We'll now add panels to the workspace as soon as they're ready rather
than waiting for all the rest to complete. We should strive to make all
panels fast, but given that their load tasks are fallible and do IO,
this approach seems more resilient.

Additionally, we'll now start loading the agent panel at the same time
as the rest.

Turns out this broke copying a screenshot from apps like CleanShot X and
then pasting it over. We should land this again after taking a look at
those cases. Pasting screenshots from the native macOS screenshot
functionality works though.

Release Notes:

- Fixed issue where copying a screenshot from apps like CleanShot X into
Agent Panel didn't work as expected.

Since the recent changes in

[https://github.com/zed-industries/zed/pull/38881](https://github.com/zed-industries/zed/pull/38881),
the filename editor is sometimes not focused after duplicating a file or
creating a new one, and similarly, autoscroll sometimes didn’t work. It
turns out that multiple calls to `update_visible_entries_task` cancel
the existing task, which might contain information about whether we need
to focus the filename editor and autoscroll after the task ends. To fix
this, we now carry that information forward to the next task that
overwrites it, so that when the latest task ends, we can use that
information to do the right thing.

Release Notes:

- Fixed an issue in the Project Panel where duplicating or creating an
entry sometimes didn’t focus the rename editing field.

We call `entry_by_path` on the `bulk_staging` anchor entry at the
beginning of `update_visible_entries`, but in the codepath where
`sort_by_path` is toggled on or off, we clear entries without clearing
`bulk_staging` or counts, causing that `entry_by_path` to do an out of
bounds index. Fixed by clearing `bulk_staging` as well.

https://github.com/zed-industries/zed/pull/40883 implemented this
incorrectly. It was marking a random background thread as a wasm thread
(whatever thread picked up the wasm epoch timer background task),
instead of marking the threads that actually run the wasm extension.

This has two implications:
1. it didn't prevent extension panics from tearing down as planned
2. Worse, it actually made us hide legit panics in sentry for one of our
background workers.

Now 2 still technically applies for all tokio threads after this, but we
basically only use these for wasm extensions in the main zed binary.

Release Notes:

- Fixed extension panics crashing Zed on Linux

The idea is that we only store running (`!self.finished`) or finished

jobs are pruned out immediately. We don't really need them in the grand

As discussed in the first responders meeting. We have collected a lot of
backtraces from these, but it's not quite clear yet what causes this.
Removing these should ideally make things a bit more stable even if we
may run into panics later one when the faulty anchor is used still.

itself
