The bab5a62 vault commit split 9 rulebook monoliths into hub/ToC pages plus
per-topic-file subfolders (rules/NN. <Book>/<Chapter>/<Topic>.md). The
existing chapter-slicing parser (parseJournalBook) relied on finding a
duplicate TOC-vs-body heading pair per chapter; after the split each hub
heading only occurs once (in the ToC), so it was silently treating the
ToC's link-list body as if it were real chapter content.
Added parseSplitBookFolder (journal-parser.ts): walks a book's split
subfolder directly, one JournalDoc per Rozdzial/Aneks subfolder-or-file,
one JournalPage per topic file (or a single page for a standalone chapter
file). The hub's own Wstep intro paragraph is unaffected by the split (it's
still real prose, not a link) and continues to come from the existing
prefaceTitle preface-extraction logic.
Wired into build-journal-packs.ts for the 6 affected packs: core-rules-lore,
bestiary-lore, magic-book-lore, abyss, blood-magic-history, economy.
crimson-cult's rules source was never split into a subfolder, so it's left
on the old code path unchanged.
Also fixed a pre-existing derivePageTitle bug (page titles kept a leading
markdown heading marker, e.g. "## Wstep" instead of "Wstep") to match the
already-correct behavior in topical-parser.ts.
