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.
On a published GitHub release, post the notes to the ECC Discord
#announcements channel (via bot), pin it, and cross-post to GitHub
Discussions (Announcements category). Release data flows through env vars
(no shell interpolation of untrusted input). Secrets: DISCORD_BOT_TOKEN,
DISCORD_ANNOUNCE_CHANNEL_ID (repo secrets), GITHUB_TOKEN.
Ties the 2.0.0/1.11.0 official release to the community launch.
