PyuvisCalModel

Derive the cal factor from pyuvis (build path) — not wired yet.

PyuvisCalModel()

Will read the archived PDS cal matrix via pyuvis (UVPDS / cal matrix x CORE_MULTIPLIER -> kR). Thin glue; only exercised once real PDS data is wired through PyuvisSource. pyuvis is imported lazily so the rest of the core has no hard pyuvis/cal-data dependency.

Open question (2026-09-14): the archive stream is meant to take calibration input from the new metadata as well as from the PDS cal matrix. Which quantities come from where is not yet settled, so this may grow a second input rather than staying pure pyuvis glue.
