Ruby 4.0.1 + publishable platform gems for Ruby 4.0#154
Merged
Conversation
Use .ruby-version as the single source of truth for typecheck and release jobs, and add a CI job that runs the suite on the pinned patch version.
Install the compiled extension into lib/code_ownership/<major.minor>/ so cross-gem can package multiple Ruby minors into a single platform gem without overwriting.
Exclude tmp/ and target/ from static analysis to avoid scanning vendored/compiled build outputs.
Only ignore lib/code_ownership/<major.minor>/ so new Ruby source files under lib/code_ownership/* aren't accidentally hidden.
This gem ships native binaries through Ruby 4.0, so restrict installs to < 4.1.dev until we add 4.1 builds and CI coverage.

Summary
.ruby-version.lib/code_ownership/<major.minor>/so platform gem builds can package multiple Ruby minors (3.2-4.0) without overwriting.Why
Previously published platform gems carried an unintended
required_ruby_version < 3.5.dev, blocking Ruby 4 installs. Versioned native extension paths enable building a single platform gem that contains per-Ruby-minor binaries, so the published artifact can safely support Ruby >= 3.2 (including 4.0).Test plan
