Previously the `filter` caused the diagnostics to not be attached to the
document - which is good - but the out-of-date diagnostics were still
inserted into the global (editor-wide) diagnostic set. Instead we should
completely discard out-of-date diagnostics.
There is no functional change to the move - it's just moving the code
into helix-view under a new method `Editor::handle_lsp_diagnostics` -
thought there is a typo fix, the removal of an unnecessary clone (for
the document's language config) and the removal of some nesting.

We do not highlight `(ERROR)` nodes since the highlighting is quite
noisy while typing. Also see todo comments in `syntax.rs` - we could
introduce configuration in the future to prepend `(ERROR)` to a
language's highlights query.
This matches <https://redirect.github.com/helix-editor/helix/pull/4852>
for the DAP transport: when there is a failure to receive a message from
the debugger we should drain all pending requests and respond to them
with the StreamClosed error.
This improves the behavior when a debugger fails to initialize, for
example starting debugpy without debugpy installed. Previously the UI
would freeze until the request timed out. Now it instantly prints a
statusline error saying that the debugger failed to start up.
`reader` is already a `BufReader` so there's no need to wrap it in
another `BufReader`. This is a typo/mistake made possible by the type
erasure (a `Box<BufReader<BufReader<T: Read>>>` is also a boxed reader).
By default this is `Stdio::inherit` which sends stderr from the child
process to Helix. Instead we should use `Stdio::piped` which allows us
to read the piped output.
We can also expect that the stderr opens now (it should similarly to
stdout), so that we always start a reader for stderr like the LSP
client.
This causes the infobox to disappear even when you type a non-character
key like escape. For example `"<esc>` now clears the infobox where
before it was left hanging.
You may pass constants as type arguments the const generics feature.
This is used in spellbook for example as a poor man's enum, for example
`self.strip_suffix_only::<FULL_WORD>(word, hidden_homonym)`. With this
change that `FULL_WORD` part is highlighted as a constant instead of
a type.
This change also highlight the underscore in type placeholders - this
is similar to the highlighting done for bindings in Elixir or Erlang
for example. In `Vec<_>` the underscore is highlighted the same as a
comment.
Path completion items always have documentation but future core (i.e.
non-LSP) completions may not always have documentation - for example
word completion from the current buffer.
This will replace the `Sender<CompletionEvent>` in the child commits.
It tracks sender alongside extra metadata about the responses received
from providers - namely whether a request is incomplete or not - which
can be reused between subsequent requests to the provider.
Completions are not specific to LSP anymore. In the child commits we
will expand on the types in this module so this refactor is done
eagerly to minimize changes later.
This is a similar change to the parent commit but for `request`. The
requests should be sent eagerly so that the ordering stays consistent.

Previously LSP notifications were sent within a future and most callers
used a `tokio::spawn` to send the notification, silently discarding any
failures like problems serializing parameters or sending on the channel.
It's possible that tokio could schedule futures out of intended order
though which could cause notifications where order is important, like
document synchronization, to become partially shuffled. This change
removes the future wrapper and logs all internal failures.
Also included in this commit is the same change for `Client::reply`
which was also unnecessarily wrapped in a future.
