Build MCP Server: NEAR Wallet (Read-Only) for Claude

Description

## Overview
Create a read-only MCP server for NEAR wallet operations - checking balances, viewing transactions, and exploring accounts without any write capabilities.

## Why This Matters
Many users want Claude to help them understand their NEAR activity without the risk of accidental transactions. Read-only mode provides safety.

## Technical Requirements

### Read-Only Tools
```typescript
// Tools to implement (NO write operations):

// 1. get_balance - Check any account balance
// 2. get_transactions - View transaction history
// 3. get_access_keys - List account access keys
// 4. get_staking_info - View staking/delegation status
// 5. explain_transaction - Decode and explain any tx
```

### Safety Features
- No private key handling
- No transaction signing
- Clear "read-only" indicators in responses
- Works with any public account

## Deliverables
1. **Read-only MCP server** - Published to npm
2. **Zero transaction risk** - By design
3. **Documentation** - Clear scope explanation
4. **Listed in MCP Registry**

## Budget: 8 NEAR
Simpler scope than full wallet = lower budget, faster delivery.
