This PR adds some safeguards to ensure that users do not end up with
multiple active billing subscriptions.

We now do the following:

1. When initiating a checkout, we first make sure the user does not
already have an active subscription.
2. When creating subscriptions in response to Stripe events, we ensure
that we don't already have an active subscription.

Release Notes:

- SSH Remoting: made reconnect modal more robust

This PR makes it so that when we apply changes within a branch
buffer—currently just the edits buffer—we save the underlying buffer.

This also fixes an issue where new files created via edits were not
properly flushed to disk.

A user commented on this issue to let us know they couldn't reproduce,
which would keep it open for another 6 months. Best we can do is tell
them what to do if they can't repro, which is to close the issue
themselves.

This contains a bunch of smallish but nasty fixes:

- Heartbeat timer was never reset after first heartbeat
- Use same return value when stderr is closed as when stdout is closed
- Always check proxy process status since it should also be done when we
get to this point (either it died and our task stopped, or our task
stopped and we dropped the process handle and it was killed on drop)
- make error messages less wrongly-specific

This PR exposes the server address (or the nickname, if there is one) on
the title bar and in all modals that have the SSH header. The title bar
tooltip meta description still shows the original server address
(regardless of a nickname existing in this case), though.

We sadly have to change the underlying protocol once again. This will
likely be the last change to the core protocol without correctly
handling older versions. From here on out, we want to get better with
version handling. To do so, we introduce the notion of a string protocol
version to be explicit of when the underlying protocol last changed.

The change also changes the return values of prompts. For now we only
allow User messages from servers to match the current behaviour. We will
change this once #19222 lands which will allow slash commands to insert
user and assistant messages.

Release Notes:

- N/A

Release Notes:

- Improved prompt for generating context editor summaries.

This fixes the `ssh` proxy process not being notified when the proxy
process dies. Turns out that the server would have stdout/stderr/stdin
connected to the grand-parent ssh process connected to it and as long as
the server kept running (even once it was daemonized into the
background) the grand-parent ssh process wouldn't exit.

That in turn meant that the Zed client wasn't notified when the proxy
process died.

This PR changes the behavior of pressing the `Esc` key on the connection
input. Now, if you hit it, the address inserted into the input won't be
erased. Effectively, escape now only cancels the connection process
instead of doing both (clearing the input _and_ cancelling the
connection).

Closes #19181

When the keystroke was empty ("") the `ime_key` was converted from
`None` to `Some("")` when `with_simulated_ime` was called. That was
leading to not intentional behavior when an empty keystroke was combined
with `shift-up` in a keybinding `["workspace::SendKeystrokes", "shift-up
"]`.

By adding a `key.is_empty()` we make sure the `ime_key` keeps as `None`.

This was manually tested.

- Fixed empty keystroke with simulated ime

Before this change, `parse_block` was consuming events that it doesn't
handle. This was fine in its use in `parse_document`, but in its use in
`parse_list` this broke when there is an empty list item, causing it to
consume list end tags / list item starts / etc.

Release Notes:

- Fixed markdown preview rendering of empty list items.

Closes https://github.com/zed-industries/zed/issues/8534
Supersedes https://github.com/zed-industries/zed/pull/16349

Potential concerns:
* we do not follow up to the `/` when looking for `.editorconfig`, only
up to the worktree root.
Seems fine for most of the cases, and the rest should be solved
generically later, as the same issue exists for settings.json
* `fn language` in `AllLanguageSettings` is very hot, called very
frequently during rendering. We accumulate and parse all `.editorconfig`
file contents beforehand, but have to go over globs and match these
against the path given + merge the properties still.
This does not seem to be very bad, but needs more testing and
potentially some extra caching.


Release Notes:

- Added .editorconfig support

This simplifies rendering of excerpt headers and footers, and removes
the need to store a `BlockDisposition` on these boundary blocks. It's a
step toward implementing "replace blocks", which we want to use in the
assistant panel.

We've also cleaned up the way heights are specified for headers and
footers and fixed some visual asymmetries between the "expand upward"
and "expand downward" buttons.

Hi. While working on https://github.com/zed-industries/zed/pull/19230 I
noticed that some servers send a request to unregistered the
`textDocument/rename` capability. I thought it would be good to handle
that message in Zed:

```plaintext
[2024-10-18T21:25:07+02:00 WARN  project::lsp_store] unhandled capability unregistration: Unregistration { id: "biome_rename", method: "textDocument/rename" }
```

So this pull request implements that. Thanks.

Fixes a bug due to the `select!` macro tossing futures that had
partially read messages, causing us to desync our message reading with
the input stream.
