Now those handlers do not intercept events/actions when the buffer search bar is dismissed.

To be able to trigger them from search multibuffer excerpts.

There's a deadlock that we're seeing when joining a room, which we think
is a bug in the LiveKit client.

Also, we're still getting crashes when leaving calls:
https://github.com/livekit/client-sdk-swift/issues/299.

At this point, we believe both problems are due to recent changes to the
LiveKit swift sdk.

This happens a lot in guest workflows where they open the call with a
link and are jumped straight to a shared workspace.

Release Notes:

- Fixed opening the chat automatically in new windows

This PR cleans out the README.md, moves most relevant build details to
`docs/src/developing_zed__building_zed.md`.

It also restructures and cleans up the Building Zed doc.

There are a number of outstanding TODOs to have this doc be ready for
external folks to be able to build Zed.

Here are a number of follow up tasks we need to do:

- [ ] Add CLA link
- [ ] Add public roadmap link
- [ ] Add link to channels doc once it is up
- [ ] Add link explaining how to find a channel related to your
contribution or or to create one

This PR makes the channel buttons square.

Release Notes:

- Adjusted the shape of the channel buttons.

This PR adds the `color` crate, which will be the home of a number of
color-related utilities, and also acts as an interface between
[`palette`](https://crates.io/crates/palette) and the way `gpui` colors
work.

The goal of this crate is to centralize color utilities like mixing and
blending, building color ramps and sets of colors for state and more.

## Todo:

- [x] hex -> Color
- [x] Color mixing
- [x] Color blending using blend modes (overlay, multiply, etc)
- [ ] ~~Build color ramp from color~~
- [x] Build state set from color
- [ ] ~~Update Theme to use the color crate~~

Release Notes:

- None (Internal changes: Adds the `color` crate for working with
colors.)

In #3910 we made the welcome screen use the same background color as the
editor.

However, this later regressed in
cdd5cb16ed896b2ee3bbb041983ee7cb812f6991.

This PR fixes that regression and restores the correct color for the
welcome page.

Release Notes:

- Fixed the background color of the welcome screen.

Release Notes:

- Improves the rendering of the facepile in the titlebar with many
people

Release Notes:

- Fixes a bug where you could not use call controls after a project was
unshared

Release Notes:

- Fixed a bug allowing certain UI elements to render incorrectly when
overlapping.

This removes the terminal performance slightly by removing memmoves that
aren't needed after inlining a call.

It also removes a possibly unnecessary `String` allocation.

Release Notes:

- Improved terminal rendering performance by reducing allocations and
memory operations.

Before this change we wouldn't submit all possible primitives of the
same kind that are less-than the max order.

Result was that we would submit, say, 10 paths each in a separate batch
instead of actually batching them.

This was overly strict because even if the order of two different
primitives was the same, we could have still batched the 1st primitive
kind, if its implicit ordering was less than 2nd kind.

Example: say we have the following primitives and these orders

  5x paths, order 3
  2x sprites, order 3

Previously, we would submit 1 path, 1 path, 1 path, 1 path, 1 path, then
the sprites.

With this changes, we batch the 5 paths into one batch.

Release Notes:

- Improved performance when rendering lots of selection.

This "adds" the keybindings I was missing in Vim mode (e.g. `Ctrl-[` to
cancel a selection) by fixing the definitions in the keymap from
`Ctrl+[` to `Ctrl-[`.

Release Notes:

- Fixed missing `Ctrl-[` keybindings in Vim mode where `Ctrl-[` should
act like `Esc` but didn't.

`Ctrl+[` to `Ctrl-[`.

Previously, we were using `size_of` but passing the wrong type in
(`MonochromeSprite` instead of `PathSprite`). This caused us to read
outside of the `sprites` smallvec and triggered the segfault. This
reverts #4078 because I don't think using a `SmallVec` was the issue (it
might have masked this problem though, because we would most of the time
copy from the stack and not from the heap).

With this pull request we are also fixing another potential source of
segfaults, due to checking if we exhausted the instance buffer too late
when drawing underlines.

Release Notes:

- Fixed a crash that could happen during rendering.

This PR tweaks the positioning of the mute indicators so that they cover
a little bit less of the avatar:

(It's a bit hard to tell in the screenshot, but there is a gap between
the bottom of the indicator and the top of the color ribbon).
