ดาวน์โหลด pi 0.63.1

Added
- Added gemini-3.1-pro-preview-customtools model availability for the google-vertex provider (#2610 by @gordonhwc)
Fixed
- Documented tool_call input mutation as supported extension API behavior, clarified that post-mutation inputs are not re-validated, and added regression coverage for executing mutated tool arguments (#2611)
- Fixed repeated compactions dropping messages that were kept by an earlier compaction by re-summarizing from the previous kept boundary and recalculating tokensBefore from the rebuilt session context (#2608)
- Fixed interactive compaction UI updates so ctx.compact() rebuilds the chat through unified compaction events, manual compaction no longer duplicates the summary block, and the trigger-compact example only fires when context usage crosses its threshold (#2617)
- Fixed interactive compaction completion to append a synthetic compaction summary after rebuilding the chat so the latest compaction remains visible at the bottom
- Fixed skill discovery to stop recursing once a directory contains SKILL.md, and to ignore root *.md files in .agents/skills while keeping root markdown skill files supported in ~/.pi/agent/skills, .pi/skills, and package skills/ directories (#2603)
- Fixed edit tool diff rendering for multi-edit operations with large unchanged gaps so distant edits collapse intermediate context instead of dumping the full unchanged middle block
- Fixed edit tool error rendering to avoid repeating the same exact-match failure in both the preview and result blocks
- Fixed auto-compaction overflow recovery for Ollama models when the backend returns explicit prompt too long; exceeded max context length ... errors instead of silently truncating input (#2626)
- Fixed built-in tool overrides that reuse built-in parameter schemas to still honor custom renderCall and renderResult renderers in the interactive TUI, restoring the minimal-mode example (#2595)
