feat: live monitor TUI (M2) — 0.21.0

Upgrade `rigdoctor monitor` from a basic redraw to a stdlib curses dashboard
(tui.py): current / session-min / session-max per sensor, grouped by subsystem,
with temperature & utilization color bands (GPU-lost flagged red). q quits,
r resets min/max. Plain full-screen redraw fallback on a non-TTY (--plain forces
it). Pure track()/band() helpers are unit-tested; curses path verified in a pty.

Completes the Monitoring bundle (M2 + M8).

"""Live monitor TUI (M2): a curses HWMonitor-style terminal dashboard.
Shows current / session-min / session-max per sensor, grouped by subsystem, with
temperature and utilization color bands. stdlib `curses` only; falls back to a plain
full-screen redraw when stdout isn't a TTY (piped/SSH-without-tty). Keys: q quit, r reset
the session min/max. The terminal face of the same live data the GUI dashboard graphs.
