Metaculus question metadata

Returns public metadata for one Metaculus question, including option labels, option history, scaling metadata, resolution fields, and timing fields when present.

Response behavior

- `data.public_page_derived` is `true`. - `data.options`, `data.all_options_ever`, and `data.options_history` are present for public multiple-choice questions when the page exposes them. - `data.scaling`, `data.resolution`, and `data.possibilities` are returned only when public page data exposes those fields. - Invalid ids return invalid-parameter errors before upstream IO. - Upstream authentication, challenge pages, missing question payloads, or parser drift is returned as a typed upstream error.
