Remove GET /api/0/organizations/{org}/issues/{issue_id}/ endpoint spec
This is a breaking change — integrations that rely on the affected behaviour will need updates before the change rolls out.
What changed
The OpenAPI spec entry for GET /api/0/organizations/{organization_id_or_slug}/issues/{issue_id}/ ("Retrieve an Issue") has been removed entirely. Clients relying on this documented endpoint definition (e.g. SDK generators, documentation, or contract tests) will lose the spec. The tail of the diff shows a new, heavily restructured response schema being added in the components section — suggesting the endpoint schema was likely relocated or rewritten, but the old path entry is gone. This is a Breaking change for any tooling or codegen pipeline that depends on the previously documented response shape (which included fields like activity, stats, userReportCount, pluginActions, etc. that do not appear in the replacement schema).
