chore: add the version check, ligature and search entries to 0.11.4

Fixed gains the version check that reported whatever it was running as the
newest release whenever it could not reach the listing, and logged nothing
about it, which is placed high because an administrator reads it as an answer
rather than a failure. It also gains the arrow sequences drawn as glyphs, which
had text look altered although every character was stored and sent as typed;
that one sits with the other reading corrections.

Added gains the text search moved off the path the server answers on, so a long
search no longer keeps other requests waiting.

The metadata entry gains the four vector stores that never applied the shared
size cap, coercion and sanitising, bringing them in line with the other eleven
rather than standing as an entry of its own.

 ### Added
 
-- 🏷️ **Custom file metadata.** Metadata attached to an uploaded file now travels with the pieces that file is split into and arrives with the retrieved sources, the oversized and internal fields left out.

 - 🛡️ **Security Advisory**: This release includes security and access-control fixes. We recommend updating production deployments at your earliest convenience. Not all security fixes in this version may be enumerated in the fixed section. Some may be withheld for a short time to give administrators time to upgrade.
