feat: stream Claude Code output to conv-loop log with [CC] prefix

- Replace subprocess.run(capture_output) with Popen streaming, so each
line of Claude Code output appears in real-time with [CC] prefix
- Add [CC-RESULT] summary (800 chars) after each claude_code action
- Both opening turn and do_turn() now log CC results
