This PR improves our Stripe event handling by keeping track of the last
event we've seen for each record.

The `billing_customers` and `billing_subscriptions` tables both have a
new `last_stripe_event_id` column. When we apply an event to one of
these records, we store the event ID that was applied.

Then, when we are going through events we can ignore any event that has
an ID that came before the `last_stripe_event_id` (based on the
lexicographical ordering of the IDs).

This PR makes it easier to specify custom models for the Google, OpenAI,
and Anthropic provider:

Before (google):

```json
{
  "language_models": {
    "google": {
      "available_models": [
        {
          "custom": {
            "name": "my-custom-google-model",
            "max_tokens": 12345
          }
        }
      ]
    }
  }
}
```

After (google):

```json
{
  "language_models": {
    "google": {
      "available_models": [
        {
          "name": "my-custom-google-model",
          "max_tokens": 12345
        }
      ]
    }
  }
}
```

Before (anthropic):

```json
{
  "language_models": {
    "anthropic": {
      "available_models": [
        {
          "custom": {
            "name": "my-custom-anthropic-model",
            "max_tokens": 12345
          }
        }
      ]
    }
  }
}
```

After (anthropic):

```json
{
  "language_models": {
    "anthropic": {
      "version": "1",
      "available_models": [
        {
          "name": "my-custom-anthropic-model",
          "max_tokens": 12345
        }
      ]
    }
  }
}

```

The settings will be auto-upgraded so the old versions will continue to
work (except for Google since that one has not been released).

This simplifies `PathWithPosition` by making the common use case
concrete and removing the manual, incomplete Windows path parsing.
Windows paths also don't get '/'s replaced by '\\'s anymore to limit the
responsibility of the code to just parsing out the suffix and creating
`PathBuf` from the rest. `Path::file_name()` is now used to extract the
filename and potential suffix instead of manual parsing from the full
input. This way e.g. Windows paths that begin with a drive letter are
handled correctly without platform-specific hacks.

Previously, the following lead to a bug:

1. Set OpenAI key
2. Switch to Anthropic
3. Restart Zed
4. Switch provider to OpenAI -> get prompted for authentication prompt

With this change, you won't get prompted for the OpenAI key again.

Additionally, I've generalized the implementation of tab switcher so
that - instead of explicitly listing panels it supports (at the time of
writing it was just the terminal panel and nothing else), it now relies
on Panel::pane trait method. As long as that's implemented, you get a
tab switcher support for free.

Release Notes:

- Added support for tab switcher in Assistant panel.

This adds the optional `PRESERVED_KEYS` constant to the `Settings`
trait,
which allows users of the trait to specify which keys should be written
to
the settings file, even if their current value matches the default
value.

That's useful for tagged settings that have, for example, a `"version"`
field
that should always be present in the user settings file, so we can then
reparse
the user settings based on the version.

# Summary

This commit implements Github Copilot Chat support within the existing
Assistant panel/framework. It required a little bit of trickery and
internal API modification, as Copilot doesn't use the same
authentication-style as all of the existing providers, opting to use
OAuth and a short lived API key instead of a straight API key. All
existing Assistant features should work.

Release Notes:
- Added Github Copilot Chat support
([#4673](https://github.com/zed-industries/zed/issues/4673)).

This PR lays the initial groundwork for using the Stripe events API to
reconcile the data in our system with what's in Stripe.

We're using the events API over webhooks so that we don't need to stand
up the associated infrastructure needed to handle webhooks effectively
(namely an asynchronous job queue).

Since we haven't configured the Stripe API keys yet, we won't actually
spawn the reconciliation background task yet, so this is currently a
no-op.

This PR adds a new `billing_customers` table to hold the billing
customers.

Previously we were storing both the `stripe_customer_id` and
`stripe_subscription_id` in the `billable_subscriptions` table. However,
this creates problems when we need to correlate subscription events back
to the subscription record, as we don't know the user that the Stripe
event corresponds to.

By moving the `stripe_customer_id` to a separate table we can create the
Stripe customer earlier in the flow—before we create the Stripe Checkout
session—and associate that customer with a user. This way when we
receive events down the line we can use the Stripe customer ID to
correlate it back to the user.

We're doing some destructive actions to the `billing_subscriptions`
table, but this is fine, as we haven't started using them yet.

Release Notes:

- N/A

This PR adds a new `POST /billing/subscriptions/manage` endpoint that
can be used to manage a billing subscription.

The endpoint accepts a `github_user_id` to identify the user, as well as
an optional `subscription_id` for managing a specific subscription. If
`subscription_id` is not provided, it try and use the active
subscription, if there is only one.

Right now the endpoint only supports cancelling an active subscription.
This is done by passing `"intent": "cancel"` in the request body.

The endpoint will return the URL to a Stripe customer portal session,
which the caller can redirect the user to.

Here's an example of how to call it:

```sh
curl -X POST "http://localhost:8080/billing/subscriptions/manage" \
     -H "Authorization: <ADMIN_TOKEN>" \
     -H "Content-Type: application/json" \
     -d '{"github_user_id": 12345, "intent": "cancel"}'
```

This PR adds a new `POST /billing/subscriptions` endpoint that can be
used to initiate a billing subscription.

The endpoint will use the provided `github_user_id` to look up a user,
generate a Stripe Checkout session, and then return the URL.

The caller would then redirect the user to the URL to initiate the
checkout flow.

Here's an example of how to call it:

```sh
curl -X POST "http://localhost:8080/billing/subscriptions" \
     -H "Authorization: <ADMIN_TOKEN>" \
     -H "Content-Type: application/json" \
     -d '{"github_user_id": 12345}'

- Fixed a bug that caused the inline assistant to be displayed twice in
certain circumstances.

This PR adds a new `billing_subscriptions` table to the database, as
well as some accompanying models/queries.

In this table we store a minimal amount of data from Stripe:

- The Stripe customer ID
- The Stripe subscription ID
- The status of the Stripe subscription

This should be enough for interactions with the Stripe API (e.g., to
[create a customer portal
session](https://docs.stripe.com/api/customer_portal/sessions/create)),
as well as determine whether a subscription is active (based on the
`status`).

Fixes #15426.

The `./` was implicitly assumed to be there by the prompt, so we'd end
up with `././foobar` when typing in an explicit `./`.

This fixes the issue by stripping `./` from the query, like we also
strip `/`.

Release Notes:

- Fixed paths starting with `./` breaking the new-path file picker when
the system prompts are disabled.
([#15426](https://github.com/zed-industries/zed/issues/15426)).

Release Notes:

- Improved restoring of windows across restarts: the order of the
windows is now also restored. That means windows that were in the
foreground when Zed was quit will be in the foreground after restart.
(Right now only supported on Linux/X11, not on Linux/Wayland.)

This also rolls back the `TerminalWorkDir` abstraction I added for the
original remoting, and tidies up the terminal creation code to be clear
about whether we're creating a task *or* a terminal. The previous logic
was a little muddy because it assumed we could be doing both at the same
time (which was not true).

Release Notes:

- remoting alpha: Removed the ability to specify `gh cs ssh` or `gcloud
compute ssh` etc. See https://zed.dev/docs/remote-development for
alternatives.
- remoting alpha: Added support for terminal and tasks to new
experimental ssh remoting

Vim digraphs are a way to insert special characters using sequences of
two ASCII characters. I've implemented the feature using a new `Digraph`
operator, following the example of `AddSurrounds`. There are still a few
issues that I'm not sure what the best way to resolve them is.

- To insert `ş`, the user must pause between pressing `ctrl-k` and `s
,`, otherwise it triggers the binding for `ctrl-k s`. Is there a way to
disable `ctrl-k *` bindings while in insert, replace or waiting mode?
- Is there a better way to insert a string at all of the cursors? At the
moment I'm constructing the edits manually.
- The table of default digraphs is a 1.4k line rust expression. Is this
okay as long as it's in its own module?
- I'd like a second opinion on how best to structure the settings.json
entry.
- I have omitted the "meta character" feature as I don't think it makes
sense when editing UTF-8 text.

Release Notes:

- Added support for Vim digraphs.

This PR adds another row to the LSP log view: Server traces

![image](https://github.com/user-attachments/assets/e3f77944-45e0-4d04-92fd-aea212859e86)


[Traces](https://docs.rs/lsp-types/latest/lsp_types/notification/enum.LogTrace.html)
are intended for logging execution diagnostics, which is different from
`LogMessage` that we currently support.
When `Server trace` is selected, user can select the level of tracing
(`off`/`messages`/`verbose`) to their liking.

Release Notes:

- Added support for language server tracing to the LSP log view.

Updated runtimelib to 0.14 and passed a kernel session ID through to

In this pull request, we change the zed.dev protocol so that we pass the
raw JSON for the specified provider directly to our server. This avoids
the need to define a protobuf message that's a superset of all these
formats.

@bennetbo: We also changed the settings for available_models under
zed.dev to be a flat format, because the nesting seemed too confusing.
Can you help us upgrade the local provider configuration to be
consistent with this? We do whatever we need to do when parsing the
settings to make this simple for users, even if it's a bit more complex
on our end. We want to use versioning to avoid breaking existing users,
but need to keep making progress.

```json
"zed.dev": {
  "available_models": [
    {
      "provider": "anthropic",
        "name": "some-newly-released-model-we-havent-added",
        "max_tokens": 200000
