Remove the event send timer in Zed 2 telemetry in effort to continue
reducing the amount of stress the vercel endpoint receives. This allows
the queues to fill up entirely before sending them off. I'm leaving the
timer in for Zed 1 because we don't force the events queue to clear on
app close in Zed 1, so it feels best to leave it in there, as it might
catch some unsent events before closing.

Release Notes:

- N/A

To avoid confusion with the way file results are matched, add a
separator between history and query matches in file finders.

Release Notes:

- N/A

* entirely remove history navigation buttons in the terminal pane that
allows terminal elements only
* hide the entire tab bar if no active item is in pane (as in zed1)
* hide +/split/zoom buttons when the pane is not in focus (as in zed1)

This PR styles the inlay hints after the changes to the themes.

This PR updates the `theme_importer` to pull in the player colors so
that we can assign them based on the current theme.

This PR applies another round of refinements to the ported Zed1 themes.

Most of this was focused around the coloration of UI text to better
match Zed1.

Give the caller of report_app_event() the choice of whether to immediately flush the queue or not.

It seems like we've fixed the clickhouse errors by switching to
`async_insert`, but we're still seeing a hiccup here and there on
vercel's socket. I slowed down the collection of cpu and memory events
earlier, and this PR will slow down how frequently we send events in
general, by increasing the queue size and the debounce time.

Release Notes:

- N/A

Fixes an issue where zoom didn't work when closing and re-opening a
zoomed panel.

This PR adjusts the sizes of the current call controls in the title bar
to be smaller.

This matches the size of the other title bar items that are always
present.

This PR adds spacing between buttons in the tab bar.

This PR adjusts the size of the tab descriptions to use the extra small
label size.

This makes it easier to distinguish between the filename and the
description:

It's also more in line with how things look in Zed1.

Fixes '"Share" button is shown even for remote projects'.

This PR maps additional text colors from the Zed1 themes to the Zed2
themes.

Release Notes:

- N/A

This PR is a first pass at porting the Zed1 themes to Zed2.

For the initial release of Zed2 we'll be shipping just the themes that
existed in Zed1, ported to Zed2. The new themes that were previously
added just in Zed2 have been removed.

Release Notes:

- N/A

1. Blocks (with their headers) and mouse listeners should be drawn
together otherwise either starts to loose mouse events.

2. Scrollbar should be above all to match zed1 look and avoid buffer
headers popping slightly to the right of the scrollbar.

This PR extends the `theme_importer` with the overall structure required
to support importing themes from Zed1.

The panic was caused by Cocoa synchronously invoking the
`selected_text_range` method on the registered input handler while we
already had a borrow of the app.

This pull request fixes this issue by showing the character palette on
the next tick of the loop (we've had this problem in other spots too and
used the same technique).

This PR disambiguates the macOS class names used in GPUI2 from the ones
used in GPUI1.

Right now if you happen to end up with a copy of both `gpui` and `gpui2`
in the dependency tree you get an unhelpful `unwrap` error when we try
to build the class names.

By giving them different names we are able to get to our more helpful
error that informs you that both GPUI1 and GPUI2 are in the module tree.

We can change these names back once we do the big "un-2-ing".

This also switches to using `Pixels` instead of `f32` to store the panel
size everywhere.

Update VCS menu to match Zed1.

We were not using `flex` on the `PaneGroup`, which caused the bottom
dock to be unable to satisfy the desired resize value.

We were not using `flex` on the `PaneGroup`, which caused the bottom
dock to be unable to satisfy the desired resize value.

This addresses a bug where popover menus in the titlebar were rendered
only after a 2nd click. The first click was creating the View which the
second one then rendered.
In addition to this, `PopoverMenu::menu` function argument can now
return an `Option<View<T>>` instead of `View<T>` as the creation of the
menu can fail (as it might in case of git popover).
