The v2.14.0 service layer added a `limit` option to git_tag list mode
and split tag annotation into `message` (subject) and `annotationBody`
(body), but the tool-layer Zod schema was never extended — Zod
silently stripped `limit` from inputs and the output schema dropped
`annotationBody` on the way out, so documented features only reached
the CLI executor, not the MCP boundary. Added both fields to the tool
schema with matching unit tests.
