Undo/redo: - cmd_newline recorded the undo node's position after the cursor moved past the split point, so undoing Enter joined the wrong pair of lines. - Backspace/Delete line-joins recorded UndoType::Newline, whose apply() semantics are inverted for a join (forward=split); add UndoType::JoinLines with correct forward/backward behavior. - Regex replace-all, indent/unindent region, kill-to-eol, kill-line, kill-region, and delete-word-prev/next mutated the buffer via the no-undo-recording raw APIs; they now record undo, grouped atomically via a shared UndoGroupGuard. - Plain-text replace-all with an empty replacement advanced the scan position one character too far, skipping adjacent/overlapping matches. Crash recovery / memory safety: - Buffer's move ctor/assignment never carried over swap_rec_, on_disk_identity_, or the visual-line-mode fields, so the crash-recovery journal silently stopped tracking a buffer whenever Editor's std::vector<Buffer> reallocated or shifted (e.g. opening/closing files). Added SwapManager::Rehome() plus Flush()-before-mutate in Editor::AddBuffer/CloseBuffer so the journal's Buffer* key and the background writer thread never reference a stale address. - UndoTree leaked its entire node graph (including all edit text) on every buffer close/reload; added ~UndoTree() to free it. - main.cc didn't restore the terminal if an exception escaped the run loop; added an RAII guard around Frontend::Shutdown(). Input handling: - Terminal frontend used getch() instead of get_wch(), silently dropping non-ASCII keyboard input despite linking wide-char ncurses. - KKeymap's C-k lookup switches on an already-lowercased key, making `case 'E'` unreachable dead code; C-k Shift-E silently aliased to C-k e. - ImGui file picker wasn't modal: keystrokes typed while it was open still reached the buffer underneath as edit commands, and Escape didn't close it. - Gated ImGuiInputHandler's unconditional fprintf/fflush diagnostics behind an IMGUI_IH_DEBUG macro, matching QtInputHandler's existing convention. Syntax highlighting: - Go/Rust/SQL highlighters weren't stateful, so multi-line /* */ comments mis-highlighted as code starting on the second line. - Python's triple-quoted-string handler didn't re-scan the remainder of a line after a string closed mid-line, missing a same-line reopen. - HighlighterEngine's state_last_contig_ field was declared but unused, forcing an O(n) scan of state_cache_ on every stateful lookup; wired it up as a real fast path and fixed InvalidateFrom() to keep it in sync. - kge's :syntax off was silently undone the next frame because apply_syntax_to_buffer() re-applied the config default unconditionally every frame; added a user-override flag mirroring the existing edit-mode-detection guard. Added regression tests for all of the above (test_undo.cc, test_kkeymap.cc, test_command_semantics.cc, test_search_replace_flow.cc, and a new test_syntax_highlighting.cc). Full suite (163 tests) passes, including under AddressSanitizer. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
