AgentWorkflows v0.4.0

Docs: https://ramazankara.github.io/agentworkflows/

• Add the TypeScript workflow SDK with governed model and tool activities, human approval,
  and PR review and support triage examples that run against the local fakes.
• Make the console easier to read: friendly workflow names, distinct run IDs, one grouped
  card for notification receipts, a summary for published or rejected results, and a
  Rejected badge in the run list. Run lists now include each completed run's outcome.
• Explain provider fallback on the run page, including the conservative hold kept for a
  failed attempt that reported no usage, and note it on the Costs page.
• Show run lists, triggers, costs and providers as stacked cards on phones, with a compact
  single-row navigation.
• Return a realistic synthetic briefing from the research fake, rename the always-failing
  demo route to demo-fallback, and align the quickstart with the real step timeline.
• Publish releases from a tag-only workflow: multi-arch images and Helm charts signed with
  Cosign, plus the Python wheel, source archive and TypeScript SDK package with checksums.
