### Background
Currently, our CRDT uses three different types of timestamps:
| clock type | representation | purpose |
|-----|----------------|----------|
| `Local` | replica id + u32 | uniquely identifies operations |
| `Lamport` | replica id + u32 | provides a consistent total ordering
for all operations |
| `Global` | N local clocks | fully defines the partial ordering between
all concurrent operations |
All text operations include *each* type of timestamp. And every
`Fragment` in a buffer's fragment tree contains both a local and a
lamport timestamp.
### Change
An operation can be uniquely identified by its lamport timestamp, so we
don't really need a concept of a local timestamp. In this PR, I've
removed the concept of a local timestamp. Version vectors
(`clock::Global`) now store vectors of *lamport* timestamps.
Eliminating local timestamps reduces the memory footprint of a buffer by
four bytes per fragment, reduces the size of our `UpdateBuffer` RPC
messages, and reduces the amount of data we need to store in our
database for channel buffers. It also makes our CRDT a bit easier to
understand, IMO, because there is now only one scalar value that we
increment per replica.
It's possible I'm missing something here though. @as-cii, @nathansobo
it'd be good to get your 👀
The latter is not possible to press in Zed, since `:` is typed as
`shift-;` with typical US keyboard layouts.
In the end, it's the same buttons you have to press to toggle the inlay
hints, but working this time.

In some situations outside JSX elements Tailwind will never
respond to a completion request, holding up the tsserver completions.
Only submit the request to Tailwind when we wouldn't get tsserver
completions anyway and don't submit to Tailwind when we know we won't
get Tailwind completions
