Fix claude --green subprocess stdin raw mode error

When claude --green spawns Claude Code as a subprocess to apply CI fixes,
it was using interactive mode with piped stdin. This caused Ink (Claude's
UI library) to fail when trying to use raw mode on the piped stdin.

Solution: Use --print flag to run Claude in non-interactive mode. This
avoids the raw mode requirement while still allowing Claude to use tools
to make file changes.

Changes:
- Replace runClaude(..., { interactive: true }) with direct call to
  runCommandWithOutput using --print flag
- Add error logging for non-zero exit codes
