[NEW][agentj][0.2.0] Add Agent J

Agent J

A phone remote for the AI coding agent running on your Olares.

• Talk to the agent from your phone; it works on this Olares, and risky steps wait for approval on the phone.
• On first start OpenCode is connected to Olares Router and its first ready chat model (no API key for local models).
• Runs from its own multi-arch image (ghcr.io/preangelleo/agentj-olares, pinned by digest): Agent J, OpenCode, uv and
  bubblewrap are preinstalled in a read-only root filesystem, run as uid 1000; nothing is downloaded at start.
• The agent runs inside Agent J's bubblewrap sandbox. The pod uses a user namespace (hostUsers: false) with
  procMount: Unmasked so the sandbox can start without privileged mode or added capabilities. On fs_type: jfs
  both are left off.
• Storage: appData for Agent J's own state, Home/AgentJ for work files. No loginOlaresCLI.
• Requires an Agent J seat (https://agentj.app/account). Setup: open the app, paste the installation prompt from the
  seat card, then add the phone from the account page.

Tested on Olares OS 1.12.7 (amd64, single node): install, setup, phone pairing, message round trip, upgrade and
uninstall with --delete-data; the arm64 image is built and checked (agentj --version, bubblewrap) under emulation.
