I have a new construction house under way (in Florida). It's still in the
rough stages (walls and roof up, plumbing and wiring mostly done, no
sheetrock yet). Today I noticed a crack (narrow, almost a "hairline"
crack) running for about 15 feet across the slab. Is it somewhat
normal/expected to have a crack in the slab, or is this a very big warning
sign that I should bring up with the builder? Thanks for information.
If you're not on the edge, you're taking up too much space.

As Don Young says, some hairline cracks are not unusual and joints of
several kinds are used to control cracking. Concrete changes volume as
it cures and if the soil is not properly prepared, can settle.
The size, shape, and location relative to other features can give
useful information on causes and severity.
As the others have said small cracks are inevitable however you may want
to fill them with rubberized caulking if they widen anymore, prior to
putting down your finish floors such as carpet. Doing so may deter ants
and such from appearing later.
