Build MCP Server: NEAR Wallet (Python) for Claude

Description

## Overview
Create a Python-based MCP server for NEAR wallet operations, for developers who prefer Python tooling.

## Why This Matters
Many AI/ML developers work primarily in Python. A Python MCP server integrates better with their existing workflows.

## Technical Requirements

### Python Implementation
```python
# MCP server using Python SDK
from mcp import Server, Tool

class NEARWalletServer(Server):
@tool
async def get_balance(self, account_id: str) -> dict:
"""Check NEAR account balance"""
...

@tool
async def send_near(self, to: str, amount: str) -> dict:
"""Send NEAR (requires confirmation)"""
...
```

### Features
- Full wallet operations (create, send, receive)
- Python-native implementation
- Async support
- Type hints throughout

## Deliverables
1. **Python MCP server** - Published to PyPI
2. **All standard wallet operations**
3. **Python-idiomatic API**
4. **Documentation with Python examples**

## Budget: 12 NEAR
