## Tiny patch

This is a tiny release, but we thought it would be worth it.

* Updated [Bubble Tea](https://github.com/charmbracelet/bubbletea/releases/tag/v2.0.9) with a couple fixes for some terminal emulators.
* Updated [Fantasy](https://github.com/charmbracelet/fantasy/releases/tag/v0.41.2) with fixes for AWS SSO and better cache hitting.
*  Fixed wrong background color on permissions dialog. This was a regression from adding Bash syntax highlighting on [v0.89.0](https://github.com/charmbracelet/crush/releases/tag/v0.89.0).
* Updated our `.gitattributes` to make development easier on Windows. We're normalizing LF (instead of CRLF) as line breaks to fix some tests on Windows.

## Changelog
### Fixed
* ed15da4c46e0bdc3afae4842db54e7def7b9f15e: fix(ui): use dialog background for bash syntax highlighting in permissions (#3575) (@andreynering)
### Other stuff
* 0f14334fb03703a5557f875d182e347e6375e0e7: chore: normalize line endings to `lf` via `.gitattributes` (#3555) (@Lin-BoYuan)

<summary>Verifying the artifacts</summary>

First, download the [`checksums.txt` file](https://github.com/charmbracelet/crush/releases/download/v0.90.0/checksums.txt) and the [`checksums.txt.sigstore.json` file](https://github.com/charmbracelet/crush/releases/download/v0.90.0/checksums.txt.sigstore.json) files, for example, with `wget`:

```bash
wget 'https://github.com/charmbracelet/crush/releases/download/v0.90.0/checksums.txt'
wget 'https://github.com/charmbracelet/crush/releases/download/v0.90.0/checksums.txt.sigstore.json'
```

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

```bash
cosign verify-blob \
  --certificate-identity 'https://github.com/charmbracelet/meta/.github/workflows/goreleaser.yml@refs/heads/main' \
  --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!
