- Fall back to the current thread when the delete worker fails to load

-## Highlights
-### Added
-- **In-App Changelog**
-  - View release notes without leaving the app, from the tray menu ("View Changelog") or the "What's New" button on update notifications.
-  - Shows notes for the latest published release even when it's newer than your installed build, and falls back to the notes bundled with your install if the download fails.
-  - Older versions fold automatically, your installed version is badged, and newer ones are tagged "New"; navigate with `J`/`K` or the arrow keys, `Enter` to expand/collapse, `R` to refresh, and `Esc` to close.

-### Changed
-- **Faster Subtitle Tokenization**
-  - Subtitle lines are parsed and looked up roughly twice as efficiently, with results cached across lines so repeated words and grammar no longer re-query the dictionary.
-  - Enabling a character dictionary no longer slows subtitle scanning as much, since name lookups now only check positions where a known name can actually start.
-  - Fixed related accuracy issues along the way: readings that could go missing on certain word endings, subtitle text that stayed unannotated after mining a card, character names that could drop out of disambiguation rules, and halfwidth-katakana character names that weren't recognized or read correctly.
-
-### Fixed
-- **Large Character Dictionary Generation**
-  - Big character dictionaries (long-running series like One Piece) no longer fail to install with a timeout error; the import time budget now scales with dictionary size instead of using a fixed 7-second limit.
-  - The "Generating character dictionary" notification now shows real progress (character/page counts, image download progress with an ETA, name-processing progress) and an elapsed-time clock, so a long-running import no longer looks frozen.
-- **Stats Deletion Responsiveness**
-  - Deleting sessions, episodes, or library entries on the stats page no longer freezes the page or an active video player; deletes are now batched into a single transaction.
-- **Subtitle Sidebar Clutter from Styled Subtitles**
-  - Heavily typeset subtitles (karaoke openings/endings, stylized signs) no longer flood the subtitle sidebar with garbled vector-drawing text or duplicate "shadow" copies of the same line.
-  - Subtitle text is now decoded consistently in one place, matching what mpv actually renders on screen, so it can no longer diverge or get cached inconsistently.
-- **X11/XWayland Playback and Overlay Fixes**
-  - Fixed a crash on the first fullscreen toggle when using an mpv `gpu-next` shader (e.g. ArtCNN) in X11/XWayland mode; SubMiner no longer forces mpv onto its older OpenGL renderer.
-  - Fixed the overlay appearing oversized and offset from the video under fractional or mixed-monitor display scaling in X11/XWayland mode.
