Honestly I hope the unlimited teleportation doesn't get explained as telepresence. In fact this shouldn't be explained at all.
And this is coming from a guy who fought for logic in the fighter construction and use as well as time delayed ship transfers.
We've come to a divide. if we can telepresence across the galaxy to control a fighter, why leave your sofa to make billions? Why can fighters only telepresence 30k away from the mothership that is 30KLY away from the pilot?
I've long suggested that we can CQC from our ship regardless of distance, but explained it in a Call of Duty find of way. All the combatants are running the same sim program, contained locally, and only tiny bits of data such as ship position and weapons fire need to be constantly transmitted (using whatever quantum entanglement that allows us to talk to one another in real time regardless of distance). Bits of data, at most. But that no longer holds when you consider that you need full sensory input being transmitted in real time for this kind of crew immersion.
Anyway, I fully approve of the mechanic. It's completely necessary in the name of fun and accessibility. I'm just saying from a lore point of view NO explanation should be attempted. Accept it for what it is and just leave it up to the players to explain it to themselves if they want to. If it bugs you, dock at a station first and assume you hopped a shuttle to meet up with you buddy or take on that crewman job. If you can't dock, assume it's not you on that ship. Take a break from being you and be someone else. Whatever floats your boat.
But I dont see a satisfactory lore explanation arising from this, so don't bother trying
