onboarding ui: Add theme preview tiles and button functionality to basic page (#35413)
This PR polishes and adds functionality to the onboarding UI with a
focus on the basic page. It added theme preview tiles, got the Vim,
telemetry, crash reporting, and sign-in button working.

The theme preview component was moved to the UI crate and it now can
have a click handler on it.

Finally, this commit also changed `client::User.github_login` and
`client::UserStore.by_github_login` to use `SharedStrings` instead of
`Strings`. This change was made because user.github_login was cloned in
several areas including the UI, and was cast to a shared string in some
cases too.

title_bar: Show the plan from the CloudUserStore (#35401)
This PR updates the user menu in the title bar to show the plan from the
`CloudUserStore` instead of the `UserStore`.

We're still leveraging the RPC connection to listen for `UpdateUserPlan`
messages so that we can get live-updates from the server, but we are
merely using this as a signal to re-fetch the information from Cloud.

agent: Fix issues with usage display sometimes showing initially fetched usage (#33125)
Having `Thread::last_usage` as an override of the initially fetched
usage could cause the initial usage to be displayed when the current
thread is empty or in text threads. Fix is to just store last usage info
in `UserStore` and not have these overrides

Release Notes:

- Agent: Fixed request usage display to always include the most recently
known usage - there were some cases where it would show the initially
requested usage.

Use anyhow more idiomatically (#31052)
https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.

The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.

The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.

* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`

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.

Eliminate GPUI View, ViewContext, and WindowContext types (#22632)
There's still a bit more work to do on this, but this PR is compiling
(with warnings) after eliminating the key types. When the tasks below
are complete, this will be the new narrative for GPUI:

- `Entity<T>` - This replaces `View<T>`/`Model<T>`. It represents a unit
of state, and if `T` implements `Render`, then `Entity<T>` implements
`Element`.
- `&mut App` This replaces `AppContext` and represents the app.
- `&mut Context<T>` This replaces `ModelContext` and derefs to `App`. It
is provided by the framework when updating an entity.
- `&mut Window` Broken out of `&mut WindowContext` which no longer
exists. Every method that once took `&mut WindowContext` now takes `&mut
Window, &mut App` and every method that took `&mut ViewContext<T>` now
takes `&mut Window, &mut Context<T>`

Not pictured here are the two other failed attempts. It's been quite a
month!

Tasks:

- [x] Remove `View`, `ViewContext`, `WindowContext` and thread through
`Window`
- [x] [@cole-miller @mikayla-maki] Redraw window when entities change
- [x] [@cole-miller @mikayla-maki] Get examples and Zed running
- [x] [@cole-miller @mikayla-maki] Fix Zed rendering
- [x] [@mikayla-maki] Fix todo! macros and comments
- [x] Fix a bug where the editor would not be redrawn because of view
caching
- [x] remove publicness window.notify() and replace with
`AppContext::notify`
- [x] remove `observe_new_window_models`, replace with
`observe_new_models` with an optional window
- [x] Fix a bug where the project panel would not be redrawn because of
the wrong refresh() call being used
- [x] Fix the tests
- [x] Fix warnings by eliminating `Window` params or using `_`
- [x] Fix conflicts
- [x] Simplify generic code where possible
- [x] Rename types
- [ ] Update docs

### issues post merge

- [x] Issues switching between normal and insert mode
- [x] Assistant re-rendering failure
- [x] Vim test failures
- [x] Mac build issue

Require accepting ToS when enabling zeta (#23255)
Note: Design hasn't been reviewed yet, but the logic is done

When the user switches the inline completion provider to `zed`, we'll
show a modal prompting them to accept terms if they haven't done so:


https://github.com/user-attachments/assets/3fc6d368-c00a-4dcb-9484-fbbbb5eb859e

If they dismiss the modal, they'll be able to get to it again from the
inline completion button:


https://github.com/user-attachments/assets/cf842778-5538-4e06-9ed8-21579981cc47

This also stops zeta sending requests that will fail immediately when
ToS are not accepted.

Allow filling co-authors in the git panel's commit input (#23329)
https://github.com/user-attachments/assets/78db908e-cfe5-4803-b0dc-4f33bc457840


* starts to extract usernames out of `users/` GitHub API responses, and
pass those along with e-mails in the collab sessions as part of the
`User` data

* adjusts various prefill and seed test methods so that the new data can
be retrieved from GitHub properly

* if there's an active call, where guests have write permissions and
e-mails, allow to trigger `FillCoAuthors` action in the context of the
git panel, that will fill in `co-authored-by:` lines, using e-mail and
names (or GitHub handle names if name is absent)

* the action tries to not duplicate such entries, if any are present
already, and adds those below the rest of the commit input's text

Concerns:

* users with write permissions and no e-mails will be silently omitted
— adding odd entries that try to indicate this or raising pop-ups is
very intrusive (maybe, we can add `#`-prefixed comments?), logging seems
pointless

* it's not clear whether the data prefill will run properly on the
existing users — seems tolerable now, as it seems that we get e-mails
properly already, so we'll see GitHub handles instead of names in the
worst case. This can be prefilled better later.

* e-mails and names for a particular project may be not what the user
wants.
E.g. my `.gitconfig` has
```
[user]
    email = mail4score@gmail.com

# .....snip

[includeif "gitdir:**/work/zed/**/.git"]
    path = ~/.gitconfig.work
```

and that one has

```
[user]
    email = kirill@zed.dev
```

while my GitHub profile is configured so, that `mail4score@gmail.com` is
the public, commit e-mail.

So, when I'm a participant in a Zed session, wrong e-mail will be
picked.
The problem is, it's impossible for a host to get remote's collaborator
git metadata for a particular project, as that might not even exist on
disk for the client.

Seems that we might want to add some "project git URL <-> user name and
email" mapping in the settings(?).
The design of this is not very clear, so the PR concentrates on the
basics for now.

When https://github.com/zed-industries/zed/pull/23308 lands, most of the
issues can be solved by collaborators manually, before committing.

channel projects (#8456)
Add plumbing for hosted projects. This will currently show them if they
exist
but provides no UX to create/rename/delete them.

Also changed the `ChannelId` type to not auto-cast to u64; this avoids
type
confusion if you have multiple id types.

Rework loading images from files (#7088)
This PR is a follow-up to #7084, where I noted that I wasn't satisfied
with using `SharedUri` to represent both URIs and paths on the local
filesystem:

> I'm still not entirely happy with this naming, as the file paths that
we can store in here are not _really_ URIs, as they are lacking a
protocol.
>
> I want to explore changing `SharedUri` / `SharedUrl` back to alway
storing a URL and treat local filepaths differently, as it seems we're
conflating two different concerns under the same umbrella, at the
moment.

`SharedUri` has now been reverted to just containing a `SharedString`
with a URI.

`ImageSource` now has a new `File` variant that is used to load an image
from a `PathBuf`.

Rename SharedUrl to SharedUri (#7084)
This PR renames `SharedUrl` to `SharedUri` to better reflect its intent.

I'm still not entirely happy with this naming, as the file paths that we
can store in here are not _really_ URIs, as they are lacking a protocol.

I want to explore changing `SharedUri` / `SharedUrl` back to alway
storing a URL and treat local filepaths differently, as it seems we're
conflating two different concerns under the same umbrella, at the
moment.

gpui: Support loading image from filesystem (#6978)
This PR implements support for loading and displaying images from a
local file using gpui's `img` element.

API Changes:
- Changed `SharedUrl` to `SharedUrl::File`, `SharedUrl::Network`

Usage:
```rust
// load from network
img(SharedUrl::network(...)) // previously img(SharedUrl(...)

// load from filesystem
img(SharedUrl::file(...))
```

This will be useful when implementing markdown image support, because we
need to be able to render images from the filesystem (relative/absolute
path), e.g. when implementing markdown preview #5064.

I also added an example `image` to the gpui crate, let me know if this
is useful. Showcase:
<img width="872" alt="image"
src="https://github.com/zed-industries/zed/assets/53836821/b4310a26-db81-44fa-9a7b-61e7d0ad4349">

**Note**: The example is fetching images from [Lorem
Picsum](https://picsum.photos) ([Github
Repo](https://github.com/DMarby/picsum-photos)), which is a free
resource for fetching images in a specific size. Please let me know if
you're okay with using this in the example.
