## Description
This PR builds on top of #743 to add flexible filename formatting in the
picker.
### Changes:
- **Flexible path truncation**: Added support for different truncation
strategies (`left`, `center`, `right`) instead of just a fixed number
- `left`: truncates the beginning of the path (e.g.,
`…/path/to/file.lua`)
- `center`: truncates the middle of the path (default behavior, e.g.,
`~/pro…/file.lua`)
- `right`: truncates the end of the path (e.g., `~/projects/long…`)
- **Dynamic width calculation**: The filename formatter now adapts to
available window width using a resolve function
- **Enhanced truncate utility**: Updated `M.truncate()` to support
left-side truncation
### Implementation:
The filename formatter now uses a `resolve` function that receives
context including the picker, item, current offset, and maximum
available width. This allows the formatter to make intelligent decisions
about how to display the path based on actual available space.
## Related Issue(s)
- Based on #743
- Addresses dynamic path formatting needs
## Technical Details
The implementation introduces:
1. `snacks.picker.format.ctx` - context passed to resolve functions
2. `snacks.picker.format.resolve` - callback type for dynamic formatting
3. `Snacks.picker.highlight.resolve()` - resolves flex text elements in
highlight arrays

## Description
In certain filesystems — such as bind mounts, NFS, FUSE, or other
mounted paths — uv.fs_scandir_next() may return a nil type for valid
directories. This causes the snacks.nvim explorer to treat mounted
folders as files, making them unexpandable in the UI.
This patch adds a fallback to resolve the correct type when
fs_scandir_next() returns nil. It uses uv.fs_stat() first, and falls
back to vim.fn.isdirectory() if needed.
This ensures that mounted directories are properly marked as navigable.
Code change summary:
- Inside Tree:expand, we now check t == nil
- If so, we call uv.fs_stat() to get the true type
- If fs_stat fails, we fallback to vim.fn.isdirectory
- Final dir = true logic remains intact
Impact:
- Fixes a long-standing bug in mounted directories under /mnt, FUSE,
etc.
- Only runs extra checks when needed (no performance hit for regular
files)
- No changes elsewhere — clean, isolated patch

## 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
