 - `internal/tui`: terminal CSI parser now emits structured edit actions for insert/delete chars and insert/delete lines, plus forward/back tab cursor actions; output `CSI M` is parsed as delete-lines while input tokenization still keeps X10 mouse payload handling separate.
 - `internal/tui`: terminal CSI parser now emits report actions for DSR `CSI n`, including device-status, cursor-position, and private-mode unknown reports.
 - `internal/tui`: terminal sequence dispatcher and parser now classify DCS/APC/PM/SOS string-control sequences as `stringControl` actions with payload, terminator, and incomplete-flush state while keeping visible text extraction free of those invisible payloads.
-- `internal/tui`: terminal CSI parser now recognizes DEC X10, highlight, UTF-8, and urxvt numeric mouse modes (`?9h/l`, `?1001h/l`, `?1005h/l`, `?1015h/l`) as mouse-tracking mode actions.
