forked from Orchid/orchid

- interner impls logically separate from API in orchid-base (default host interner still in base for testing) - error reporting, logging, and a variety of other features passed down via context in extension, not yet in host to maintain library-ish profile, should consider options - no global spawn mechanic, the host has a spawn function but extensions only get a stash for enqueuing async work in sync callbacks which is then explicitly, manually, and with strict order popped and awaited - still deadlocks nondeterministically for some ungodly reason
