CngxTrim

Normalizes whitespace and Unicode form on blur.

Place on the <input> or <textarea>. On blur it Unicode-NFC-normalizes the value, optionally collapses internal whitespace runs to a single space (cngxTrimCollapse), and trims the ends. When the value changes it writes back and dispatches a native input event, so a bound [field] / CngxInput sees the normalized value through the existing DOM->signal path - this is a deliberate imperative DOM normalizer, not a second managed copy.

Kept separate from CngxInputFormat so a format/parse atom is not overloaded with normalization (Pillar 3).

<input cngxInput cngxTrim [field]="f.name" />
<textarea cngxTrim cngxTrimCollapse [field]="f.bio"></textarea>
