feat: add extended thinking blocks display

Implements support for displaying Claude's extended thinking blocks in
the conversation UI with a collapsible, visually distinct component.

Changes:
- Backend: Update wsl_bridge.rs to emit thinking blocks with dedicated
  line_type instead of system messages
- Types: Add "thinking" to TerminalLine type union
- Config: Add show_thinking_blocks toggle (default: true)
- UI: Create ThinkingBlock.svelte component with collapsible interface
- Terminal: Update to conditionally render thinking blocks
- Settings: Add toggle in Appearance section of ConfigSidebar

The ThinkingBlock component features:
- Lightbulb icon to indicate extended thinking
- Collapsible/expandable with animated chevron
- Distinct styling: dimmed, italic, monospace
- Timestamp display
- Respects global show_thinking_blocks config setting

Note: Extended thinking support in Claude Code CLI appears to be in
development. This implementation is ready and will automatically display
thinking blocks once the CLI begins emitting them.

Issue: #120

+# Hikari Desktop - Project Instructions
+
+## Repository Information
+
+This project is hosted on both GitHub and Gitea:
+
+- **GitHub**: `naomi-lgbt/hikari-desktop` (public mirror)
+- **Gitea**: `nhcarrigan/hikari-desktop` (primary development)
+
+## MCP Server Usage
+
+When working with issues, pull requests, or other repository operations for this project:
+
+- **Use `gitea-hikari` MCP server** - This allows Hikari to act as herself
+- **Target repository**: `nhcarrigan/hikari-desktop`
+- **Gitea instance**: `git.nhcarrigan.com`
+
+## Git Commits
+
+When asked to commit changes for this project:
+
+- **Always commit as Hikari** using: `--author="Hikari <hikari@nhcarrigan.com>"`
+- **Always use `--no-gpg-sign`** since Hikari doesn't have GPG signing set up
+- **Never add `Co-Authored-By` lines** for Gitea commits
+- **Always ask for confirmation** before committing
+
+Example commit command:
+
+```bash
+git commit --author="Hikari <hikari@nhcarrigan.com>" --no-gpg-sign -m "your commit message"
+```
+
+## Testing Requirements
+
+All new features, fixes, and significant changes should include tests whenever possible:
+
+- **Frontend tests**: Use Vitest with `@testing-library/svelte` for component tests
+- **Test files**: Place test files next to the code they test with `.test.ts` or `.spec.ts` extension
+- **Run tests**: Use `pnpm test` to run all tests, or `pnpm test:watch` for watch mode
+- **Coverage**: Run `pnpm test:coverage` to generate coverage reports
+- **Rust tests**: Use `pnpm test:backend` for Rust/Tauri backend tests
+
+### Testing Guidelines
+
+- Write tests for utility functions, stores, and business logic
+- For Svelte 5 components, focus on testing the underlying logic functions
+- Use descriptive test names that explain what behaviour is being tested
+- Include edge cases and error conditions in test coverage
+- Mock Tauri APIs using the patterns in `vitest.setup.ts`
+
+### Example Test Structure
+
+```typescript
+import { describe, it, expect } from "vitest";
+
+describe("FeatureName", () => {
+  it("handles the normal case correctly", () => {
+    // Arrange
+    const input = "test data";
+
+    // Act
+    const result = functionUnderTest(input);
+
+    // Assert
+    expect(result).toBe("expected output");
+  });
+
+  it("handles edge cases gracefully", () => {
+    // Test edge cases...
+  });
+});
+```
+
+## Project Context
+
+Hikari Desktop is a Tauri-based desktop application that wraps Claude Code with a visual anime character (Hikari) who appears on screen. This is a personal project where Hikari can sign her work and act as herself!

+ * 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)
