Add OP_NET (Bitcoin L1) feasibility study

[TaprootFreak]

Summary

• Complete technical feasibility study for deploying JuiceDollar on OP_NET (Bitcoin L1 smart contract platform)
• Covers platform capabilities, critical analysis of WBTC trust model, challenge mechanism viability, and peg stability
• Identifies three fundamental blockers and proposes solutions for each
• Provides four actionable options with technical trade-offs

Key Findings

• Smart contract logic is ~85% portable (AssemblyScript/WASM has all required primitives)
• WBTC on OP_NET is controlled by a single-key custodian (no multisig, no timelock, no proof-of-reserve)
• Challenge mechanism has 60x coarser price discovery on 10-minute blocks and is economically unviable at low TVL
• No peg stabilization possible without stablecoins on OP_NET
• Recommendation: Wait for OP_LINK trustless bridge and OP-20S stablecoins before active development
