The remaining helpers and dispatchers were uncovered: - `cj/print--resolve-spooler`: explicit-string on PATH, explicit-string missing (error), `auto` prefers lpr, `auto` falls back to lp, `auto` with nothing on PATH (error), `auto` returns cached value, invalid spooler symbol (error). - `cj/copy-buffer-name`: places the current buffer's name on the kill ring with a confirmation message. - `cj/view-buffer-in-eww`: hands the file off to `eww-open-file` when visiting a file, errors otherwise. - `cj/--email-handle-is-type-p`: prefix-matches content-types, handles nil handle without signaling. - `cj/--diff-with-regular-diff`: writes a unified diff into the target buffer with header + diff output. - `cj/diff-buffer-with-file`: errors when not visiting a file, messages "No differences" when diff -q returns 0. 16 new tests total. `call-process`, `executable-find`, `eww-open-file`, `mm-handle-type`, `diff-mode` are stubbed.
