Codescribe 33a5480072 Add log tail command for live log streaming ...

This commit adds a new `ctrld log tail` subcommand that streams
runtime debug logs to the terminal in real-time, similar to `tail -f`.

Changes:
- log_writer.go: Add Subscribe/tailLastLines for fan-out to tail clients
- control_server.go: Add /log/tail endpoint with streaming response
  - Internal logging: subscribes to logWriter for live data
  - File-based logging: polls log file for new data (200ms interval)
  - Sends last N lines as initial context on connect
- commands.go: Add `log tail` cobra subcommand with --lines/-n flag
- control_client.go: Add postStream() with no timeout for long-lived connections

Usage:
  sudo ctrld log tail          # shows last 10 lines then follows
  sudo ctrld log tail -n 50    # shows last 50 lines then follows
  Ctrl+C to stop
