Mineflayer's collectBlock plugin and pathfinder can hang indefinitely when:
- the requested block name doesn't match anything in range (e.g. asking for
"oak_log" when the only nearby logs are "dark_oak_log"),
- pathfinder cannot reach the goal but doesn't return a clean noPath,
- a path computation enters an infinite-search state in dense terrain.
This blocks the entire Pi tool loop — observed in a live test where
mc_collect_block("oak_log", 4) ran for 8+ minutes without ever returning,
leaving Pi unable to respond to chat or do anything else.
Add a 90s timeout for collectBlock/goToNearestBlock and 120s for goToPosition.
On timeout the tool throws a descriptive error so the agent learns to retry
with a different block name or position rather than waiting forever.
