unsave_from_preview only refreshed the library grid when on the
library tab. Now also refreshes the bookmarks grid when on the
bookmarks tab so the saved dot clears immediately.
New setting "Remove bookmark when saved to library" (off by default).
When enabled, _maybe_unbookmark runs directly in each save callback
after save_post_file succeeds -- handles DB removal, grid dot, preview
state, popout sync, and bookmarks tab refresh. Wired into all 4 save
paths: save_to_library, bulk_save, save_as, batch_download_to.
behavior change: opt-in setting, off by default
New setting "Remove bookmark when saved to library" (off by default).
When enabled, saving a post to the library automatically removes its
bookmark. Handles both single saves (on_bookmark_done) and bulk saves
(on_batch_done). UI toggle in Settings > General.

CI installs httpx + Pillow + pytest but not PySide6. The Phase C
tests import pure functions from controller modules, which had
top-level PySide6 imports (QTimer, QPixmap, QApplication, QMessageBox).
Move these to lazy imports inside the methods that need them so the
module-level pure functions remain importable without Qt.
Move 26 bookmark/save/library/batch/blacklist methods and _batch_dest
state into gui/post_actions.py. Rewire 8 signal connections and update
popout_controller signal targets.
Extract is_batch_message and is_in_library as pure functions for
Phase 2 tests. main_window.py: 1935 -> 1400 lines.
behavior change: none
