feat: Implement Moonbeam-style OpenGov governance (#131)
## 🎯 Overview

This PR implements a comprehensive Moonbeam-inspired OpenGov (Gov2)
governance system across all DataHaven runtime environments (Stagenet,
Testnet, and Mainnet). The implementation provides multi-track
referenda, conviction voting, collective decision-making through dual
councils, and complete benchmarking support.

##  Key Features

### 🗳️ Multi-Track Referendum System
Implements **6 distinct governance tracks** with different thresholds
and parameters:

| Track | Purpose |
|-------|---------|
| **Root (0)** | Critical runtime upgrades |
| **Whitelisted Caller (1)** | Fast-tracked technical proposals |
| **General Admin (2)** | General governance proposals |
| **Referendum Canceller (3)** | Cancel dangerous referenda |
| **Referendum Killer (4)** | Emergency removal of malicious referenda |
| **Fast General Admin (5)** | Expedited administrative decisions |

### 🏛️ Dual Council Structure
- **Technical Committee**: Manages technical proposals with fast-track
powers
- **Treasury Council**: Oversees treasury spending with shorter motion
duration

### 🔐 Custom Origins System
5 specialized permission levels for granular governance control:
- `GeneralAdmin`
- `ReferendumCanceller`
- `ReferendumKiller`
- `WhitelistedCaller`
- `FastGeneralAdmin`

### ⚖️ Conviction Voting
- Vote multipliers from 0.1x to 6x based on lock duration
- Delegation support for proxy voting
- Maximum 20 concurrent votes per account

🤖 Implementation assisted by [Claude Code](https://claude.ai/code)
