Refactored picker resume functionality to support multiple picker states instead of just the last one. Each picker source now maintains its own resume state, allowing users to resume any previously opened picker.
Key improvements:
- Multi-state storage: Each picker source tracks its own state independently
- Flexible API: `Snacks.picker.resume({ source = "files" })` or with include/exclude options
- LSP caching: Cache LSP results for instant resume of LSP pickers
- Better UX: Can resume specific pickers by source name
Moved resume logic to dedicated `picker/resume.lua` module for better separation of concerns.

## 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
