In Shadows you would indeed use Special Forces to solve this problem - send in some Special Forces first or along with an invasion and they should disable these kinds of facilities, which would then allow bombardment. Previous to that, the only way was a full ground invasion for a shielded planet. Planetary Shields are currently impervious to bombardment (but not to planet destroyers).
Design-wise, the amount of power a planet can generate far exceeds what a ship in orbit has, that was the logic behind the strength of the planetary shield. I agree that in the long run it would be nice to make this less binary.
As a side note, espionage cannot directly target the shield (something else we should add in the future) but it can try to incite a rebellion on the colony. If it succeeds, the rebellion could damage the shield, so there is an indirect way to potentially do this through espionage, though that's unlikely to work on the Shakturi.
