Solana Graveyard Hackathon Revival | Track: Migrations ($7K)

This fork brings the abandoned Port Finance lending protocol back to life on modern Solana tooling. See MIGRATION.md for the full technical migration guide.

What's New

• Replaced dead Switchboard v1 oracle with deprecation stub
• 2 programs compile and BPF-build on modern toolchain
• 66/66 tests passing (token-lending program)
• New TypeScript client SDK with state decoders, instruction builders, and 52-assertion demo
• 13 migration stories completed (see MIGRATION.md)
