feat(sdk): implement Phase 1 SDKs for Wallet, RPC, and Storage

Implements comprehensive SDK support for three core services across
four programming languages (JavaScript/TypeScript, Python, Go, Rust).

## New SDKs

### Wallet SDK
- Key management (create, import, export)
- Transaction signing
- Message signing and verification
- Balance and UTXO queries
- Stealth address support

### RPC SDK
- Block and transaction queries
- Chain state information
- Fee estimation
- Mempool information
- WebSocket subscriptions for real-time updates

### Storage SDK
- Content upload and download
- Pinning operations
- CAR file support
- Directory management
- Gateway URL generation

## Shared Infrastructure

- JSON Schema definitions for all 11 services
- Common type definitions (Address, Amount, UTXO, etc.)
- Unified error handling patterns
- Builder patterns for configuration

## Package Updates

- JavaScript: Updated to @synor/sdk with module exports
- Python: Updated to synor-sdk with websockets dependency
- Go: Added gorilla/websocket dependency
- Rust: Added base64, urlencoding, multipart support

## Fixes

- Fixed Tensor Default trait implementation
- Fixed ProcessorType enum casing
