- main: when the environment's locale is not UTF-8 (LANG unset, C/POSIX),
switch LC_CTYPE to a UTF-8 locale so ncurses delivers and draws
multibyte characters instead of dropping them.
- Buffer::Id(): a process-unique id that survives moves and is fresh for
copies. The terminal renderer's skip and cursor caches and the reload
confirmation now key on it rather than the buffer's address, which is
reused after a buffer is closed.
- The reload confirmation is cancelled by any other command, like the
quit confirmation.
- TerminalFrontend redraws when a deferred open starts a prompt or sets a
status (e.g. the swap recovery question), not only when a buffer opens.

- OpenFromFile builds the new content in a separate PieceTable and
swaps it in only when complete. A reload that ran out of memory used
to leave the buffer empty (filename, journal and dirty state intact),
and the next save truncated the file.
- Editor::ProcessPendingOpens catches exceptions from opening (it runs
in every frontend's loop, outside command dispatch, so bad_alloc on a
huge file ended the editor); the terminal draw is guarded too.
- The hard-link save copy uses a unique mkstemp name, so a leftover
copy no longer blocks every later save; if no copy can be created the
file is still written in place.
- When no temp file can be created in the directory (file writable,
directory not), an existing regular file is written in place instead
of the save failing.

- kte refuses to start when stdin is not a terminal: piped bytes were
executed as editor commands (C-k s plus a path writes a file), and
after EOF the loop spun at full CPU with no way to quit.
- The terminal frontend handles all pending input before drawing (a
paste used to cost a frame and a full redraw per character) and
redraws only after input, a resize or deferred opens, else once a
second. The renderer caches, per row and buffer version, where the
horizontally scrolled part of a line starts and the cursor's render
column, instead of rescanning the line every frame. Idle CPU with the
cursor at the end of a 20 MB line: one full core -> ~1%.
- Buffers with a virtual name (+HELP+) are not journaled and saving one
asks for a file name; it used to write ./+HELP+ and journal under
that path.
- Yank with a repeat count is capped at 256 MiB in total instead of
reserving count x size bytes (C-u 1000000 C-y of a large kill).
- Remove an overload clang reports as unused (-Werror on macOS).

set_escdelay is an ncurses function, not a macro, so the #ifdef guard
compiled it out and ESC waited the 1 s default. KEY_RESIZE was mapped
to Refresh, the C-g cancel handler, which cleared the mark and
cancelled open prompts (including swap recovery) on every resize.
Audit findings B1, B2.

- Added detailed journaling system (`SwapManager`) for crash recovery, including edit recording and replay.
- Integrated recovery prompts for handling swap files during file open flows.
- Implemented swap file cleanup, checkpointing, and compaction mechanisms.
- Added extensive unit tests for swap-related behaviors such as recovery prompts, file pruning, and corruption handling.
- Updated CMake to include new test files.
- Created `piece-table-migration.md` outlining the steps to transition from GapBuffer to a unified PieceTable architecture.
- Included phased approach: extending PieceTable, Buffer adapter layer, command updates, and renderer changes.
- Detailed API changes, file updates, testing strategy, risk assessment, and timeline for each migration phase.
- Document serves as a reference for architecture goals and implementation details.
- Add visual file picker for GUI with toggle support.
- Introduce `GUIConfig` class for loading GUI settings from configuration file.
- Refactor window initialization to support dynamic sizing based on configuration.
- Add macOS-specific handling for fullscreen behavior.
- Improve header inclusion order and minor code cleanup.
