Jeena 61017da6ba Combine opencode-container and claude-container into a unified agent-container
Merge the two separate container projects into a single image and
management script. Both OpenCode and Claude Code are installed in the
same Arch Linux image and share one persistent $HOME directory, which
enables the opencode-claude-bridge plugin to read Claude CLI credentials
from within OpenCode.

Subcommands: opencode, claude, update, force-cleanup.
