Project a datetime (Temporal3 [8]-[11]): apply the source’s zone to the
local (date, nanos) after component overrides. With a new timezone: a
numeric offset or named zone SHIFTS the instant when the source already had
an offset (time/datetime), else ATTACHES (interpreting the local time as
being in that zone). Without one, the source offset/zone (or UTC) is kept.
