feat: Complete Leptos v0.8 compatibility migration

- Migrate all 46 components to Leptos v0.8 attribute system
- Fix Signal trait bound issues by wrapping signal access in move || closures
- Update attribute syntax: class=computed_class -> class=move || computed_class.get()
- Fix date-picker component signal handling for Calendar component
- All components now compile successfully with Leptos v0.8
- Create automated migration script for future reference

Migration Summary:
- Button, Input, Label: Manual migration completed
- 42 additional components: Automated migration via script
- Date-picker: Special handling for Signal<Vec<CalendarDate>> requirements
- All components tested and verified to compile

Breaking Changes:
- Attribute syntax changes require updating user code
- Signal access patterns updated for v0.8 compatibility

Ready for v0.6.0 release with full Leptos v0.8 support

+# 🚀 Leptos v0.8 Migration Plan
+
+**Comprehensive plan to migrate all leptos-shadcn-ui components to Leptos v0.8's new attribute system**
+
+## 🎯 **Problem Statement**
+
+The current leptos-shadcn-ui v0.5.0 components are **NOT COMPATIBLE** with Leptos v0.8 due to:
+
+1. **Signal Trait Bound Issues**
+   - `Signal<String>: IntoClass` not satisfied
+   - `Signal<bool>: IntoAttributeValue` not satisfied  
+   - `RwSignal<String>: IntoProperty` not satisfied
+
+2. **Missing Attribute Implementations**
+   - `on:click` method trait bounds not satisfied
+   - `id`, `type`, `disabled` method trait bounds not satisfied
+   - HTML element attribute methods not working
+
+3. **Affected Components**
+   - `leptos-shadcn-input-otp` - 2 compilation errors
+   - `leptos-shadcn-command` - 2 compilation errors
+   - `leptos-shadcn-input` - 6 compilation errors
+   - `leptos-shadcn-button` - 6 compilation errors
+   - **All 46 components** need migration
+
+## 🔧 **Migration Strategy**
+
+### **Phase 1: Attribute System Migration**
+Update all components to use Leptos v0.8's new attribute system:
+
+#### **Old v0.7 Syntax → New v0.8 Syntax**
+```rust
+// OLD (v0.7) - ❌ NOT WORKING
+<button
+    class=computed_class
+    id=id.get().unwrap_or_default()
+    style=move || style.get().to_string()
+    disabled=disabled
+    on:click=handle_click
+>
+
+// NEW (v0.8) - ✅ WORKING
+<button
+    class=move || computed_class.get()
+    id=move || id.get().unwrap_or_default()
+    style=move || style.get().to_string()
+    disabled=move || disabled.get()
+    on:click=handle_click
+>
+```
+
+#### **Key Changes Required:**
+1. **Signal Access**: Wrap all signal access in `move ||` closures
+2. **Class Attributes**: `class=computed_class` → `class=move || computed_class.get()`
+3. **ID Attributes**: `id=id.get()` → `id=move || id.get()`
+4. **Style Attributes**: Keep `style=move || style.get().to_string()`
+5. **Disabled Attributes**: `disabled=disabled` → `disabled=move || disabled.get()`
+6. **Event Handlers**: Keep `on:click=handle_click` (no changes needed)
+
+### **Phase 2: Signal Handling Updates**
+Update signal handling to work with new trait bounds:
+
+#### **Signal to Attribute Conversion**
+```rust
+// OLD - Direct signal usage
+class=computed_class
+disabled=disabled
+
+// NEW - Proper signal handling
+class:move || computed_class.get()
+disabled:move || disabled.get()
+```
+
+### **Phase 3: Component-by-Component Migration**
+Systematically migrate all 46 components:
+
+#### **Priority Order:**
+1. **Core Form Components** (Button, Input, Label, Checkbox)
+2. **Layout Components** (Card, Separator, Tabs, Accordion)
+3. **Overlay Components** (Dialog, Popover, Tooltip)
+4. **Navigation Components** (Breadcrumb, Navigation Menu)
+5. **Feedback Components** (Alert, Badge, Toast)
+6. **Advanced Components** (Table, Calendar, Form)
+
+## 📋 **Detailed Migration Steps**
+
+### **Step 1: Update Button Component**
+**File**: `packages/leptos/button/src/default.rs`
+
+**Changes Required:**
+```rust
+// BEFORE (v0.7)
+<button
+    class=computed_class
+    id=id.get().unwrap_or_default()
+    style=move || style.get().to_string()
+    disabled=disabled
+    on:click=handle_click
+>
+
+// AFTER (v0.8)
+<button
+    class:move || computed_class.get()
+    id:move || id.get().unwrap_or_default()
+    style:move || style.get().to_string()
+    disabled:move || disabled.get()
+    on:click=handle_click
+>
+```
+
+### **Step 2: Update Input Component**
+**File**: `packages/leptos/input/src/default.rs`
+
+**Changes Required:**
+```rust
+// BEFORE (v0.7)
+<input
+    r#type=input_type.get().unwrap_or_else(|| "text".to_string())
+    value=value.get().unwrap_or_default()
+    placeholder=placeholder.get().unwrap_or_default()
+    disabled=move || disabled.get()
+    class=move || computed_class.get()
+    id=id.get().unwrap_or_default()
+    style=move || style.get().to_string()
+    on:input=handle_input
+/>
+
+// AFTER (v0.8)
+<input
+    type:move || input_type.get().unwrap_or_else(|| "text".to_string())
+    value:move || value.get().unwrap_or_default()
+    placeholder:move || placeholder.get().unwrap_or_default()
+    disabled:move || disabled.get()
+    class:move || computed_class.get()
+    id:move || id.get().unwrap_or_default()
+    style:move || style.get().to_string()
+    on:input=handle_input
+/>
+```
+
+### **Step 3: Update All Other Components**

+## 🚨 **Risk Mitigation**
+
+### **Potential Risks**
+1. **Breaking Changes**: Users need to update their code
+2. **Complex Migration**: Some components may be complex
+3. **Testing Overhead**: Extensive testing required
+4. **Timeline Pressure**: Migration may take longer than expected
+
+### **Mitigation Strategies**
+1. **Clear Documentation**: Provide migration guide
+2. **Incremental Approach**: Migrate components in batches
+3. **Comprehensive Testing**: Test thoroughly at each step
+4. **Flexible Timeline**: Allow for additional time if needed
+
+## 📅 **Timeline**
+
+### **Total Duration**: 4 weeks
+### **Start Date**: Today
+### **Target Completion**: 4 weeks from start
+### **Release Date**: v0.6.0 after completion
+
+---
+
+**🎯 Goal: Make leptos-shadcn-ui fully compatible with Leptos v0.8 while maintaining all existing functionality and performance.**
