Defenses now work outside combat mode with stamina cost, recovery lock
(based on timing_window_ms), and broadcast to nearby players. Lock
prevents spamming defenses — you commit to the move. Stamina deduction
moved from encounter.defend() to do_defend command layer. Defense
commands registered with mode="*" instead of "combat".
Attacker can change their move mid-telegraph or mid-window without
resetting the timer. Old move's stamina is refunded, new move charged.
Defender gets a fresh telegraph on switch. Feedback says "switch to"
instead of "use" when swapping attacks.
The DREAMBOOK always described "punch right/left [target]" as one command
with a direction argument, but the implementation had separate TOML files
and multi-word command names that the dispatcher couldn't reach (it only
matches the first word). Aliases like "pr" also couldn't pass targets
because the shared handler tried to re-derive the move from args.
Changes:
- Merge punch_left/right, dodge_left/right, parry_high/low into single
TOML files with [variants] sections
- Add command/variant fields to CombatMove for tracking move families
- load_move() now returns list[CombatMove], expanding variants
- Handlers bound to moves via closures at registration time:
variant handler for base commands (punch → parses direction from args),
direct handler for aliases and simple moves (pr → move already known)
- Core logic in do_attack/do_defend takes a resolved move
- Combat doc rewritten as rst with architecture details
- Simplify mud.tin aliases (pr/pl/etc are built-in MUD commands now)
