I suspected the the return spring in the clutch master cylinder. We depressed the clutch and sprayed the internals of CMC piston assembly (located above the gas pedal) with TriFlow, and that has eliminated the clutch squeak completely in the short term. We'll see how long that lasts, may switch to other grease product if needed, or replace CMC, or both. IIRC, some dealers had suggested this as a possible cause of squeaks; In my case that was it. Can't hurt to have lubricated the clutch fork pivot too. Both these procedures are easy maintenance items.
I am puzzled. The only metal to metal contact should be between the piston and the pushrod. Is the foot in that pushrod able to float off center? I'm checking that for myself. :/

Were you able to confirm the squeak when operated by hand?
