Task: Fix multiple issues: Quick Learner tier-up reset, Parallel Mind upgrade, meditation display location, parallel study UI, combat spell usage verification

  - Added parallel study progress card in Spire tab
  - Added ⚡ button in Skills tab for selecting parallel study target
  - Shows "50% speed (Parallel Study)" indicator

Stage Summary:
- Quick Learner and other skills no longer lose progress when tiering up - players choose new upgrades for each tier

  Task: Implement cast speed system for combat

  Work Log:
  - Added `castSpeed` property to `SpellDef` type in types.ts (default 1 cast/hour)
  - Added cast speeds to all spells in SPELLS_DEF:
    - Tier 0 (basic): 2.5-3 casts/hr (fast, cheap)
    - Tier 1 (elemental): 1.5-3 casts/hr (varies by spell nature)
    - Tier 2 (advanced): 0.8-1.8 casts/hr (slower, more powerful)
    - Tier 3 (master): 0.5-0.75 casts/hr (slow but devastating)
    - Tier 4 (legendary): 0.4-0.5 casts/hr (very slow, extremely powerful)
  - Added `castProgress` to GameState (tracks progress to next cast, 0-1)
  - Updated combat tick logic:
    - Accumulates cast progress based on spell cast speed and attack speed bonuses
    - When progress >= 1, triggers a spell cast (deducts mana, applies damage)
    - Handles multiple casts per tick if cast speed is high
    - Resets progress on floor change
  - Attack speed affected by:
    - Quick Cast skill: +5% per level
    - Attack Speed upgrade multipliers from skill milestones
  - Updated UI:
    - Active Spell card now shows cast speed (casts/hr)
    - Added cast progress bar when climbing
    - DPS calculation now uses actual cast speed formula

  Stage Summary:
  - Combat now properly uses spell cast speed instead of arbitrary damage multiplier
  - Each spell has unique cast speed (faster spells = more DPS but lower damage per cast)
  - Attack speed upgrades (Quick Cast, Quick Strikes) properly speed up casting
  - Players can see cast progress and DPS in real-time
