Sync Tokens

WebDAV sync lets clients ask for changes since a previous token instead of refetching an entire collection.

Laravel DAV records collection mutations and advances the collection sync token when resources are created, updated, or deleted.

The package emits Bambamboole\LaravelDav\Events\DavCollectionChanged for collection mutations. The event includes:

Property	Description
$ownerId	Owner identifier.
$type	calendar or addressbook.
$collectionId	Collection primary key.
$resourceUri	Affected object URI, or null for collection-level changes.
$operation	created, updated, or deleted.
$syncToken	New collection sync token.

Clients use these tokens through RFC 6578 sync reports.
