refactor(rules): split all 9 rulebooks into per-topic files

The rulebooks (Podręcznik Gry, Księga Magii, and 7 others) were single
monolithic documents, some over 1000 lines, making it hard to find or link
to one specific rule. Restructured them to match the convention already
used for lore/npcs/spells/disciplines: a themed subfolder per book with one
file per topic (talent, race, status effect, action type, etc.), and the
original book file rewritten into a hub/table-of-contents linking to them.

- Where a rulebook chapter duplicated content that already has a canonical
  home elsewhere (spell lists vs spells/, artifacts vs items/, disciplines
  vs disciplines/), replaced the duplicated text with links instead of
  copying it a second time.
- Verified all ~360 internal links across the new structure resolve, and
  fixed two real bugs surfaced by that check: unescaped parentheses in
  filenames breaking Markdown link syntax, and an off-by-one relative path
  in Rozdział VII - Religia.
