1-11: Include motivation and rationale in the PR description.

The PR description is empty (contains only an unchecked template). Please add:

1. Motivation: Why upgrade to Cancun? (e.g., access to new opcodes like BLOBHASH, gas cost optimizations, alignment with network requirements)
2. Solution: What changed and why this is the right approach
3. Migration notes: Any breaking changes, behavioral differences, or developer actions required
4. Testing: Confirm that migration has been tested end-to-end

This helps reviewers understand the intent and risk of the change.

9-9: Configuration is correct and ready to merge.

The evm_version = "cancun" setting is appropriate for this codebase. This is the initial foundry.toml creation (not an upgrade), Solidity 0.8.25 supports Cancun, and the library code uses only basic EVM operations (memory access, arithmetic, bitwise logic) that remain unchanged across EVM versions. The memory-safe assembly blocks will function identically under Cancun. No special verification is needed beyond the standard test suite.
