Pi 0.13.2

Changed

• Tool output truncation: All tools now enforce consistent truncation limits with actionable notices for the LLM. (#134)
  • Limits: 2000 lines OR 50KB (whichever hits first), never partial lines
  • read: Shows [Showing lines X-Y of Z. Use offset=N to continue]. If first line exceeds 50KB, suggests bash command
  • bash: Tail truncation with temp file. Shows [Showing lines X-Y of Z. Full output: /tmp/...]
  • grep: Pre-truncates match lines to 500 chars. Shows match limit and line truncation notices
  • find/ls: Shows result/entry limit notices
  • TUI displays truncation warnings in yellow at bottom of tool output (visible even when collapsed)
