Implement multiple game improvements

- Guardian barriers with 3x HP regen on guardian floors
- Compound mana types auto-unlock when components available
- Legs equipment slot with 5 equipment types
- Expeditious Retreat and movement enchantments for legs
- Fixed tests for current skill definitions (65/65 pass)
- New achievements for elements, attunements, and guardians
- Removed nonsensical mechanics (thorns, manaShield for player)
- Cleaned up skill test references to match current implementation

+Task: Review and find nonsensical mechanics
+
+Work Log:
+- Read worklog.md to understand previous work (Task 20 already removed some blocking/dodging)
+- Searched codebase for blocking, dodging, parry, evasion mechanics
+- Searched for player health/HP references
+- Searched for defense stats
+- Searched for thorns/reflect damage mechanics
+- Searched for healing mechanics that heal the player
+- Reviewed familiar-slice.ts and familiars.ts for thorns and manaShield
+- Reviewed skill-evolution.ts for defensive effects
+- Reviewed attunements.ts for defensive mechanics
+
+Stage Summary:
+- **Found nonsensical mechanics that should be removed**:
+
+## 1. FAMILIAR THORNS ABILITY (HIGH PRIORITY)
+**Files**: 
+- `/home/z/my-project/src/lib/game/data/familiars.ts` (lines 45-50, 150, 214, 281, 349, 405)
+- `/home/z/my-project/src/lib/game/familiar-slice.ts` (lines 36, 50, 264-265)
+- `/home/z/my-project/src/components/game/tabs/FamiliarTab.tsx` (lines 81, 196, 334)
+
+**Issue**: "Reflect X% damage taken" - The player has no health and doesn't take damage. This ability is meaningless.

+**Files**: 
+- `/home/z/my-project/src/lib/game/data/familiars.ts` (lines 74-79, 215, 282, 335, 351, 390, 406)
+- `/home/z/my-project/src/lib/game/familiar-slice.ts` (lines 38, 52, 270-271)
+
+**Issue**: "Shield absorbs X damage, costs 1 mana per X damage" - Since player doesn't take damage, this is useless.

+
+## 3. MANA NOVA UPGRADE (HIGH PRIORITY)
+**File**: `/home/z/my-project/src/lib/game/skill-evolution.ts` (line ~161)
+```
+{ id: 'mw_t4_l10_nova', name: 'Mana Nova', desc: 'When taking damage, release 5% mana as damage', milestone: 10, effect: { type: 'special', specialId: 'manaNova', specialDesc: 'Defensive burst' } }
+```
+**Issue**: "When taking damage" - Player doesn't take damage, so this never triggers.
+
+## 4. FLAVOR TEXT REFERENCE (LOW PRIORITY - COSMETIC)
+**File**: `/home/z/my-project/src/lib/game/data/familiars.ts` (line 286)
+```
+flavorText: 'It stands motionless for hours, then suddenly moves to block danger.'
+```
+**Issue**: Just flavor text mentioning "block danger" - not a mechanic, but inconsistent with game design.
+
+## 5. MANA TYPE 'barrier' (REVIEW NEEDED)
+**File**: `/home/z/my-project/src/lib/game/attunements.ts` (line 46)
+```
+| 'barrier'       // Warden - protection/defense
+```
+**Issue**: Warden attunement uses 'barrier' mana type. This may be fine if barrier mana is used for mana-related mechanics (like mana shields for mana, not HP), but the comment "protection/defense" is misleading since player has no health to protect.
+
+## Recommendation:
+1. **Remove thorns ability entirely** from familiar system - replace with a different offensive ability (e.g., "Retaliation: Deal X% of damage dealt as bonus damage")
+2. **Remove manaShield ability entirely** from familiar system - replace with mana-related bonus (e.g., "Mana Buffer: +X max mana")
+3. **Replace Mana Nova upgrade** with something that triggers on mana expenditure or combat actions instead of "taking damage"
+4. **Update flavor text** to not reference blocking
+5. **Clarify barrier mana type** purpose - if it's for mana mechanics, rename comment to reflect that

+Task ID: 1
+Agent: full-stack-developer
+Task: Implement guardian barriers and floor health regen
+
+Work Log:
+- **Updated getFloorHPRegen() function** in store.ts:
+  - Changed guardian floors from 0 regen to 3% per hour (3x the usual)
+  - Non-guardian floors now have fixed 1% per hour regen
+  - This makes floors progressively harder during combat
+- **Updated combat tick logic** in store.ts:
+  - Removed the condition that excluded guardian floors from HP regen
+  - All floors now regenerate HP during combat (climbing action)
+  - Guardian floors regen 3% per hour, non-guardian floors regen 1% per hour
+- **Fixed initial barrier state** in makeInitial():
+  - Changed from hardcoded 0 to dynamic getFloorBarrier(startFloor)
+  - Ensures barriers are properly initialized if player starts on a guardian floor
+- **Updated SpireTab UI** with improved barrier and HP regen display:
+  - Added Shield icon for barrier indicator
+  - Added "(no regen)" text to clarify barriers don't regenerate
+  - Improved barrier bar visual with gradient (gray tones)
+  - Added HP regen indicator during combat: shows "+X/hr" with pulsing Heart icon
+  - Added getFloorHPRegen import from store
+  - Added HOURS_PER_TICK, Heart, and Shield imports
+
+Stage Summary:
+- Guardian barriers are now fully functional as a one-time shield (no regen)
+- All floors regenerate HP during combat, making battles more challenging
+- Guardian floors regen 3% per hour, non-guardian floors regen 1% per hour
+- UI clearly shows barrier status and HP regen rate during combat
+- All lint checks pass

+Task ID: 8
+Agent: full-stack-developer
+Task: Implement compound mana types
+
+Work Log:
+- **Added composite element utility functions to constants.ts**:
+  - `canUnlockCompositeElement()`: Checks if all recipe components are unlocked
+  - `getUnlockableCompositeElements()`: Returns list of composite elements that can be unlocked
+  - `getCompositeConversionRate()`: Calculates rate as half of slowest component rate
+  - `getBaseElementConversionRates()`: Gets rates from attunements for calculation
+
+- **Updated store.ts tick function**:
+  - Added imports for new composite element functions
+  - Added composite element unlocking logic after attunement mana conversion
+  - When both components of a composite element are unlocked, the composite element unlocks
+  - Log message shows unlock with recipe (e.g., "🔮 Metal mana unlocked! (Fire + Earth)")
+  - Added composite element conversion logic:
+    - Calculates conversion rate as half of slowest component
+    - Converts from component elements to composite element
+    - Checks capacity and available mana before conversion
+    - Handles composite elements: metal (fire+earth), blood (life+water), wood (life+earth), sand (earth+water)
+    - Handles exotic elements: crystal (sand+mental), stellar (fire+light), void (dark+death)
+
+- **Updated ManaDisplay.tsx UI**:
+  - Added `baseConversionRates` prop for showing composite conversion rates
+  - Sorted elements by category (base/utility first, then composite/exotic)
+  - Added "Compound Elements" section with Sparkles icon
+  - Shows recipe for each composite element (e.g., "🔥+⛰️" for Metal)
+  - Shows conversion rate (e.g., "+1.00/hr")
+  - Visual distinction with colored border accents
+
+- **Updated page.tsx**:
+  - Added import for `getAttunementConversionRate` and `ATTUNEMENTS_DEF`
+  - Computed `baseConversionRates` from active attunements
+  - Passed `baseConversionRates` to ManaDisplay component
+
+Stage Summary:
+- Composite elements (metal, blood, wood, sand) automatically unlock when both components are unlocked
+- Exotic elements (crystal, stellar, void) also supported with triple-component recipes
+- Conversion rate is half of slowest component rate as specified
+- UI shows compound elements in separate section with recipes and rates
+- All lint checks pass
