Add View Characters + recast-all/selected once a book is already cast (v1.13.1)

"Cast Characters" always blindly regenerated the whole cast from
scratch, even for a book already fully cast - no way to just look at
what's there or touch up a handful of characters without redoing
everyone. Once clGetAllByTagOrBook finds existing characters for this
book, the button becomes a split control: View Characters (jump to the
Library overview) plus a dropdown for Recast all or Recast selected...
(checkbox picker that re-scans the book but only saves updates for the
characters checked).

+## [1.13.1] — 2026-07-06
+
+### Added
+- **"View Characters" + recast options once a book's already cast** — Read Aloud's Casting view no longer offers a single blind "Cast Characters" button once this book already has saved characters. It becomes a split button: **View Characters** jumps straight to the Library's character overview, and the dropdown caret offers **Recast all** (previous behavior) or **Recast selected…**, which opens a checkbox picker of the existing cast and only refreshes the ones you check — everyone else's saved sheet is left untouched. (Extraction still re-scans the whole book either way, since any page could mention any character; "selected" just controls what gets saved afterward, not what gets read.)
