@agu-z and paired on trying out a "one tool call per edit" approach for
editing files. (The previous approach is still available, it's just
unchecked by default for now.)

Sometimes we've seen models provide an empty string for the path search
glob. This assumes they meant "*" when that happens.
Separately, this also removes an unnecessary `clone` of a `String`.
Release Notes:
- N/A
- Add instructions in description to read before editing
- Add instructions in edit prefix to explicitly ask for reads
- Fix `connection error: delay between messages too long` by processing
chunks off a channel
Release Notes:
- N/A
Sometimes the editor model returns no search/replace blocks. This
usually happens when the architect model calls the edit tool before
reading any files. When this happens, we'll now return the raw response
from the editor model to the architect model so it can recover
accordingly.
Release Notes:
- N/A
Instead of just reporting a search match failure, we'll now indicate
whether the file is empty or exists to help the model recover better
from bad edits.
Release Notes:
- N/A
If the tool asks to read a path, we don't need to verify whether that
path exists on disk; an unsaved buffer with that path is fine.
Release Notes:
- N/A
Sometimes the model produces SEARCH queries that don't match the
indentation of the source file exactly.
When we can't find an exact match, we'll now attempt to match the lines
while being more flexible about the leading whitespace as long as all
lines are consistently offset from the source, and extend the leading
whitespace in the REPLACE string accordingly.
Release Notes:
- N/A
This is the core change:

TODO:
- [x] Use AsyncFn instead of Fn() -> Future in GPUI spawn methods
- [x] Implement it in the whole app
- [x] Implement it in the debugger
- [x] Glance at the RPC crate, and see if those box future methods can
be switched over. Answer: It can't directly, as you can't make an
AsyncFn* into a trait object. There's ways around that, but they're all
more complex than just keeping the code as is.
- [ ] Fix platform specific code
Release Notes:
- N/A
When we failed to match a search string, we were reporting the replace
string as not found, this confuses the model and can make it go into a
doom loop. This PR fixes that improves the error output in general to
help it recover faster.
Release Notes:
- N/A
#26935 is leading to bad edits, so let's revert it for now. I'll bring
back a version of this, but it'll likely just focus on indentation
instead of making the whole search fuzzy.
Release Notes:
- N/A
When the model reads file, we'll track the version it read, and let it
know if the user makes edits to the buffer. This helps prevent edit
failures because it'll know to re-read the file before.
Release Notes:
- N/A
We'll now include the search/replace block that got applied as part of
the tool output. We think this will help the model have a better idea of
how the file changed and prevent later edit failures.
Release Notes:
- N/A
Without this, we running into the following error:
```
Running into this when running tests. Is this

Thanks Piotr!
Release Notes:
- N/A
When the user attached context in the thread, the editor model request
would fail because its tool use wouldn't be removed properly leading to
an API error.
Also, after an edit, we'd keep the old file snapshot in the context.
This would make the model think that the edits didn't apply and make it
go in a loop.
Release Notes:
- N/A
Instead of getting the whole text from the buffer, replacing with
`String::replace`, and getting a whole diff, we'll now use `SearchQuery`
to get a range, diff only that range, and apply it (all in the
background).
When we match zero strings, we'll record a "bad search", keep going and
report it to the model at the end.

Adds an `debug: edit tool` action that opens a new view which will help
us debug the edit tool internals. As the edit tool runs, the log
displays:
- Instructions provided by the main model
- Response stream from the editor model
- Parsed edit blocks
- Tool output provided back to main model
The log automatically records all edit tool interactions for staff, so
if you notice something weird, you can debug it retroactively without
having to open the debug tool first. We may want to limit the number of
recorded requests later.
I have a few more ideas for it, but this seems like a good starting
point.

Assertions on the parsed system prompt should use CRLF on Windows. I
didn't see it before because I was testing on my Windows VM from a
shared folder I cloned on macOS.
