feat(minecraft): compact brain prompt tool descriptions to reduce token usage

Browse Source 
Replace verbose JSDoc-style tool formatting with pipe-delimited compact format (name|description|sig:positional|obj:object|args:params), abbreviate common words in descriptions (Automatically→Auto, approximately→approx, coordinate→coord, inventory→inv, nearest→near, number of→#, player→plyr, resource→res, position→pos, whether→if), flatten parameter descriptions from multi-line @param blocks to semic
