So I know about /c/community@example.host for communities and /u/user@example.host for users, but how do I link to individual posts in a way that won't be a hassle for people in other instances?

UUIDs are a computer science concept where you use some math and some black magic to guarantee that you have generated a unique identifier, even in an environment with federation. This concept predates the fediverse since this is needed for lots of different use-cases. Basically anything with horizontal scaling, orchestration, or p2p needs something like this in order to prevent collisions.
