Bug 1: Wikilink autocomplete now always inserts the vault-relative path
as the target (e.g. [[docs/adr/0001-tauri-stack|Title]]) instead of
just the filename. This ensures wikilinks are unambiguous and resolve
correctly across subfolders after reload.
Bug 2: unique_dest_path now excludes the source file from collision
checks, preventing false positives where a note's own file is treated
as a naming conflict (causing silent -2 suffix renames).
