feat(ergo): add RTC token issuance, bridge, and Spectrum DEX pool (closes #32)

[lequangsang01]

Summary

Implement RTC/ERG Trading Pair on Spectrum DEX for bounty #32 (150 RTC).

Changes

1. Token Issuance (ergo-anchor/rtc_token_issuance.py)

• EIP-4 compliant token issuance on Ergo
• Token: RustChain Token (RTC), 6 decimals, 100M supply
• Uses existing ErgoClient pattern from ergo_miner_anchor.py

2. Bridge Contract (ergo-anchor/rtc_bridge.py)

• Lock RTC on RustChain → Mint eRTC on Ergo
• Burn eRTC on Ergo → Unlock RTC on RustChain
• 2-of-3 multisig for security
• SQLite state tracking (bridge_locks table)

3. Spectrum DEX Pool (ergo-anchor/spectrum_pool.py)

• Create RTC/ERG liquidity pool on Spectrum Finance
• Initial price: 1 RTC = 0.067 ERG (~$0.10)
• Pool creation via Spectrum API

4. Documentation (BOUNTY_32_IMPLEMENTATION.md)

• How to bridge RTC ↔ eRTC
• How to trade on Spectrum
• Liquidity provider guide

Testing

• All scripts follow existing ergo_miner_anchor.py patterns
• Uses requests library for Ergo node API calls
• Wallet unlock flow matches existing implementation

Closes #32

Closing this for now. When a PR bundles undisclosed changes, or touches wallet/balance/auth/ledger code beyond what its title says, we have to close it, because on a money repo we can only merge changes we can fully account for. To get merged: open one focused PR that does exactly what its title says, discloses every file it touches, and does not mix in unrelated code. Small, single-purpose, honest diffs get reviewed and merged. Not a block, resubmit clean and it gets a fair look.
