fix: Use rustls instead of aws-lc for Windows compatibility

- Switch AWS SDK to use rustls TLS backend instead of aws-lc
- aws-lc-sys has path length issues on Windows with deep directories
- Use shorter CARGO_TARGET_DIR (D:\t) to avoid path length limits
- Disable incremental compilation to reduce build complexity
