deps: update lucide-svelte to 0.564.0

## Summary

Fixes the memory files tab showing as empty on Windows production builds and the "forbidden path" error when trying to read memory files.

## Changes

### 1. List memory files from WSL home directory (commit 1)
- Split `list_memory_files()` into platform-specific implementations
- **Windows**: Use WSL command with `bash -l` to find memory files in WSL home (`~/.claude/projects/.../memory/`)
- **Linux/Mac**: Continue using native filesystem access
- Previously used `dirs::home_dir()` which returns Windows home (`C:\Users\...`), but Claude Code stores files in WSL home

### 2. Use backend command for reading files (commit 2)
- Changed frontend from Tauri's `readTextFile` plugin to `read_file_content` backend command
- Tauri plugin enforces scope restrictions and can't access WSL paths on Windows
- Our backend command already handles WSL paths correctly via `read_file_via_wsl()`
- Matches the pattern used throughout the app for other file operations

## Testing

- ✅ All 426 backend tests pass
- ✅ All frontend tests pass
- ✅ Lint, format, and type checks pass
- ✅ Follows existing WSL file operation patterns in codebase

## Related Issues

Fixes the memory files tab functionality on Windows whilst maintaining full compatibility with Linux/Mac.

+# 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`
+- **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!
+
+## 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!
+
