Contract for resolved issues and issue ↔ merge request history.
ISSUE_STATE_RESOLVED: a merge with a closing reference ("Fixes #N") resolves the issue; CLOSED means closed without a fix. ResolveIssue (issue:write) resolves by hand; ReopenIssue works from closed or resolved.
IssueEvent / IssueEventKind (referenced, closed, reopened, resolved): append-only history in GetIssueResponse.events.
GetMergeRequestResponse.issues (MergeRequestIssue, MergeRequestIssueState) and issue_events. The new types live in merge_request.proto because issue.proto already imports it (no import cycle, no moved types).
