Prepare the 1.0.0 GA release surface

Add the repo-side pieces for milestone 5: MIT licensing, real maintainer and forge metadata, a public support doc, 1.0.0 release notes, release-prep tooling, and CI uploads for the full candidate artifact set.

Keep source-tree version surfaces honest by reading the local project version in the CLI and About dialog, and cover the new release-prep plus version-fallback behavior with focused tests.

Document where raw validation evidence belongs, add the GA validation rollup, and archive the latest readiness review. Milestone 5 remains open until the forge release page is published and the milestone 2 and 3 matrices are filled with linked manual evidence.

Validation: PYTHONPATH=src python3 -m unittest discover -s tests -p 'test_*.py'; PYTHONPATH=src python3 -m unittest tests.test_release_prep tests.test_portable_bundle tests.test_aman_cli tests.test_config_ui; python3 -m py_compile src/*.py tests/*.py; PYTHONPATH=src python3 -m aman version
