fix: comprehensive agent tracking and cleanup improvements

This commit fixes all 4 reported agent tracking bugs and adds comprehensive test coverage:

**Bug Fixes:**
1. Agents stuck in "running" state after completion
   - Added SubagentStop hook parsing in wsl_bridge.rs
   - Emits claude:agent-end events when SubagentStop hooks detected
   - Includes 8 new Rust tests for hook parsing

2. Agents persisting after disconnect
   - Added clearConversation() call on disconnect in tauri.ts
   - Prevents agents from persisting across sessions

3. "Kill All" button doing nothing
   - Added markAllErrored() call in AgentMonitorPanel after interrupt
   - Updates UI state immediately after killing process

4. Badge persisting after closing tab
   - Added clearConversation() call in conversations.ts deleteConversation()
   - Properly cleans up agent tracking when tab is closed

**Test Coverage:**
- Added comprehensive agents.test.ts with 24 new tests
- Tests all store methods: addAgent, updateAgentId, endAgent, markAllErrored, clearCompleted, clearConversation, runningAgentCount
- Added 8 Rust tests for SubagentStart/Stop hook parsing
- All 387 frontend tests pass
- All 426 backend tests pass

**Documentation:**
- Updated CLAUDE.md with comprehensive testing guidelines
- Documents coverage goals, console mocking strategies, and E2E integration testing patterns

✨ This fix was implemented with help from Hikari~ 🌸

+## 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`
+- **Coverage Goal**: Maintain as close to 100% test coverage as possible across the entire codebase
+
+### Mocking Strategies
+
+#### Console Mocking
+
+When testing code that intentionally logs errors (like error handling paths), mock console methods to prevent stderr output that makes tests appear flaky:
+
+```typescript
+it("handles errors gracefully", async () => {
+  const consoleErrorSpy = vi.spyOn(console, "error").mockImplementation(() => {});
+
+  // Test error handling code
+  await expect(functionThatLogs()).rejects.toThrow();
+
+  // Verify error was logged
+  expect(consoleErrorSpy).toHaveBeenCalledWith("Expected error:", expect.any(Error));
+
+  // Restore console.error
+  consoleErrorSpy.mockRestore();
+});
+```
+
+#### E2E Integration Testing for Cross-Platform Code
+
+For code that calls platform-specific system APIs (like Windows PowerShell or Linux notify-send), use helper functions that build the command structure without execution. This allows CI to verify cross-platform compatibility on Linux-only containers:
+
+```rust
+/// Build notify-send command for testing (doesn't execute)
+#[cfg(test)]
+fn build_notify_send_command(title: &str, body: &str) -> (String, Vec<String>) {
+    (
+        "notify-send".to_string(),
+        vec![
+            title.to_string(),
+            body.to_string(),
+            "--urgency=normal".to_string(),
+            "--app-name=Hikari Desktop".to_string(),
+        ],
+    )
+}
+
+#[test]
+fn test_e2e_notify_send_command_structure() {
+    let (command, args) = build_notify_send_command("Test Title", "Test Body");
+
+    assert_eq!(command, "notify-send");
+    assert_eq!(args.len(), 4);
+    assert_eq!(args[0], "Test Title");
+    assert_eq!(args[1], "Test Body");
+}
+```
+
+This approach:
+
+- Verifies command structure, argument order, and escaping logic
+- Tests cross-platform code paths without requiring the target platform
+- Allows CI to catch regressions in Windows-specific code whilst running on Linux
+- Keeps tests fast and deterministic (no actual system calls)
+
+### 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...
+  });
+});
+```
+
+### Adding Tests for New Features
+
+When developing new features, always add corresponding tests:
+
+1. **Before implementing**: Consider what needs testing (happy path, edge cases, errors)
+2. **During implementation**: Write tests alongside the code
+3. **After implementation**: Run `pnpm test:coverage` to verify coverage remains high
+4. **Before committing**: Ensure `check-all.sh` passes (includes all tests)
+
+The goal is to maintain our near-100% coverage as the codebase grows, so future refactoring and changes can be made with confidence!

 ## 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)
