Sync parsers and game mechanics with vault changes (2026-08-18 to 08-23)

- talent-parser.ts, discipline-parser.ts, race-parser.ts: rebuilt to read
  from the vault's post-bab5a62 per-topic-file layout (rulebook monoliths
  were split into per-chapter subfolders; discipline/race writeups moved to
  their canonical disciplines/ and races/ folders). All three parsers were
  previously producing zero or broken output for their packs.
- constants.ts, actor-character.ts, actor-npc.ts, rest.ts: mana is now a
  daily pool (Poziom Mocy x3) restored via rest tiers, not a per-round
  budget; Zywotnosc is 2x(Cialo+Umysl+Dusza), not 3x; rest recovery amounts
  updated to match Odetchniecie/Krotki Odpoczynek/Dlugi Odpoczynek.
- combat.ts: removed the now-obsolete per-round mana reset hook.
- actor-npc.ts: Initiative now includes Refleks/Spostrzegawczosc skill
  bonuses (was missing entirely); Magia attribute constrained to valid
  1k10 character-creation values.
- fields.ts: added `choices` support to makeIntField for the above.
- spell-cast.ts: overcast test now uses the correct T-threshold tiers and
  triangular S = E*(E+1)/2 required-successes formula (Zasada
  Nadczarowywania Zaklec).

Not implemented (flagged as new features, out of scope for a sync fix):
mana-exhaustion/overcast-failure penalty tables, overcast bonus taper past
step 2, shield-breaking damage mechanic, elixir-weapon-coating system.
