release: v1.6.0

## Summary

### New Features
- **Claude Sonnet 4.6 support** — added `claude-sonnet-4-6` as a selectable model in the config sidebar
- **Anime girl characters for subagents** — each subagent in the agent monitor is automatically assigned one of six characters (Amari, Keiko, Minori, Reina, Tatsumi, Yumiko) with a unique name, CDN avatar, title, and lore-flavoured description; assignment avoids duplicates when possible
- **"Meet the Team" cast panel** — a new modal accessible from the status bar introduces the full cast: Naomi (Chief hEx-ecutive Officer), Hikari (Chief Operating Officer), and the six subagent girls with their C-suite titles and character bios

### Bug Fixes
- **"Already running" error on invalid working directory** — if a spawned Claude process exits unexpectedly (e.g. because the working directory doesn't exist), `try_wait()` now detects the stale handle and clears it before allowing a restart
- **Working directory pre-validation** — on Windows, the app now runs `wsl -e test -d <dir>` before launching Claude; invalid directories surface a clear error immediately
- **WSL binary detection** — on Windows, `wsl -e bash -lc "which claude"` is used to probe for the Claude binary inside WSL; on Linux/WSLg, `bash -lc "which claude"` is used as a login-shell fallback so GUI apps find the binary even without shell PATH
- **WSL detection fix for production builds** — `detect_wsl()` now short-circuits at compile time on Windows targets, preventing inherited `WSL_DISTRO_NAME` env vars from misrouting native Windows binaries through the Linux code path

 - 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)

+### 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!
+
+## Quality Assurance
+
+Before committing any changes, **always run the full test suite**:
+
+```bash
+./check-all.sh
+```
+
+This script runs all checks in the correct order:
+
+1. Frontend linting (ESLint)
+2. Frontend formatting (Prettier)
+3. Frontend type checking (svelte-check)
+4. Frontend tests with coverage (Vitest)
+5. Backend linting (Clippy with strict rules)
+6. Backend tests with coverage (cargo test + llvm-cov)
+
+**Important**: The script requires Node.js and Rust toolchains to be available:
+
+- **Node.js tools** (pnpm, npm): Source nvm first if needed: `source ~/.nvm/nvm.sh`
+- **Rust tools** (cargo, clippy): Should be in PATH via `~/.cargo/bin/`
+
+If `check-all.sh` reports any failures:
+
+1. Read the error messages carefully - they usually explain what needs fixing
+2. Fix the issues (linting errors, test failures, etc.)
+3. Run `check-all.sh` again to verify the fixes
+4. Only commit once all checks pass ✨
+
+**Never commit code that doesn't pass `check-all.sh`** - this ensures code quality and prevents broken builds!
