fix(mindcraft-skills): hard timeout on every skill call

Browse Source 
mc_avoid_enemies (and 7 other tools) wrapped only in safeCall without a
withTimeout. When mindcraft's underlying pathfinder/pvp goal couldn't be
satisfied, the call never resolved — the Pi tick loop blocked forever.
Observed live: mc_avoid_enemies pending >10 minutes after one mc_observe.

safeCall now takes timeoutMs (default 30s) and wraps withTimeout itself,
so every tool gets a hard ceiling. Per-tool overrides:
  - goToPosition / goToNearestBlock: 120s / 90s (unchanged from before)
  - defendSelf / avoidEnemies: 45s
  - stay: secs*1000 + 10s
  - craft / consume / pickup / place: 30s
  - equip: 15s
collectBlock still uses its bespoke per-iter 75s loop.
