fix: bugs #238,#240,#244,#246 + docs #248 update

- #238: Fix spire tab inconsistent state (Max Floor 1 but Floors Cleared 0) by not inflating maxFloorReached on enterSpireMode and preserving it on exitSpireMode
- #240: Fix guardian armor display stray text by extracting stat formatters in SpireSummaryTab
- #244: Improve discipline auto-pause UX with log messages and visual feedback on DisciplineCard
- #246: Fix raw mana exceeding max cap by recomputing maxMana after discipline XP gains
- #248: Update AGENTS.md (remove gitea_get_project_boards, add gitea_start_session, 22 mana types, 8 stores, updated guardian tiers)
- #248: Update README.md (remove Prisma/SQLite refs, update mana types/guardian tiers/discipline counts)
- #248: Update GAME_BRIEFING.md (8 stores, 22 mana types, 64 disciplines, 8-tier guardians, correct code architecture)
