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
