Add a pty-mock workspace crate (echo/alt-screen/paste-echo/buffer-fill/
sync-blocks subcommands) plus an in-process integration test suite that
drives Proxy directly via a new_for_test constructor and #[cfg(test)]
state accessors. Sets up the regression net needed before swapping the
underlying VT emulator from vt100 to termwiz.
Pulled from upstream draft PR #35; the alt-screen feed-order semantic
change is intentionally deferred (its dedicated test is left #[ignore]).
* fix: bracketed paste passthrough and pty write deadlock prevention
Enable bracketed paste on the real terminal at startup so tmux/Ghostty
wraps paste content in markers. Detect paste markers in process_input
and forward directly to the child pty, skipping byte-by-byte lookback
matching. Replace blocking write_all with write_to_pty_draining that
interleaves output reads to prevent the classic pty buffer deadlock
when forwarding large input.
* Fix clippy/fmt, buffer drained PTY output through VT parser, handle split paste end markers
- Fix clippy collapsible_if warning and cargo fmt issues
- Drained child output during PTY writes now buffers into pty_drain_buffer
and is processed through process_output after process_input returns,
keeping VT parser state, history, and alt-screen tracking in sync
- Add paste_remainder buffer to handle paste end markers split across
read() boundaries, preventing permanent stuck-in-paste-mode state
- Add split_trailing_marker_prefix helper with tests

* Fix auto-lookback trigger and add version tracking
- Trigger on stdin inactivity instead of render time
- Only dump when new output exists since last dump
- Default timeout 5s -> 15s
- Embed git hash in version output
- Document macOS config path
* feat: add auto lookback mode
Automatically shows full terminal history after idle timeout,
returns to truncated view when new output arrives.
- Add auto_lookback_timeout_ms config option (default: 1000ms)
- Add --auto-lookback-timeout CLI flag
- Set to 0 to disable the feature
* intermediate
* auto lookback
