Description: adapters/copilot, adapters/gemini, adapters/perplexity are 8-line inert stubs (createUnverifiedStub) — deliberately return no messages until verified. The repo already has a written playbook: docs/adding-a-provider.md. This is about as well-scoped as an open-source task gets.

Expected outcome: One provider's adapter goes from stub to a verified real adapter, mirroring the structure of adapters/chatgpt or adapters/claude.

Acceptance criteria:

• Selectors verified against a live conversation; verified: true set
• origin added to manifest.json host permissions/content_scripts
• a maintainer confirms injection on a live page before merge (per the adapter's own doc comment).
