Graduate 2.0.0-rc.1 to stable. Bump version across package, plugin,
marketplace, OpenCode, agent metadata, VERSION, and all localized docs.
Add 2.0.0 release notes + README sections (en/zh/pt-BR/tr), CHANGELOG
entry, and the ECC community Discord bot (dependency-free gateway client
+ guild command registrar). Update copilot-support and release-surface
tests for the sponsored-review migration and the 2.0.0 surface.
Refresh the active 2.0 release surface for the affaan-m/ECC repo identity, update package/plugin/workflow launch metadata, and add an operator command center for release video, partner, sponsor, consulting, and social launch execution.
