refactor(preload): use Proxy for auto IPC routing

Replace manual IPC method mapping with Proxy-based approach.
Method names now automatically route to IPC channels,
eliminating the need to update this file when adding new APIs.

- Uses Proxy to intercept property access
- Static properties (platform) handled separately
- Supports variable argument counts via rest parameters
