Updated VaultTools to use adapters for all utility method calls:
- SearchUtils.searchWaypoints() now receives vault adapter
- WaypointUtils.isFolderNote() now receives vault adapter
- LinkUtils.validateWikilinks() now receives vault and metadata adapters
- LinkUtils.resolveLink() now receives vault and metadata adapters
- LinkUtils.getBacklinks() now receives vault and metadata adapters
Removed App dependency from VaultTools constructor - now only requires
vault and metadata adapters. Updated factory and all test files accordingly.
All tests passing (336/336).
Update VaultTools constructor to accept IVaultAdapter and
IMetadataCacheAdapter. Add factory function for production usage.
Update stat, exists, and createFileMetadataWithFrontmatter methods.
