Structured Error Types

[nloding]

Problem

Error handling could be improved:

• Error::Decode uses generic String messages
• No specific errors for: corrupted move bytes, index corruption, namebase corruption, buffer overflow
• Some unwrap() and panic! calls in encoding that could be handled gracefully

Solution

1. Add specific error variants for different failure modes
2. Replace panics with proper error handling
3. Include context in errors (e.g., game number, byte offset)

Potential Panics to Address

• game.rs:200 - unwrap() on start_board
• mov.rs:82,84,108,110 - assert! calls in encode functions
• mov.rs:217,226 - panic! for invalid pawn moves

High - improves reliability and debugging
