Changes

New icon support

Layer / File(s)	Summary
Define and validate the NEW icon elementary/messages/blocks.py, elementary/messages/formats/unicode.py, tests/unit/messages/formats/*/fixtures/*	The public Icon enum includes NEW = "new". Unicode formatting maps it to 🆕. All format fixtures include the new icon.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🔵 Low · up to 1f167

The icon addition is otherwise localized, but the updated HTML fixture may fail HTML linting because it begins with a div; align the formatter and fixture on a doctype or configure fragment linting before merge.

Resolve the HTMLHint doctype-first error.

Line 1 starts with a <div>, and HTMLHint reports this as an error. If this is a complete document, add <!DOCTYPE html> to both the formatter output and this fixture. If the formatter intentionally emits an HTML fragment, exclude these fixtures from doctype-first or configure HTMLHint for fragments. Do not add the doctype only to the fixture.
