 * 1. Remove thousand separators (formatting, not data) - only when `thousandSeparator` is set
 * 2. Normalizing fullwidth digits (e.g., １２３ → 123)
 * 3. (Optional) Expanding compact notation (e.g., 1k → 1000)
 * 4. Expanding scientific notation (e.g., 1.5e-5 → 0.000015)
 * 5. Removing non-numeric characters
 * 6. Removing extra decimal points
 * 7. (Optional) Removing leading zeros
 * 8. (Optional) Prepend `0` before a bare leading decimal separator (.5 → 0.5)
 * 9. (Optional) Truncate raw to `maxLength` characters
 *
 * Note: Decimal separator conversion (comma ↔ dot) is handled in the beforeinput event
 * (handleOnBeforeInputNumoraInput), not here, to avoid converting thousand separators.
 *
 * `formattingOptions.thousandSeparator` doubles as a flag: pass it to strip separators,
 * leave it undefined to keep them. Callers that want to short-circuit removal (e.g.
 * formatOn === 'blur' on the typing path) should set thousandSeparator to undefined.
