needs a real non-implementer walkthrough.
Implement milestone 2 around a portable X11 release bundle instead of\nkeeping distro packages as the only end-user path.\n\nAdd make/package scripts plus a portable installer helper that builds the\ntarball, creates a user-scoped venv install, manages the user service, handles\nupgrade rollback, and supports uninstall with optional purge.\n\nFlip the end-user docs to the portable bundle, add a dedicated install guide\nand validation matrix, and leave the roadmap milestone open only for the\nremaining manual distro validation evidence.\n\nValidation: python3 -m py_compile src/*.py packaging/portable/portable_installer.py tests/test_portable_bundle.py; PYTHONPATH=src python3 -m unittest tests.test_portable_bundle; PYTHONPATH=src python3 -m unittest tests.test_aman_cli tests.test_diagnostics tests.test_portable_bundle; PYTHONPATH=src python3 -m unittest discover -s tests -p 'test_*.py'
