The changes align the project with the 2025.0.0 lsprotocol release, removing the old backport and updating type hints in the protocol hooks to use Sequence where appropriate. The dist-info and packaging metadata for older lsprotocol versions are replaced with the new 2025.0.0 artifacts. - Remove exceptiongroup backport used on Python <3.11 - Use Sequence instead of List in LS protocol hooks - Replace old dist-info with 2025.0.0 metadata
