- Removed the standalone vim tool and normalized built-in/requested tooling to edit. - Updated session and SDK tool activation to dedupe lowercase names and track edit state via the edit key. - Added vim-mode argument detection and delegated edit rendering/execution into Vim handlers under edit. - Updated Vim step handling to auto-reorder numeric-positioned commands, including cc/C/S/s/i/I/A cases. - Renamed prompt/changelog text and test expectations to reflect edit-only tool naming and usage.
