Add an optional io/fs.FS to filepicker's model to allow to browse an abstracted filesystem instead of the full filesystem exposed by the 'os' package. Note that Go 1.25 will add io/fs.ReadLink, but we can't use it yet. So we implement symlink resolution here. By the way, references to os types and constants which are aliases to same symbols in io/fs are replaced: os.Mode*, os.DirEntry.

This requires so far my fork of bubbles/filepicker that allows to browse an io/fs.FS (see charmbracelet/bubbles#759).

Add an optional
io/fs.FStofilepicker's model to allow to browse an abstracted filesystem as an alternative to the full filesystem exposed by theospackage.The filepicker API is extended (and generalized thanks to io/fs.FS), without any breaking change.
This allows for example to browse limited a subdirectory by using
os.Root(go1.24+):Note that Go 1.25 will add
io/fs.ReadLink, but we can't use it yet. So we implement symlink resolution here.By the way, references to
ostypes and constants which are aliases to same symbols inio/fsare replaced:os.Mode*,os.DirEntry.Example
