What
When resolving an import path, Claude Code's module resolver now also tries a .mts file if the import ends in .mjs, and a .cts file if it ends in .cjs. This joins the existing mapping that tries .tsx for a .jsx import.
Why
This lets imports resolve correctly to TypeScript source files (.mts, .cts) even when the import specifier uses the compiled JavaScript extension (.mjs, .cjs).
