/**
 * TypeScript file extension regex
 * Match .ts / .cts / .mts extensions with an optional ?query suffix.
 * Reject .tsx — and any other `.ts<letter>…` extension like .tsrx — via
 * a negative-lookahead on a following ASCII letter, so only genuine TS
 * files pass.
 *
 * Previous form `/\.[cm]?(ts)[^x]?\??/` was intended to exclude `.tsx`
 * specifically (`[^x]?` = not-an-x), but the `?` quantifier also allows
 * zero characters, and any non-`x` letter was admitted — so `.tsrx`
 * and similar extensions matched by accident.
