Four targeted fixes for issues observed during the live autonomous test:
1. **bot.modes shim** (extensions/lib/mcdata.js)
Mindcraft skills.* call bot.modes.pause('cowardice') in 7+ places.
`mineflayer-modes` does not exist on npm — it's internal to Mindcraft.
attachPluginsAndInit now installs a no-op shim so skills.stay() /
.consume() / .defendSelf() etc. stop crashing with "pause undefined".
2. **Death + respawn handlers** (extensions/mineflayer-bridge.ts)
Subscribe to bot 'death' event: append diary line with position,
clear current-task.json so Pi doesn't resume a stale task referencing
inventory that no longer exists.
On 'spawn' within 5s of death: log the new respawn position to diary.
Live test had bot killed twice by zombies at night; the next Pi
prompt was unable to recover. With this it's now an explicit diary
line + clean task slate.
3. **Auto-defend reflex tick** (extensions/mineflayer-bridge.ts)
New setInterval(2s) that, when bot.health < 18 AND a hostile mob
(zombie/skeleton/creeper/spider/etc.) is within 6 blocks AND no
active world task, fires `bot.pvp.attack(nearest)` in the background.
No LLM call needed for instant self-defense — saves tokens and reacts
on mineflayer timescale (sub-second) rather than Pi loop timescale
(~10s+ to reason and dispatch). Throttled to once per 4s.
4. **mc_collect_block bulk rework** (extensions/mindcraft-skills.ts)
Live test showed count=1 succeeds in ~25s but count=8 hangs past
270s with identical blocks in range. Upstream collectBlock plugin
appears to drift on its block cache after the first dig in dense
terrain. Loop single-block collects in-tool instead (75s per iter,
re-pathfind on each iteration). Track per-iter success/failure,
abort after 3 consecutive failures, return aggregate count to the
agent so it can adapt instead of seeing a single failure.
Smoke test: both extensions load, bot connects, perception confirms
hostiles nearby and daylight safety check. No syntax/runtime errors.
