v2.14

What's changed

• Bumped package metadata and runtime __version__ to 2.14 so the source archive and a0 --version report the correct CLI version.
• Fixed the model editor to load and save the active preset while preserving untouched models, other presets, and the current selection.
• Added Main Supports Vision and optional Vision sidecar controls matching the Web UI, with Apply/Cancel kept visible while fields scroll.
• Isolated remote terminal sessions by chat so concurrent chats no longer share shell state, input, output, or resets.
• Waited for the connector handshake before reporting readiness on connection and recovery, and clarified handshake timeout errors.
• Kept standalone macOS and Windows Computer Use backends compatible with older released CLI versions.
• Updated multidict to 6.9.1 and recorded minimum aiohttp and anyio security versions in the release dependency inputs.
