Re: How could they have built and launched the "Friendship one" in 206
That would be TNG's "Where No One has Gone Before" in which Data said a subspace transmission from 2.7 millon light years out should be received by Starfleet in fifty one years ten months years out before he was cut off. Which places subspace communication at approx 47 000ly per year. So about 3 years for VOY to receive a reply
Incidently Data said it would take over 300 years to get home. As he didn't say over 400 years the travel time would be 300-399 years. And at 399 years it would give a speed of 6767ly per year travel time. Which means VOY would complete her Journey in about 11 years.
...But this goes a bit deeper than that. Supposedly, by 2248, F1 had sailed out to a distance equal to that between Starfleet HQ and Janeway. Never mind comms delay - Janeway supposedly had no means of sending messages to HQ at all, either at two-second delay or two-century delay. So how come F1 did?
Another probe in Trek canon communicated from afar, too: Quadros 1 sent data from a distance of 70,000 lightyears, equal to Janeway's first-season distance from HQ and about twice that of the seventh-season distance. Although in that context (the DS9 pilot episode) we got no information about comms delay - Q1 might have sailed out millennia prior, and its findings might have taken those thousands of years to reach the Federation. Or Q1 might have been a long-base interferometry probe, never sailing to the Gamma Quadrant as such, but merely making possible telescopic observations of that distant location. F1 is a completely different issue... Especially as we know it's old Earth tech and not something built by more advanced cultures.

I seem to recall some early TNG episode were Enterprise is flung somewhere distance. I might take centuries to make it home at high warp, but subspace radio would be their a few decades.
So if the F1 probe is sending a signal back, Earth will still get a signal until is stops transmitting, even if the delay gets longer and longe as the light years increase. The signal might have stopped being received in 2248 or it might have stopped transmitting in 2248 and they stopped receiving it later. The "lost contact" could be the time it stopped, or the time they stopped getting a signal.
As for the probe remaining in warp. Warp field sustainters like the photon torpedoes have. Also the class 9 probes that are used sometimes to send single people out to starships. Get the ship to warp, then sustain that speed in a massively extended cruise via a warp bubble. Every once in a while the warp drives fire off another burst to keep the ship at warp, but for most of the time the ship just cruises. This might be fatal to humans, but the probe wouldn't care.
What is more of a puzzle is that Earth left detailed plans for building antimatter power plants in the computers of the probe in an effort to make friendly contact with other species near Earth's level of advancement. I don't recall if there was anything in there about warp drives, but a lot of antimatter technology from 2060s Earth.
