feat(editor): add paredit editor, a terminal-native text editing session - #143
Merged
Conversation
paredit-feature-editor owns the text-buffer aggregate, cursor invariants, editing actions, and undo/redo session state behind a DocumentStore port; the presentation layer adds a thin raw-mode terminal adapter (paredit editor <file>) that translates keypresses into the feature's application API and renders the returned state. Also fixes two defects found while landing this branch: a non- exhaustive Key::Ctrl match that made the workspace fail to compile, and a dead Key::Quit variant that left Ctrl-C/Ctrl-Q/Escape wired to nothing, so the editor had no interactive way to quit.
readme_contract::readme_commands_match_top_level_help caught the drift: `paredit editor` exists in --help but was missing from the README table.

Minor release: `paredit editor <file>` is a new interactive terminal editor command (#143); `paredit edit format`/`paredit fix` also align Common Lisp and Emacs Lisp indentation with Emacs/SLIME conventions across 36 divergence patterns (#144). No removed or renamed stable surface — the capabilities catalog diff against v1.5.0 is purely additive (the new `editor` command only).
