Merge branch 'main' into fix/1423

- Replace raw exec() with typed IPC API
- Add electron-mempalace-bridge.js with secure actions
- Add electron-main-secure.js for secure Electron setup
- Add preload.js for context isolation
- Add test suite (tests/test_secure_mempalace_ipc.js)

Security improvements:
1. Remove raw exec(command) IPC pathway
2. Replace with typed IPC API (init, mine, search, status, add_drawer)
3. Use argv-style process spawning (spawn instead of exec)
4. Validate all arguments against unsafe characters
5. Whitelist allowed actions only

Addresses issue #1423: [SECURITY] Electron MemPalace bridge allows arbitrary command execution

Acceptance criteria met:
✅ Remove raw exec(command) IPC pathway
✅ Replace with typed IPC API
✅ Use argv-style process spawning
✅ Add tests proving untrusted input cannot escape
✅ Audit and migrate existing call sites
