Fix shell launch restart loop with persistent interactive shell

[jancurn]

Summary

Fixes a restart loop when launching commands via the ?launch= parameter by wrapping the command in a persistent interactive shell. Previously, commands would exit immediately after completion, causing ttyd to respawn the process repeatedly. Now the shell stays alive after command execution, keeping output visible on screen.

Key Changes

• Shell launch wrapper redesign: Replaced simple command execution with a multi-step wrapper that:

  • Sources the sandbox rcfile for consistent environment and tool wrappers
  • Echoes the command to show what's being executed (like a typed prompt)
  • Captures and displays non-zero exit status
  • Execs an interactive shell to keep the terminal alive after command completion

• Simplified launch parameter syntax: Updated actor.json templates to use the cleaner ?launch=<cmd> form instead of manually constructing ?arg=-c&arg=... parameters

• Tool auto-approval configuration:

  • Added Claude Code wrapper function to pass --dangerously-skip-permissions flag
  • Pre-accepted Claude Code onboarding to skip first-run dialogs
  • Configured Codex CLI auto-approval via config.toml
  • Added OpenClaw tool execution policy and exec-approvals.json

• Shell environment improvements:

  • Changed prompt username from "apify" to "actor"
  • Added guard to prevent welcome message from displaying twice (since rcfile is sourced twice in the launch wrapper)
  • Added comprehensive comments explaining the launch wrapper behavior and tool approval strategy

• OpenCode configuration: Simplified permission model from granular per-tool settings to a single "allow" policy

Implementation Details

The new buildLaunchCommand() function constructs a bash command string that:

1. Sources /app/sandbox_bashrc to set up environment and tool wrappers
2. Echoes the command with a $ prompt prefix for visibility
3. Executes the command with || echo "[command exited with status $?]" to surface failures
4. Execs an interactive bash shell to maintain the terminal session

This approach prevents the restart loop while maintaining a seamless user experience where commands appear to run interactively and any errors remain visible.
