Add BSC Testnet contract address registry

[Copilot]

Documents all deployed NetDAG contracts on BSC Testnet across three files for different use cases: human-readable markdown, machine-readable JSON, and JavaScript application config.

Changes

• DEPLOYED-CONTRACTS.md - Comprehensive registry with BSCScan links, contract descriptions, and network information
• config/deployed-addresses.json - Structured data for programmatic access (CI/CD, scripts, integrations)
• config/contract-config.js - Added PRESALE_CONTRACT, VESTING_VAULT, and corrected TOKEN_CONTRACT address
