Use a builtin: filename-based ID instead of generating a fresh UUID each time the asset list is rebuilt. This lets the existing GUID-keyed list and file-metadata map recognize the same built-in asset after reloads and download-source changes.
Extract the fix and its two JVM regression tests from local/talkback-all-10. Preserve stored asset GUIDs, matching built-in replacement, locked flags, and URL behavior. No persisted IDs, accessibility semantics, metadata formatting, or editor behavior are changed.
