- Replaced anchor shorthand syntax with explicit range format (1: -> 1-1:) and removed ^/v sigils in favor of ^A-B repeat and A-B:- delete operations. - Added repeat edit kind to support ^A-B syntax for copying lines A through B, and inline delete syntax A-B:- for range deletions. - Removed after_anchor cursor kind and standalone delete rows; empty anchor blocks now produce blank-line replacements instead of deletions. - Updated parser, tokenizer, and type system to discriminate literal and repeat payloads, and refactored apply/recovery logic to expand repeat edits into individual inserts. - Updated coding-agent test fixtures and settings documentation to reflect new hashline syntax and behavior.
