}Create an annotation
Creates a manual annotation. Requires the web_analytics write permission.
source is always stored as manual and source_id is always empty: only the platform writes automatic rows, so there is no way to attach a caller-supplied key to one. This endpoint is therefore not idempotent — a retried call (a CI job re-running a deploy marker, for instance) writes a second annotation. De-duplicate on the caller’s side, or delete the extra row.
Omitted color and timezone are filled in server-side: the default colour, and the workspace timezone falling back to UTC.
