chore: switch bimm-contracts to crates.io and enable LTO in release profile

- Updated `bimm-contracts` to use crates.io registry instead of git-based dependency.
- Enabled Link Time Optimization (LTO) in Cargo release profile for improved performance.
- Removed unused `TensorDescription` struct from `bimm-firehose-image`.
