Adds native integrations for Gemini CLI, Claude Code, and OpenCode. The Gemini AfterTool extension returns bounded repair context after successful file edits and was exercised through a copied installation on Gemini CLI 0.32.1. Claude Code receives the same bounded guidance through PostToolUse; OpenCode 1.18.27 uses its stable tool.execute.after contract and skips edits without an explicit path. All adapters are non-blocking and never rewrite files.
