v0.98.0

# Rex, OSC 7501, xAI/Grok OAuth and more

Hey! There’s some good quality of life stuff in this release. Let’s take a look!

## It’s Rex Time

Following an update on [Bubbletea](https://github.com/charmbracelet/bubbletea) Crush now supports the [Program Status Protocol](https://www.superlogical.com/rex/docs/build/program-status), aka `OSC 7501`, [created by Superlogical for Rex](https://www.superlogical.com/updates/public-testing-beginning)! As a bonus, [TUIOS](https://github.com/Gaurav-Gosain/tuios) also supports the protocol.

## x.AI OAuth

Now Crush supports Grok OAuth login. Enjoy!

## Many more fixes

A lot of fixes were introduced this version:

* Server side improvements by @meowgorithm 
* External editor swallowing empty buffer
* Models behind OAuth couldn't be used if they weren't in Catwalk
* Fixed MCP toggled misbehavior

And a lot more from @taciturnaxolotl. Read all below!

Good luck,

<summary>Verifying the artifacts</summary>

First, download the [`checksums.txt` file](https://github.com/charmbracelet/crush/releases/download/v0.98.0/checksums.txt) and the [`checksums.txt.sigstore.json` file](https://github.com/charmbracelet/crush/releases/download/v0.98.0/checksums.txt.sigstore.json) files, for example, with `wget`:

```bash
wget 'https://github.com/charmbracelet/crush/releases/download/v0.98.0/checksums.txt'
wget 'https://github.com/charmbracelet/crush/releases/download/v0.98.0/checksums.txt.sigstore.json'
```

Then, verify it using [`cosign`](https://github.com/sigstore/cosign):

```bash
cosign verify-blob \
  --certificate-identity-regexp '^https://github.com/charmbracelet/crush/\.github/workflows/(release|nightly)\.yml@' \
  --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
  --bundle 'checksums.txt.sigstore.json' \
  ./checksums.txt
```

If the output is `Verified OK`, you can safely use it to verify the checksums of other artifacts you downloaded from the release using `sha256sum`:

```bash
sha256sum --ignore-missing -c checksums.txt
```

Done! You artifacts are now verified!
