- Replaced legacy `SWAP`, `INS`, and `PASTE` commands with unified `PUT` and `CUT` hunks across parser, grammar, tokenizer, and test suites. - Added support for named registers and span paste operations in clipboard and block execution logic. - Implemented indentation repair and enhanced gap locator formatting for improved patch resilience. - Updated documentation, system prompts, and session analysis scripts to reflect the new syntax and header shapes.
