List pipeline templates

Ready-made pipelines that create_pipeline can copy with templateId, so you do not have to draw a graph node by node. Each entry lists its entry nodes, the ids to key run_pipeline inputs by, and estimatedChargeUsd, what one run charges the balance as the template stands, to compare against get_credit_balance before you pick one. Clipping a long recording, file, or direct video URL into a captioned vertical clip is "video-clip-factory" (entry node "source", a File node that takes a URL); "podcast-clip-factory" pulls the newest episode from a podcast RSS feed; "campaign-clip" is for Vyro / Whop clipping briefs.
