…migrations Create Tag table schemas to test Kysely.
- Implement backend fetch methods. - Implement support for conjunction per criteria in search files. - Implement optional startup of the backend as a web worker. - Add a small delay before a heavy fetch in average to ensure loading animations start before the backend blocks the render thread, improving UX.
implement create and save methods and all the other interface methods.
…eries. Implements #69 - Reworked advanced search editor to edit conjunctions and nesting in groups. - Reworked saved searches panel to show and use sub-queries and sub-criteria.
…gration bugs for the backend in worker mode, and set them to always work in worker mode.
…sing for heavy database tasks. Fixes #86 This commit implements some refactors and new features aiming to enable the app to scale much better with larger gallery libraries. This should significantly reduce memory usage, improve loading times, and prevent app freezes or crashes when handling a huge amount of files. Now the app should be able to scale almost unlimitedly, the only limits being disk space and time when computing transversal operations across all records. - Implemented bidirectional cursor pagination in all the views except for missing files, now the app loads the files it needs when reaching the edges of the scroll instead of loading all the files in the view. - Implement a batch processor in an accumulator pattern to process huge sets of files, and refactor all the features that did a fetch-all to use it instead. - Implement specialized backend queries to compare added files, missing files and missing files reconciliation when manually syncing locations. - Refactored scroll positioning methods to work with the new fetching method.

…oaded in the main view fileList. - Created optimized backend methods for bulk tagging and tag removal for files filtered by criteria. - Replaced all operations on file selection with contextual methods that dispatch the operation to the current selection or to all filtered files in batches.
…axvars limit was exceeded, now upsert methods insert in batches. - Added a cached fileCount to each tag, and removed ovservable based calculations. - Implemented batch based methods to update file counts to all or any sub set of tags. - Remove the Load tag file counts at startup option.

This PR implements a backend and database migration from Dexie to SQLite3 using Better-sqlite3 and Kysely, achieving better performance and scalability in general. This also adds several enhanced features now possible thanks to this migration.
