feat: major feature additions and improvements (#135)

## Summary This PR includes major feature additions, bug fixes, comprehensive testing improvements, and responsive design enhancements! ## New Features ✨ ### Plugin & MCP Management (#133, #134) - **Plugin Management Panel**: Install, uninstall, enable/disable, and update plugins - **MCP Server Management Panel**: Add/remove MCP servers, view detailed configuration - **Marketplace Management**: Add/remove plugin marketplaces from GitHub - Backend commands for full CLI integration (`list_plugins`, `install_plugin`, `add_mcp_server`, etc.) - Beautiful UI with proper loading states, error handling, and theme support ### Visual Todo List Panel (#132) - Real-time todo list display when Hikari uses the `TodoWrite` tool - Shows pending/in-progress/completed status with visual indicators - Progress bar and completion count - Automatically clears on disconnect - Theme-aware styling ### Clear Session History Button (#130) - "Clear All Sessions" button in Session History panel - Confirmation dialog with session count - Keyboard support and accessibility features - Gives users control over disk usage ### CLI Version Display (#131) - Displays Claude CLI version in status bar - Auto-polls every 30 seconds for updates - Useful for debugging and feature compatibility ## Bug Fixes 🐛 ### Stats Panel Scrolling (#136) - **Fixed stats panel overflow**: Added scrollable container with `max-height` constraint - Stats panel now scrolls when content (Tools Used, Historical Costs, Budget sections) gets too long - Prevents content from overflowing off screen ### Agent Monitor Fixes (#122) - **Fixed agents stuck in "running" state**: Added `SubagentStop` hook parsing - **Fixed agents persisting after disconnect**: Call `clearConversation()` on disconnect - **Fixed "Kill All" button**: Now properly marks all agents as errored - **Fixed badge persisting after tab close**: Cleanup agents when conversation is deleted - Comprehensive tests for agent lifecycle management ### Discord RPC Cleanup (#129) - Removed file-based logging for Discord RPC - Replaced with proper `tracing` framework usage - Reduces disk usage and eliminates maintenance burden ### Close Modal Bug Fix (#128) - Fixed close confirmation modal not triggering after Discord RPC refactor - Removed frontend calls to deleted `log_discord_rpc` command - Modal now works correctly after all operations ### Responsive Design Fixes (#118) - Fixed top navigation icons getting cut off at small screen widths - Fixed Connect button disappearing on narrow screens - Fixed bottom status info (clock, CLI version) getting cut off - Added flex-wrap and mobile-optimised layouts - Icons-only mode on screens < 640px - Vertical stacking on screens < 768px ## Testing Improvements 🧪 ### Comprehensive Test Coverage (#114) - **417 backend tests** (up from 408) - **387 frontend tests** (up from 363) - **61%+ backend code coverage** - Added E2E integration tests for cross-platform notification commands - New test files: `agents.test.ts`, comprehensive CLI parsing tests - Tests for `debug_logger.rs`, `bridge_manager.rs`, `notifications.rs` - Console mocking for cleaner test output - Fixed flaky frontend tests ### Testing Documentation - Updated CLAUDE.md with comprehensive testing guidelines - Documented mocking approaches (console mocking, E2E command structure testing) - Added step-by-step guide for adding tests to new features - Goal to maintain ~100% test coverage documented ## Closes Closes #114 Closes #118 Closes #122 Closes #128 Closes #129 Closes #130 Closes #131 Closes #132 Closes #133 Closes #134 Closes #136 ## Technical Details - All new backend commands properly registered in `lib.rs` - CLI output parsing with comprehensive test coverage - Cross-platform compatibility verified through E2E tests (Linux CI can test Windows commands) - Theme-aware UI components using CSS variables throughout - Proper TypeScript types for all new stores and components - ESLint and Prettier compliant - All Clippy warnings addressed ✨ This PR was created with help from Hikari~ 🌸 Reviewed-on: #135 Co-authored-by: Hikari <hikari@nhcarrigan.com> Co-committed-by: Hikari <hikari@nhcarrigan.com>

+/**
+ * SystemClock Component Tests
+ *
+ * Note: This file tests the time formatting logic used by the SystemClock component.
+ * Full component rendering tests are challenging with Svelte 5 + @testing-library/svelte
+ * due to SSR/CSR compatibility issues. The component itself is simple and visually
+ * testable - it displays the current date and time, updating every second.
+ *
+ * What this component does:
+ * - Displays date in British format: "7 February 2026"
+ * - Displays time in 24-hour format: "14:35:42"
+ * - Updates every second via setInterval
+ * - Cleans up interval on unmount via $effect
+ *
+ * Manual testing checklist:
+ * - [ ] Clock appears above the Send button
+ * - [ ] Time updates every second
+ * - [ ] Date format is "DD Month YYYY"
+ * - [ ] Time format is "HH:MM:SS" (24-hour)
+ * - [ ] Hover effect works (border turns accent colour)
