Adds StdinBuffer class (adapted from OpenTUI, MIT license) to split
batched stdin into individual sequences before they reach components.
This fixes key presses being dropped when batched with release events,
which commonly occurs over SSH due to network buffering.
- Each handleInput() call now receives a single event
- matchesKey() and isKeyRelease() work correctly without batching awareness
- Properly buffers incomplete escape sequences across chunks
- Handles bracketed paste mode
Addresses #538
- Enable flag 2 in Kitty protocol for event type reporting
- Add isKeyRelease() and isKeyRepeat() functions
- Parse event type suffix (:1/:2/:3) in Kitty sequences
- Export KeyEventType type
- Add LoginDialogComponent with proper borders (top/bottom DynamicBorder)
- Refactor all OAuth providers to use racing approach (browser callback vs manual paste)
- Add onEscape handler to Input component for cancellation
- Add abortable sleep for GitHub Copilot polling (instant cancel on Escape)
- Show OS-specific click hint (Cmd+click on macOS, Ctrl+click elsewhere)
- Clear content between login phases (fixes GitHub Copilot two-phase flow)
- Use InteractiveMode's showStatus/showError for result messages
- Reorder providers: Anthropic, ChatGPT, GitHub Copilot, Gemini CLI, Antigravity
- Added SymbolKey type with 32 symbol keys
- Added symbol key constants to Key helper (Key.backtick, Key.comma, Key.period, etc.)
- Updated matchesKey() and parseKey() to handle symbol key input
- Added documentation in coding-agent README with examples
* fix(tui): expand paste markers when opening external editor
Add getExpandedText() method to Editor that substitutes paste markers
with actual content. Use it in Ctrl-G external editor flow so users
see full pasted content instead of [paste #N ...] placeholders.
* docs: add changelog entries for #444
