feat(curator): add hermes curator list-archived command (#21236)

Lists the skills sitting in ~/.hermes/skills/.archive/ so users have
something to pass to `hermes curator restore`. `curator status` already
shows counts; this fills the name-discovery gap.

Archive layout is flat (`archive_skill` writes to `.archive/<skill>/`),
so the directory name IS the skill name — no frontmatter parsing
needed. Timestamped collision directories (`<skill>-<ts>`) are listed
literally; user can still pass them to `restore`.

Reshape of @EvilDrag0n's #20651, simplified: drop the frontmatter
rglob + preamble/trailer output + duplicate subcommand registration.
