Claude: This PR was written by Claude Code on behalf of @apiology.

Problem:

Open PRs are tested only one at a time:

castwide/solargraph PRs, each tested only against its own base

A conflict between two of them would surface only after both merge.

Solution:

Merges every PR below into one branch so CI runs on the combination.
