Subject: fix(tsgo): prefer local node_modules binary over global #4258

Convert the cmd from a static array to a function that checks for a
locally installed tsgo binary in node_modules/.bin/ before falling
back to the global installation. This ensures projects using
@typescript/native-preview as a local dependency will use the correct
version, matching the pattern already used by biome.
