[Media] patent: a TUI that searches 11 registries to tell you if your dev-tool idea already exists

I kept reinventing tools that already existed, so I built patent which is a prior-art search for code ideas. You give it a plain-English idea; it fans out concurrently to 11 ecosystems, ranks results by cosine similarity using local fastembed embeddings, and asks a local Ollama model for a scoped verdict (Open/Crowded/Saturated + gaps). Output is a ratatui TUI (detail view, sort, filter, mouse) or --json.

Rust-specific notes: clean lib/bin split (testable core + thin CLI/TUI shell), every source is best-effort (one failing never fails the run, "not reached" is surfaced), and the integrity rule "can prove something exists, never that it doesn't" is enforced in verdict.rs (it floors the saturation level against the embeddings and scrubs any absence-claiming copy), not just trusted to the prompt.
