+- Added `status`, `validate`, `edit`, `history`, and `stats` CLI commands.
+- Added `run --dry-run` and `run --no-actions` for safer timer verification.
+- Added TUI pause/resume support and a fullscreen running timer view with large ASCII time-left display.
+- Added history recording for completed sessions and aggregate sleep/timer statistics.
+- Added red highlighting for dangerous post-timer actions and common destructive custom commands.
+
+### Changed
+
+- TUI settings now hide dependent options when their parent action is disabled.
+- Release assets are published as a raw Linux binary plus `.sha256` instead of a tar archive.
