fix(tui): avoid cwd-path matches in @ autocomplete

Only use fd --full-path for path queries so plain fuzzy @ autocomplete results no longer depend on whether the cwd path contains the query text.

closes #2778

 ### Fixed
 
+- Fixed `@` autocomplete fuzzy search to stop matching against the full base path for plain queries, so worktree or cwd paths containing the query text no longer crowd out real results such as `@plan` suggestions ([#2778](https://github.com/badlogic/pi-mono/issues/2778))
 - Fixed xterm `modifyOtherKeys` printable input so shifted uppercase letters insert correctly in the editor and shifted letter bindings parse and match consistently ([#3436](https://github.com/badlogic/pi-mono/issues/3436))
