Adds a new /gsd logs command for browsing and inspecting GSD's existing
logging infrastructure. Users can now discover and review activity logs,
debug logs, and metrics without navigating the filesystem manually.
Subcommands:
/gsd logs — List recent activity + debug logs with metrics summary
/gsd logs <N> — Show summary of activity log #N (tool calls, files, errors)
/gsd logs debug — List debug log files
/gsd logs debug <N> — Show debug log summary (events, duration, errors)
/gsd logs tail [N] — Show last N activity log summaries (default 5)
/gsd logs clear — Remove old activity and debug logs (keeps recent 5)
Addresses #1161 — users needed a way to understand what happened during
auto-mode sessions for debugging.
