vimsheet.controller.edit_handler

Unified line editor — vi-style editing shared by cells, commands, search.

The editor owns the buffer, the insert/normal sub-modes and the vi motions. Mode-specific behaviour is delegated to an EditorContext (see editor_context.py):

• cell content — \, =, <, >, |, A, I, C, S, r, cw, cc, e, E,

• colon commands — :,

• search prompts — / and ?.

Esc in the insert sub-mode drops back to the normal sub-mode. From the normal sub-mode, Enter commits and Esc either commits (cells) or cancels (commands/search) — see EditorContext.normal_escape.
