Stable mobile keyboard replacement

What's Changed

• Replace the native keyboard with special keys below the composer while preserving terminal geometry.
• Return with ABC or dismiss the keyboard; keep symbol categories open after input.
• Remove the extra keyboard gap and protect bottom controls from rounded display corners.

Release integrity

Native archives have matching platform-specific SPDX SBOM assets plus GitHub build-provenance and SBOM attestations. Installers and the built-in updater additionally verify a signed manifest and all packaged-file hashes.
