Uses ripgrep's --replace feature to mark exact match positions with
separators (__snacks__${0}__snacks__), then parses these positions
for precise highlighting.
Benefits:
- Exact match highlighting in list, preview, and file formatter
- Works with any grep pattern (regex, fixed-string, case-insensitive)
- No need for pattern parsing or vim.regex workarounds
- Positions are provided directly by ripgrep, guaranteed accurate
Implementation:
- Added item.positions field to track match character indices
- New highlight.matches() helper for creating match extmarks
- Modified grep source to parse and extract positions from rg output
- Updated list, preview, and format to use positions when available

## 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
