chore: bump version to 0.3.0

This release introduces breaking changes by removing server-side validation
logic from the SDK. Server-side validation should now be handled using the
init-data-rs crate.

Breaking changes:
- Removed validate_init_data module
- Removed ValidationKey enum
- Removed TelegramWebApp::validate_init_data() method
- Removed verify_init_data_hash() function
- Removed crypto dependencies (hmac-sha256, hex, base64, ed25519-dalek)
