fix(semver-lock): normalize source line endings

[worlldz]

Summary

• normalize CRLF source files to LF before computing semver-lock source hashes
• preserve the existing behavior of ignoring exactly one trailing newline
• cover both the normalization boundary and the full artifact-to-source-hash path

Why

generate-semver-lock hashes Solidity source bytes from the working tree. With no repository EOL policy, a Windows checkout using core.autocrlf=true has i/lf w/crlf Solidity files. The same commit therefore produces different sourceCodeHash values locally and in Linux CI, causing a false semver-lock diff.

Normalizing only CRLF pairs makes the hash independent of checkout configuration without changing hashes produced from the repository's LF sources.

Validation

• go test ./scripts/autogen/generate-semver-lock
• go test ./scripts/autogen/... ./scripts/checks/common
• git diff --check
