P4: Production onboarding, marketplace readiness, and public documentation

[iamfatness]

Problem

A published app must be understandable to external users without exposing internal credential setup or overpromising Sidecar capabilities.

Outcomes

• Docs match current product UI and capabilities.
• Marketplace/OAuth/Public Client setup is documented for publisher operations, not end-user setup.
• Website, README, release notes, installer, and screenshots stay synchronized.

Acceptance criteria

• Fresh user can install, sign in, join, assign sources, record ISO, and collect diagnostics from docs alone.
• Sidecar docs are gated until Sidecar is production-ready.
• Website deployment is part of release checklist.

Progress in commit 68fe17b: README Output Profiles section now documents that profiles preserve assignment mode, requested resolution, channel mode, and audio role.

[iamfatness]

Progress update: updated docs/index.html and regenerated public/ so GitHub docs and corevideo.iamfatness.us content include the new Output Manager audio-role/share/spotlight wording and the OSC Active Speaker Director commands/replies. The deploy-site workflow should publish this on main.

[iamfatness]

Deploy status: docs changes are pushed and site build succeeds locally, but the deploy-site workflow is failing before Wrangler because GitHub secret CLOUDFLARE_ACCOUNT_ID is blank. CLOUDFLARE_API_TOKEN is present. Add CLOUDFLARE_ACCOUNT_ID in repo secrets (or move the non-secret account id into workflow/env config) and rerun Deploy Site to publish corevideo.iamfatness.us.

Added production onboarding docs in cbd6a99.

What changed:

• Added docs/OPERATOR_QUICKSTART.md for end-user install/sign-in/join/output assignment/active speaker/ISO/diagnostics workflows.
• Added docs/RELEASE_CHECKLIST.md for publisher validation before shipping GitHub releases and installers.
• Linked the quickstart from README.
• Linked the quickstart/checklist from the published docs HTML installation section.

Scope notes:

• The operator guide explicitly treats the OBS plugin as the production surface today and gates Sidecar as roadmap until the Sidecar issues are complete.
• The quickstart states that published installers include the Zoom SDK/runtime and should not ask end users for Zoom app credentials.

Validation:

• git diff --check
