## Description
From the docs on `:help vim.ui.select`
```
• {on_choice} (`fun(item: any?, idx: integer?)`) Called once the user
made a choice. `idx` is the 1-based index of `item`
within `items`. `nil` if the user aborted the dialog.
```
Right now the behavior will call `on_choice` if the user confirmed a
selection, but will not be called at all if the user explicitly or
implicitly closes the picker. As a plugin author, I rely on the
guarantee that if I call `vim.ui.select`, the callback _will_ be called
either with a value or with a nil.
I just added the simplest, dumbest possible fix for this that prevents
double-calling the callback.

## Description
More info coming tomorrow.
In short:
- very fast. pretty much realtime filtering/sorting in huge repos (like
1.7 million files)
- extensible
- easy to customize the layout (and lots of presets) with
`snacks.layout`
- simple to create custom pickers
- `vim.ui.select`
- lots of builtin pickers
- uses treesitter highlighting wherever it makes sense
- fast lua fuzzy matcher which supports the [fzf
syntax](https://junegunn.github.io/fzf/search-syntax/) and additionally
supports field filters, like `file:lua$ 'function`
There's no snacks picker command, just use lua.
```lua
-- all pickers
Snacks.picker()
-- run files picker
Snacks.picker.files(opts)
Snacks.picker.pick("files", opts)
Snacks.picker.pick({source = "files", ...})
```

## Todo
- [x] issue with preview loc not always correct when scrolling fast in
list (probably due to `snacks.scroll`)
- [x] `grep` (`live_grep`) is sometimes too fast in large repos and can
impact ui rendering. Not very noticeable, but something I want to look
at.
- [x] docs
- [x] treesitter highlights are broken. Messed something up somewhere
