feat(release): v0.5.0 - Dioxus 0.7.3 GUI Framework Migration

BREAKING CHANGE: Complete GUI framework migration from iced 0.14.0 to Dioxus 0.7.3.

## GUI Framework Migration
- Replaced iced 0.14.0 with Dioxus 0.7.3 (Blitz native renderer for desktop)
- Signal-based reactivity replaces iced Message/Update pattern
- 18 RSX components replace iced widget implementations
- CSS custom properties + Tailwind replace iced ColorPalette structs
- EventBus bridge via ChannelEventHandler + use_coroutine()
- Feature flags: desktop (default), server (Axum SSR), web (WASM)

## Core Bug Fixes
- Fixed drop() on async future in connection.rs silently discarding Event::Connected
- Fixed premature ConnectionState::Registered before server 001 RPL_WELCOME
- Fixed PONG handler not sending PONG through writer channel
- Moved 001 RPL_WELCOME handling into reader task for proper async emission

## Runtime Fixes
- Explicit tokio Runtime::new() + rt.enter() for Dioxus desktop compatibility
- rustls::crypto::ring::default_provider().install_default() for rustls 0.23+
- spawn_forever() for network operations surviving component unmount
- OnceLock<Arc<IrcClient>> global pattern for Copy-compatible IrcActions

## New Architecture
- 18 RSX components in crates/rustirc-gui/src/components/
- bridge.rs: EventBus to Dioxus channel bridge
- providers.rs: Context providers for signals
- hooks/: use_irc.rs, use_irc_actions.rs, use_theme.rs
- state.rs: Dioxus-compatible AppState with Signal wrapping
- assets/main.css, assets/themes/base.css, assets/tailwind.css
- Dioxus.toml project configuration

## Removed
- All iced widget implementations (crates/rustirc-gui/src/widgets/)
- iced ColorPalette theme system
- vendor/iced_glyphon/ security patch
- --material-demo flag and Material Design 3 iced components

## Other
- All crate versions bumped to 0.5.0
- MSRV updated from 1.75.0 to 1.80.0
- 254 tests passing (zero regressions), zero clippy warnings
- 22 CSS themes via [data-theme="..."] selectors
- Updated .gitignore for Dioxus build artifacts

+## [0.5.0] - 2026-03-07 (Dioxus 0.7.3 + Axum GUI Migration)
+
+### Summary
+Major release replacing the iced 0.14.0 GUI framework with Dioxus 0.7.3 + Axum. The GUI is now built with reactive RSX components, Signal-based state management, Tailwind CSS styling, and CSS custom property themes. Adds web target support via Axum fullstack. All non-GUI functionality (core, protocol, TUI, scripting, plugins) unchanged.
+
+### Added
+
+#### Dioxus GUI Framework
+- **Dioxus 0.7.3**: Reactive RSX component architecture replacing iced 0.14.0
+- **Axum 0.8**: Fullstack web target support via `#[server]` functions
+- **Signal<AppState>**: Reactive state management with automatic re-rendering
+- **EventBus Bridge**: `use_coroutine()` bridges core EventBus to Dioxus signals
+- **IrcActions**: Copy-type action dispatcher for connect, send, join, leave operations
+- **18 RSX Components**: Layout, TabBar, ServerTree, UserList, MessageView, InputArea, StatusBar, MenuBar, SearchBar, ContextMenu, UrlPreview, DccTransfer, DccChat, ScriptConsole, PluginManager, and 3 dialog components
+- **CSS Theme System**: 22 themes as CSS custom properties with `[data-theme="..."]` selectors
+- **Tailwind CSS**: Zero-config utility-first CSS in RSX class attributes
+- **IRC Color CSS**: mIRC color codes 0-15 as `.irc-color-N` CSS classes
+- **Feature Flags**: `desktop`, `server`, `web` features for target selection
+- **Dioxus.toml**: Configuration for dx CLI (hot-patching, asset directory)
+
+#### New Tests
+- 14 state management unit tests (CRUD operations, message limits, user management)
+- 5 formatting tests (IRC color parsing, CSS style generation)
+- 6 theme tests (roundtrip, case-insensitive parsing, display names)
+
+### Changed
+- **GUI Framework**: iced 0.14.0 -> Dioxus 0.7.3 (complete rewrite)
+- **Styling**: Rust `ColorPalette` structs -> CSS custom properties + Tailwind
+- **IRC Colors**: `iced::Color` values -> CSS hex strings
+- **Theme System**: Rust enum -> CSS `[data-theme]` attribute selectors
+- **MSRV**: 1.75.0 -> 1.80.0 (Dioxus requirement)
+- **Version**: 0.4.2 -> 0.5.0
+- **CI MSRV Job**: Updated toolchain from 1.75.0 to 1.80.0
+- **Formatting Module**: Output changed from iced elements to CSS-styled HTML spans
+
+### Removed
+- **iced 0.14.0**: Entire iced dependency and all widget implementations
+- **vendor/iced_glyphon/**: Security patch directory no longer needed
+- **Material Design 3 Widgets**: iced-specific MD3 components (typography, buttons, cards, etc.)
+- **--material-demo flag**: iced component showcase removed
+- **SerializableColor**: Wrapper type replaced by CSS hex strings
+- **iced Widget Files**: `widgets/`, `themes/`, `theme.rs`, `event_handler.rs`, `menus.rs`, `dialogs.rs`, `material_demo.rs`, `accessibility.rs`, `notifications.rs`, `performance.rs`, `platform.rs`, `search.rs`, `testing.rs`, `simple_app.rs`
+- **iced Patch**: `[patch.crates-io]` section for iced_glyphon
+
+### Fixed
+
+#### Core IRC Engine (`crates/rustirc-core/src/connection.rs`)
+- **`drop()` on async future**: Fixed `drop()` call that silently discarded `Event::Connected` emission, preventing connection state from propagating
+- **Premature `ConnectionState::Registered`**: Fixed state being set to `Registered` before server's 001 RPL_WELCOME response; moved to reader task for proper async event emission
+- **PONG handler**: Fixed handler that only emitted events about PONG but never actually sent PONG through the writer channel
+
+#### Runtime Compatibility
+- **Tokio runtime**: Added explicit `Runtime::new()` + `rt.enter()` for Dioxus desktop compatibility
+- **rustls 0.23+ TLS**: Added explicit `rustls::crypto::ring::default_provider().install_default()` call
+- **`spawn_forever()`**: Used instead of `spawn()` for network operations to survive component unmount
+- **`OnceLock<Arc<IrcClient>>`**: Global pattern keeps `IrcActions` as `Copy` (required for RSX closures in `for` loops)
+- **CSS loading**: `include_str!()` + `document::Style` instead of `asset!()` macro (only works with dx CLI)
+
+### Technical Details
+- ~24K lines of iced GUI code replaced by ~6K lines of Dioxus RSX
+- All 254 workspace tests passing (zero regressions)
+- Zero clippy warnings
+- Auto-join channels via `pending_auto_joins` HashMap, executed on `Event::Connected`
+

 ### GUI Debugging & Issue Resolution
 
 When addressing GUI issues in RustIRC:
 
 1. **IRC Protocol Verification**: Always check field names against protocol definitions (e.g., WHOIS uses `targets` not `target/nickmasks`)
-2. **Iced 0.14.0 Styling**: Use proper border syntax with `0.0.into()` for radius, container styling for pane dividers
+2. **Dioxus RSX Styling**: Use Tailwind CSS classes in RSX `class` attributes; CSS custom properties for themes
 3. **Case-Sensitive Filtering**: Handle both "System" and "system" message senders in filtering logic
-4. **State Synchronization**: Use getter methods like `get_filter_state()` to sync UI checkmarks with actual filter states

-### Material Design 3 Implementation Patterns (August 26, 2025)
+### Historical Note
 
-**SerializableColor Architecture for Config Persistence**:
-
-1. **Wrapper Type Implementation**:
-
-   - Create `SerializableColor` struct wrapping `[f32; 4]` for RGBA values
-   - Implement `serde::Serialize` and `serde::Deserialize` traits
-   - Add bidirectional conversions with `From<iced::Color>` and `Into<iced::Color>`
-   - Include `Copy` trait for performance optimization
-
-2. **API Compatibility Methods**:
-
-   - Implement `scale_alpha()` method for transparency adjustments
-   - Provide color manipulation methods matching iced::Color API
-   - Enable `.into()` conversions throughout codebase
-
-3. **Proven Error Resolution Patterns**:
-
-   - **Clone-before-move**: Resolve lifetime issues with `.clone()` before moving
-   - **Into conversions**: Use `.into()` for automatic color type conversions
-   - **Module-by-module**: Fix typography/input/chip first (0 errors), then apply patterns
-
-4. **Achievement Metrics**:
-   - Error reduction: 424 → 0 (100% reduction achieved)
-   - All modules: ZERO errors across all components
-   - Final status: 100% functional Material Design 3 implementation
-
-### Material Design 3 100% Completion Patterns (August 26, 2025 09:42 PM EDT)
-
-**Complete Error Elimination Strategy**:
-
-1. **Multi-Stage Sub-Agent Approach**:
-   - Sub-agent 1: Reduced errors from 424 → 40 (91% reduction)
-   - Sub-agent 2: Eliminated remaining 40 → 0 (100% complete)
-   - Key: Systematic application of proven patterns
-
-2. **Lifetime Management Resolution**:
-   - E0373: Extract values before move closures
-   - E0515: Clone instead of borrowing for return values
-   - E0382: Clone-before-move pattern for ownership
-   - E0310: Proper 'static lifetime annotations
-
-3. **Production Code Quality**:
-   - ZERO compilation errors achieved
-   - ZERO clippy warnings (73 warnings eliminated)
-   - 6 comprehensive doctests added and passing
-   - All public APIs documented with examples
-
-4. **Component Completeness**:
-   - All Material Design 3 components 100% functional
-   - SerializableColor with full config persistence
-   - MaterialText/MaterialButton .build() APIs complete
-   - Responsive layouts with proper enum traits
+The Material Design 3 / iced implementation patterns from v0.3.x-v0.4.x have been superseded by the Dioxus 0.7.3 migration in v0.5.0. The iced widget system, SerializableColor wrapper, and iced-specific lifetime patterns are no longer applicable. See the "Dioxus GUI Patterns" section above for current architecture guidance.
