Add ponytail plugin marketplace (#6)

* Add ponytail plugin marketplace and PaperBanana skill reference

Wires DietrichGebert/ponytail (lazy-senior-dev YAGNI skill pack) into
the installer catalog as a new plugin-marketplace group, matching the
caveman/agent-skills pattern. Documents dwzhu-pku/PaperBanana as an
external skill source instead — it has no Claude Code plugin
marketplace and its run.py depends on the full Python framework repo
being cloned separately, so it isn't vendored into the installer.

* Drop PaperBanana references

PaperBanana isn't a Claude Code plugin or a self-contained skill, so
documenting it alongside the real ponytail integration added more
confusion than value. Keeping the PR scoped to ponytail only.
