Add a standalone checksum-verifying installer for the latest published release and a concise README with an executable example, detailed reference links and the shared twelve-component stack overview. Retain the complete versioned installation for rollback and refuse a damaged existing installation.

Validation: just check, just test, mdBook, eleven private installer controls, actual published Linux archive version and retained ONNX bundle. Fixtures use private prefixes and include checksum, missing-asset and unsupported-platform refusals. No new release, host installation or runtime activation; repository-pendant availability remains conditional on verified public assets.

Current integration: b7045913 includes current main. The current main logo/table and reference content are preserved. The README source witness was refreshed; other defining-file hashes and semantic records are unchanged. A published integration commit was merged normally without changing the tested tree.

The installer, installer fixture tests and installer workflow are byte-identical to the prior proposal head. 11 private installer controls pass with the HOME guard clean. The whole proposal inverse restores the entire recorded base tree. Fresh current-head CI is pending; no approval or merge is claimed.
