*	fix(dirvish): guard nil file and reject path-traversal playlist names	Craig Jennings	14 days	1	-0/+15
\| \| \| \| \| \|	cj/set-wallpaper passed `(dired-file-name-at-point)` straight to `expand-file-name`, so running it with no file at point raised a bare `wrong-type-argument` instead of a clear error. cj/dired-create-playlist-from-marked expanded the raw playlist name under `music-dir` without checking it, so a name like "../foo" or "/etc/foo" would write outside the music directory. I added a nil-file guard to set-wallpaper and a `cj/--playlist-name-safe-p` check that rejects any name carrying a directory separator before the path is built. Both paths now fail cleanly with a user-error. Regression tests went into the existing wrapper and playlist test files.
*	refactor(dirvish): extract playlist filter and sanitize helpers	Craig Jennings	2026-05-10	1	-0/+82
	`cj/dired-create-playlist-from-marked' had its audio-file filtering and trailing-`.m3u' stripping inline among the dired marking, prompting, overwrite-loop, and file-write logic. Lift each into its own pure helper: - `cj/--playlist-filter-audio (files extensions)' returns only files whose extension matches one of EXTENSIONS (lowercase, no dot). Case-insensitive on the file side. - `cj/--playlist-sanitize-name (name)' strips a trailing `.m3u' suffix; embedded `.m3u' that isn't at the end is preserved. Ten Normal/Boundary tests cover keep-only-audio, case-insensitivity, files-without-extension excluded, empty inputs, and the sanitize edge cases (bare name, embedded `.m3u', empty string, just `.m3u').
