## Summary - **What is the goal of this PR?** Add chapter selection support to the XTC reader activity, including parsing chapter metadata from XTC files. - **What changes are included?** Implemented XTC chapter parsing and exposure in the XTC library, added a chapter selection activity for XTC, integrated it into XtcReaderActivity, and normalized chapter page indices by shifting them to 0-based. ## Additional Context - The reader uses 0-based page indexing (first page = 0), but the XTC chapter table appears to be 1-based (first page = 1), so chapter start/end pages are shifted down by 1 during parsing.
