Subject: [PATCH] fix: add missing CLAUDE.md REST API routes in web server

When Tauri invoke fails (e.g., paths with spaces/special chars on iCloud
Drive), the frontend falls back to REST API mode. The CLAUDE.md endpoints
were mapped in apiAdapter.ts but had no corresponding handlers in
web_server.rs, causing the fallback to also fail with "Failed to load
CLAUDE.md files".

Adds three GET route handlers:
- /api/claude-md?projectPath=...  (find CLAUDE.md files)
- /api/claude-md/read?filePath=... (read a CLAUDE.md file)
- /api/claude-md/save?filePath=...&content=... (save a CLAUDE.md file)

Fixes #444
