citable 0.3.0: weekly watch and prompt tracking

GitHub Action (uses: genzagents/citable@v0.3.0): the weekly watch keeps one issue per site up to date and comments (GitHub emails you) when an AI answer bot is blocked, llms.txt disappears, the site goes down or the score drops. New: a prompts: input runs prompt tracking: does ChatGPT, Claude or Perplexity cite your site for the questions that matter, and who gets cited instead; bring your own API keys. CLI: citable track. Zero dependencies. Replaces 0.2.0, whose action.yml had a YAML error.
