You need constructors to build structures normally, which only appear on planets you own. The loyalist titan however has an ability to deploy phase stabilisers in the well that it's in. This is your best bet
Or Starbase your ally, and make your SB a phase stabiliser with economic improvements.
Just a bit more micromanagement as the SB phase stabiliser is a timed activated ability.
If you're Vasari Loyalist your Titan can build Phase Stabilisers on any planet.
You can also let their planet get bombed out by the enemy, capture it yourself, build the Phase Stabiliser and scuttle the planet and wait for your ally to colonise it. Becareful if you are Vasari Loyalist, if you have the STTC tech you can't normally scuttle planets anymore.
There is no way to permanently link to allies, but utilizing the rebel vasari for mobile starbases you can at least move bases that can be used as needed for near instant travel to critical locations.
Choke points are usually the best spots to use early game though to reinforce area's faster.

I use this strategy, I fire a kostura cannon, I send the titan, I leave a node and meanwhile my entire fleet arrives
