구현 주석

Explicit time zone selector. There is deliberately no default:

• 'UTC' — UTC wall clock (no Intl involved).
• 'device' — the runtime’s local time (no Intl involved). This is an explicit opt-in, not a silent fallback: the dependency on device state is visible at every call site.
• IANA zone name — e.g. 'Asia/Seoul'; resolved via Intl.DateTimeFormat. An unknown name throws FormatError('ERR_TIMEZONE_INVALID'). Ask {@link canFormatTimeZone} first if the runtime’s Intl is not known to be healthy.
