Pull Request Overview
This PR introduces comprehensive test coverage for the TypedEncoder library and makes formatting changes across the codebase. The changes include:
- Added extensive test files for TypedEncoder covering encoding types (Struct, Hash, Packed, Array, CallWithSelector, CallWithSignature, Create/Create2/Create3), nested structures, polymorphic arrays, error handling, and external usage patterns
- Implemented Create/Create2/Create3 encoding support in TypedEncoder.sol with proper validation
- Formatting changes: multi-line function signatures for improved readability
- Added documentation and test harnesses for TypedEncoder limitations with recursive types
- Updated .gitignore to exclude certain markdown files

The long conditional expressions spanning lines 203-205, 221-224, and 240-243 are difficult to read. Consider extracting these into a helper function like _validateStaticPrimitive(Primitive memory prim) to improve code clarity and reduce duplication across the three Create encoding validation blocks.

The validation logic for Create/Create2/Create3 encoding structures (lines 200, 218, 237) is highly duplicated with only the primitive count differing. Consider extracting this into a helper function _validateChunkStructure(Chunk memory chunk, uint256 expectedPrimitiveCount) to reduce code duplication and improve maintainability.
