Implement phase 2.1 (human detection) and 2.2 (notifications):
- Detection scorer computes 0.0-1.0 human likelihood from keystroke
timing variance, special key usage, typing speed, command diversity,
and session duration
- Webhook notifier sends JSON POST to configured endpoints with
deduplication, custom headers, and event filtering
- RecordingChannel gains an event callback for feeding keystrokes
to the scorer without coupling shell and detection packages
- Server wires scorer into session lifecycle with periodic updates
and threshold-based notification triggers
- Web UI shows human score in session tables with highlighting
- New config sections: [detection] and [[notify.webhooks]]

Implement Phase 1.4: replaces the hardcoded banner/timeout stub with a
proper shell system. Adds a Shell interface with weighted registry for
shell selection, a RecordingChannel wrapper (pass-through for now, prep
for Phase 2.3 replay), and a bash-like shell with fake filesystem,
terminal line reader, and command handling (pwd, ls, cd, cat, whoami,
hostname, id, uname, exit). Sessions now log command/output pairs to
the store and record the shell name.
