Adds Terminal.prepareForExit() to disable Kitty protocol and wait for
in-flight release events before fully stopping. This prevents escape
sequences from leaking to the parent shell over slow SSH connections.
Fixes#1204
- Remove height change detection (only width changes trigger full redraw)
- Change clearOnShrink default to false (use PI_CLEAR_ON_SHRINK=1 to enable)
- Fix viewport check to use previousLines.length instead of maxLinesRendered
(prevents false positive redraws when appending lines after content shrunk)
- Add clearOnShrink setting to /settings in coding-agent
- Remove line truncation in custom message component (always show full content)
Added comprehensive bug regression test that demonstrates:
1. The bug scenario (old implementation using startsWith() fails)
2. The fix works (new implementation using includes() passes)
Test covers:
- Terminal without image support scenario (bug trigger)
- Both Kitty and iTerm2 image protocols
- Very long lines (300KB+) matching crash scenario
- Integration with tool execution scenarios
- Negative cases (no false positives)
All 347 tests pass including 12 new bug regression tests.
Changed isImageLine() from using startsWith() to includes() to detect
Kitty and iTerm2 image escape sequences anywhere in a line, not just
at the start. This prevents TUI width checks from failing on lines
containing image data, which could cause crashes when rendering tool
results with images (e.g., when reading image files).
Also added comprehensive test coverage for isImageLine() including:
- Both iTerm2 and Kitty protocols
- Regression tests for long lines and terminals without image support
- Negative cases to ensure no false positives
Fixes crash: 'Rendered line exceeds terminal width' when image
escape sequences appear in output.
- Add alt+b/alt+f as alternative bindings for cursorWordLeft/cursorWordRight
- Add ctrl+d as alternative binding for deleteCharForward
- Fix ctrl+d in custom editor to perform delete when text is present
(previously it was always consumed, even with non-empty input)
Closes#1043

Appended lines were not committed to terminal scrollback because the
renderer used cursor movement (CSI B) and carriage return without
linefeed. This caused earlier content to be overwritten when the
viewport filled up.
Changes:
- For appended lines, emit \r\n to create real scrollback lines
- When target row is below viewport, scroll with \r\n before positioning
- Add PI_TUI_WRITE_LOG env var for debugging raw ANSI output
- Add fullRedraws readonly property to TUI class
- Add viewport-overwrite-repro.ts test script
