/**
 * Strip ANSI escape sequences, remove control characters / lone surrogates,

 * Bun-native implementation of the former native `sanitizeText` (see
 * `crates/pi-natives/src/text.rs::sanitize_text`). JavaScript strings are
 * already UTF-16 code-unit arrays. `toWellFormed()` handles the uncommon
 * malformed path; when it changes the input, replacement characters are
 * dropped and the normalized result goes through the well-formed sanitizer.
 *
 * Fast path: well-formed input with no controls or ANSI returns the original
 * string after the control probe.

 * format controls that can visually reorder an otherwise safe row.
