v0.39.0

# Hello, UI rewrite

Hi! Today we're releasing a complete rewrite of the UI portion of the codebase.  We vastly simplified and flattened the UI code, putting into practice our current thinking on how complex [Bubble Tea](https://github.com/charmbracelet/bubbletea) applications should be architected. ✨

This means you get:

* Considerable performance improvements and a snappier UI
* A much better experience in long sessions
* The ability to contribute to the codebase easier than ever

What’s that you say? “Handsome Charm team, I need features?” Well, allow us to tell you more.

## History navigation, freakin’ finally

Yeah! Now you can press <kbd>up</kbd> and <kbd>down</kbd> to cycle through past prompts, just like in Bash, VSCode, and lots of other tools. Enjoy!

## Better session management

Sessions are great, but let’s face it: sometimes you want to wipe one of them off the face of the Earth. Other times you want to rename them because the LLM just didn't quite get the title right. Now you can.

In the session dialog:

* Rename sessions with <kbd>ctrl+r</kbd>
* Delete sessions with <kbd>ctrl+x</kbd>

## Expand and contract

That’s what my stomach does through out the day. It's also what you can now do with items in the chat.

* You can now click on code, diffs and thinking blocks to expand/collapse.
* The sessions dialog will now show the last updated time of each session.

## Other good stuff

* Better compatibility when dragging and dropping files into the chat
* Improved selecting and copying text from the chat
* You'll now see exactly what provider you're using in the sidebar, panel, and in message footers

Let us know what you think in [Slack](https://charm.land/discord) and [Discord](https://charm.land/discord) and keep an eye open for more enhancements coming soon.

Keep crushing it!

<summary>Verifying the artifacts</summary>

First, download the [`checksums.txt` file](https://github.com/charmbracelet/crush/releases/download/v0.39.0/checksums.txt) and the [`checksums.txt.sigstore.json` file](https://github.com/charmbracelet/crush/releases/download/v0.39.0/checksums.txt.sigstore.json) files, for example, with `wget`:

```bash
wget 'https://github.com/charmbracelet/crush/releases/download/v0.39.0/checksums.txt'
wget 'https://github.com/charmbracelet/crush/releases/download/v0.39.0/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!
