fix(bundle): mirror source fixes in embedded userscript

Mirror the three source-level fixes in the embedded copies inside
torn-attribute-tracker.user.js:

1. _wireHeaderDrag: add the .tat-header closest() guard so the bundle
   no longer steals focus from inputs/selects.
2. findAnchorElement: replace the narrow 'button[name="train"]' query
   with the priority-ordered candidate list and the gym-panel last-
   ditch fallback.
3. Inline anchor-error UX: add the anchorError state, include it in
   the snapshot, surface it via applyMode, render the note with the
   .tat-anchor-err class, and add the corresponding CSS rule.
