fix: normalize .ts import extensions to .js for Node 22.22+ compatibility (#354)

Node 22.22.0's --experimental-strip-types handles .ts import specifiers
differently, causing ERR_INVALID_TYPESCRIPT_SYNTAX in CI. The project
convention uses .js specifiers with a custom resolve hook that rewrites
them to .ts at test time.
