* Add claude-teams, omo, and __tmux-compat to Go relay CLI
These commands previously only existed in the Swift CLI which uses Unix
domain sockets and can't connect over TCP relay. The Go relay CLI already
handles TCP connections, so adding the commands here makes them work
inside `cmux ssh` sessions.
- `cmux claude-teams`: creates tmux shim scripts, configures environment
(fake TMUX/TMUX_PANE, socket path, workspace/surface IDs), and execs
into `claude --teammate-mode auto`
- `cmux omo`: same pattern for OpenCode with terminal-notifier shim
- `cmux __tmux-compat`: translates tmux commands (split-window,
send-keys, capture-pane, display-message, list-panes, etc.) into cmux
JSON-RPC calls over the relay socket. Includes main-vertical layout
tracking, wait-for signaling, and format string rendering.
* Fix: search original PATH before environment modification
findExecutable was called after configureAgentEnvironment prepended the
shim directory to PATH. The Swift CLI searches the original PATH before
modification. Renamed to findExecutableInPath with explicit PATH arg and
moved the search before configureAgentEnvironment.
* Fix cmux omo hang and port oh-my-opencode plugin setup
Root cause: socketRoundTripV2 had no read timeout. When connecting to a
stale relay port (accepted TCP but never responded), the read blocked
forever. This caused getFocusedContext to hang, blocking agent launch.
Fixes:
- Add 15s read deadline to socketRoundTripV2 (affects all v2 RPC calls)
- Add 5s timeout to getFocusedContext so agent launch proceeds even if
system.identify is slow
- Port omoEnsurePlugin from Swift: creates shadow config dir, adds
oh-my-opencode to plugin list, symlinks node_modules/package.json,
installs plugin via bun/npm if missing, configures tmux settings
(enabled=true, lower min widths), sets OPENCODE_CONFIG_DIR
* Fix: use bun as runtime for node-script opencode when node is missing
opencode is installed via bun as a #!/usr/bin/env node script, but on
some systems (like the macmini) bun is installed without a standalone
node binary. Detect node scripts and fall back to bun as the runtime
since bun is node-compatible.
* Fix subagent pane theme: preserve COLORTERM, keep TERM_PROGRAM
The cmux ssh bootstrap exports COLORTERM=truecolor and TERM_PROGRAM=ghostty.
Our configureAgentEnvironment was unsetting TERM_PROGRAM and not setting
COLORTERM, causing subagent panes (created via split-window) to lose
truecolor detection and render with wrong theme colors.
* Restore TERM_PROGRAM unset, keep COLORTERM=truecolor
* Force dark colorScheme in opencode shadow config for SSH
* Remove hardcoded dark colorScheme, let opencode detect naturally
* Detect system color scheme for opencode over SSH
* Remove color scheme detection workaround, let opencode handle natively
