Overview

Internal ticket

Adds the fully-qualified-name to the rendered syntax text JSON.

• This is helpful for including in things like the hover-help; but also lets us generate correct hyper-links by name, not just by hash.
• Linking by name is typically faster (due to implementation reasons) and it's a better UX to have the name in the URL rather than a hash.
• It also guarantees that the name we render actually matches the name the user clicked on (in cases where there are multiple names for a hash).
• It also allows us to know when a given hash is in a specific library by name alone, which Share can use to avoid needing to crawl through libs to find it.
• It's also less prone to breakage when linking to branch heads without a pinned causal hash. If the causal hash is pinned, then it uniquely identifies a given term.

Implementation approach and notes

Just adds a new fqn key to the JSON for TypeReference, DataConstructorReference, AbilityConstructorReference, TermReference syntax text elements. It's a little awkward it's not in contents or w/e, but can't do that and still be back-compatible. It's fine as is IMO
This value will be null if a given hash doesn't have a name in scope. Possibly also when using old cached syntax texts; but we can choose to clear the old caches if desired.

Test coverage

• Updated the output of the api transcripts.
