Conversation
Adds an opt-in workflow that fires repository_dispatch on release events
to a downstream repository, when one is configured via the
RELEASE_AUTOMATION_REPO repository variable. When the variable is unset,
the workflow is a no-op so forks and other adopters pay no overhead.
Two event types are emitted:
mcp-server-release-drafted on release: { types: [created] }
mcp-server-released on release: { types: [published] }
Prereleases are skipped for both event types. The downstream payload is
{ tag, url } only — no other release data crosses the boundary.
Required when RELEASE_AUTOMATION_REPO is set:
Variable RELEASE_AUTOMATION_REPO owner/repo of the downstream
Secret RELEASE_AUTOMATION_DISPATCH_PAT PAT with actions:write on it

Why this exists
Allows release events from this repository to drive downstream automation (e.g. dependency bumps, downstream test runs, notifications) without coupling that automation's logic into this repository. The downstream repository owns its own behavior; this workflow just signals the event.
Testing
