Release Notes:

- Fixed the alignment of the assistant headers and text
- Increased the left padding on the assistant.

Since the message headers are buttons, we need to shift them relatively to
compensate for the fact that the background is only visible when hovered.
I'm ok with the background not being aligned so long as the unhovered text is.

Release Notes:

- Restored collab button tooltips, made screenshare item background of
editor background's color

Starting work on the following tests.

* The first failure was caused by not properly dropping the references,
which is now fixed.
* The next failure is caused by a `cx.after_window_update` being changed
to `cx.on_next_frame`. This doesn't seem to work (at least in tests),
but might also explain the flaky following behavior Max and I observed
if there's a timing bug in production too.
* * When you are following someone and they move their cursor you should
receive two proto messages: UpdateBuffer to move the cursor, and
UpdateFollowers to update where you're following. It seems like this
could be made a bit less chatty/fragile, but probably out of scope for
this.
* With that worked around, there's one more failure, but I haven't
looked into it yet. (possibly caused by an incorrect fix for the cx
one).

* Fix an incorrect use of `Any::type_id` that prevented the disabling of
key bindings
* Restructured the representation of disabled key bindings so that they
handle context predicates correctly. Previously, to disable key binding,
you needed to supply the exact same context predicate (e.g. `Editor &&
mode == "full"`) as the binding that you are trying to disable. Now, the
context predicates of disabled key bindings are evaluated just like any
other context predicate (with the current context) to see if they apply.

Release Notes:

- Fixed an issue where disabling key bindings didn't work. To disable a
key binding, set it to `null` in your keymap.

This PR tidies up the styling of the connection status indicators in the
title bar.

Removed some debug styles and tweaked the styling to match the rest of
the title bar overall.

Bugs from the 0.34.0 collab nightly deploy

This PR fixes a panic that would occur when trying to submit feedback
while within a shared project.

There may be a way we want to support this in the future, but for now we
just show a toast letting the user know this is not supported:

shared project.

This PR removes the old typescript-based theme system, and it's related
functions.

TODO:
- [x] Create standalone repo of old theme system in case it is needed.
  - https://github.com/zed-industries/zed1-styletrees
- [x] Remove `styles`
- [x] Remove licenses generating code related to `styles`
- [x] Remove docs related to old theme system
- [x] Add license generation to new theme system (#3917)
- [x] Check as best possible that all the places we were accessing
`styles` are removed or updated.

Note: For now, the JSON files in `assets/themes` will remain until we
are finished with the Zed 1 theme importer. We should be able to remove
those in the next few weeks.

Release Notes:

- N/A

This PR updates the diagnostic popovers to use the regular editor text
color rather than one specific to the diagnostic kind.

Release Notes:

- Updated text color in diagnostic popovers.

This PR decouples the generation of licenses for the themes we ship from
the TypeScript theme definitions.

For now, we are embedding the license information for the themes in the
`theme_importer`, and emit a combined `LICENSES` file in the `theme`
crate whenever we import themes. This is also where we check that each
theme has a valid license.

We then use this `LICENSES` file when building up the global license
file for Zed.

This decoupling is one step towards us being able to delete the old Zed1
styles.

Release Notes:

- N/A

This removes one of the path dependencies in gpui that's only really
needed by `workspace` (which can work around lack of these
implementations by itself). In theory it should also improve build
scheduling (as gpui doesn't have to wait for main dependency of sqlez -
libsqlite3 - to finish it's 25 seconds-long build in release), though in
practice I didn't notice a substantial improvement.
Moreover `sqlez` was unused by `settings` too, so that's removed
as well.

Release Notes:

- N/A

According to
https://docs.digitalocean.com/products/kubernetes/how-to/configure-load-balancers/#ssl-certificates

you can specify whether to disable automatic DNS record
creation for the certificate upon the load balancer’s creation using the
do-loadbalancer-disable-lets-encrypt-dns-records annotation. If you
specify true, we will not automatically create a DNS A record at the
apex of your domain to support the SSL certificate.

Release Notes:

- Fixed current LSP logs menu item not shown as selected

This PR upgrades our version of `ctor` to v0.2.6.

We were previously using a fork that contained this fix:
https://github.com/mmastrac/rust-ctor/pull/295.

A new version of `ctor` has now been released with that change, so we
can switch back to the mainline version.

I scanned through the diff between versions (since we're upgrading from
effectively v0.1.20) and didn't notice anything that seemed obviously
breaking:
