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

Work Log:
- **Fixed Quick Learner tier-up reset issue**: Modified `tierUpSkill()` to NOT copy upgrades from old tier to new tier. Each tier now starts with empty upgrades, allowing players to choose new tier-specific upgrades at level 5 and 10.
- **Implemented Parallel Mind milestone upgrade**: Added parallel study support to the tick function and created actions for starting/canceling parallel study. Players can now study two things at once at 50% speed each.
- **Fixed meditation multiplier display**: Removed meditation multiplier from "Active Spell" card in Spire tab - it now only appears in the Mana Stats section.
- **Added parallel study UI**: 
  - Added parallel study progress card in Spire tab
  - Added ⚡ button in Skills tab for selecting parallel study target
  - Shows "50% speed (Parallel Study)" indicator
- **Verified combat uses active spells**: Confirmed that combat properly uses the active spell from `state.activeSpell`, calculates damage based on spell definition, applies elemental bonuses, and handles spell effects like lifesteal.
- **Added parallelStudyTarget to state persistence**: Updated the persist partialize function to include parallelStudyTarget.
- **Fixed TypeScript errors**: Updated `computeElementMax` call in makeInitial to include required parameters.

Stage Summary:
- Quick Learner and other skills no longer lose progress when tiering up - players choose new upgrades for each tier
- Parallel Mind upgrade is now functional - allows studying two skills/spells simultaneously

Agent: Main
  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

- **Verified DPS/casts per hour display**:
  - DPS = damagePerCast × castsPerSecond
  - Casts per second = castSpeed × HOURS_PER_TICK / (TICK_MS / 1000)
  - Cast speed affected by spell base speed and attack speed multipliers
  - UI shows cast progress bar and DPS when climbing
- **Created AGENTS.md**:
  - Comprehensive project architecture documentation

- Updated imports to use extracted components
- Cleaned up unused imports (`MAX_DAY`, `INCURSION_START_DAY`, `MANA_PER_ELEMENT`)
- Created `tabs/index.ts` for cleaner tab component exports
- Updated `game/index.ts` to export all new components

**Results:**
- All lint checks pass
- Functionality preserved - all features working as before
- Better code organization with reusable components
- Easier maintenance with separated concerns

## Task ID: 1 - Code Extraction
### Work Task
Extract computed stats and utility functions from `/home/z/my-project/src/lib/game/store.ts` into a new file `/home/z/my-project/src/lib/game/computed-stats.ts`. The store.ts was ~2100 lines with functions that could be better organized in a separate module.

### Work Summary
**Created New File:** `computed-stats.ts`

**Functions Extracted:**
1. `DEFAULT_EFFECTS` constant - Default empty effects object for computed effects
2. `fmt` and `fmtDec` - Number formatting utilities (K, M, B suffixes)
3. `getFloorMaxHP` - Floor HP calculation with guardian and scaling logic
4. `getFloorElement` - Floor element determination from cycle
5. `getActiveEquipmentSpells` - Helper to get all spells from equipped caster weapons
6. `getEffectiveSkillLevel` - Helper for tiered skill level calculation
7. `computeMaxMana` - Maximum mana calculation with effects
8. `computeElementMax` - Elemental mana capacity calculation
9. `computeRegen` - Mana regeneration rate calculation
10. `computeEffectiveRegen` - Regen with dynamic special effects
11. `computeClickMana` - Click mana gain calculation
12. `getElementalBonus` - Elemental damage bonus helper
13. `calcDamage` - Damage calculation with skills, pacts, and crits
14. `calcInsight` - End-of-loop insight calculation
15. `getMeditationBonus` - Meditation multiplier calculation
16. `getIncursionStrength` - Time-based incursion penalty
17. `canAffordSpellCost` - Check if player can afford spell
18. `deductSpellCost` - Deduct spell cost from mana pool

**Files Updated:**
- `store.ts`: 
  - Added imports from computed-stats.ts
  - Removed duplicate function definitions
  - Kept local `getElementalBonus` helper (used only in store)
  - Re-exports `fmt` and `fmtDec` for backward compatibility
- `formatting.ts`:
  - Added re-exports of `fmt` and `fmtDec` from computed-stats.ts

**Results:**
- All lint checks pass
- No functionality changed - pure refactoring
- Better code organization with computed stats in dedicated module
- Easier to test and maintain individual functions
- Backward compatible - existing imports still work

  - Added re-exports for computed stats functions (`getFloorElement`, `computeMaxMana`, `computeRegen`, `computeClickMana`, `calcDamage`, `getMeditationBonus`, `getIncursionStrength`, `canAffordSpellCost`, `getFloorMaxHP`)
  - Added missing imports for `EQUIPMENT_TYPES` and `EquipmentInstance`

**Pattern Followed:**
- Followed existing slice patterns from `familiar-slice.ts` and `crafting-slice.ts`
