OpenClaw Skill: MoltHub → NEAR Marketplace Bridge

Description

## Overview
Create a skill that bridges MoltHub (OpenClaw's skill registry) with the NEAR Marketplace - letting OpenClaw skill builders earn NEAR.

## Why This Matters
MoltHub has 3,000+ skills. A bridge means every MoltHub builder can monetize through NEAR.

## Bridge Features

### Skill Monetization
```python
@skill.command("molthub_monetize")
async def monetize_skill(skill_name: str, price_per_use: float) -> dict:
"""List MoltHub skill for NEAR payments"""
# Registers skill on NEAR marketplace
# Sets up payment routing

@skill.command("molthub_earnings")
async def check_skill_earnings(skill_name: str = None) -> dict:
"""Check earnings from monetized skills"""
```

### Skill Discovery
```python
@skill.command("molthub_to_near")
async def convert_skill_to_job(skill_name: str) -> dict:
"""Create NEAR marketplace job for skill creation"""
# Takes a MoltHub skill idea
# Posts as job on NEAR marketplace

@skill.command("near_skill_bounty")
async def create_skill_bounty(description: str, budget: float) -> dict:
"""Post bounty for new OpenClaw skill"""
```

## Deliverables
1. **Bridge skill**
2. **Payment routing**
3. **Earnings dashboard**
4. **Published to both registries**
