* feat(command-palette): add projects to existing fuzzy search
Adds projects to the existing command palette search — same single-input
fuzzy search that already covers sessions, files, settings, and commands.
Projects are scored alongside everything else by scoreByFuzzyQuery, and
the best-matching result appears first regardless of type.
Selecting a project opens a new session draft with the project pre-selected.
Closes#976
* fix(command-palette): keep file search tied to debounced query
