Fork card: depends are the stored question's prose lines, verbatim

`huginn schema question` types depends as up to 8 Lines, not references;
Huginn PR #29 (desk.rs:87) hashes them as stored. The page said each was a
campaign:kind:label rendering of a reference. Hash vectors are unchanged
(their depends strings are ids written as text).

+- **Hashed (the shown members):** `title`, `context`, `options` (each `{id, text}`, in shown order), `recommendation` (an option id, **never nil**: the stored `question` requires `recommended`), `depends` (strings, each one of the stored question's `depends` lines verbatim, at most 8, in shown order, empty when none; the stored kind holds prose lines, so a line may read like a reference such as `campaign:kind:label` but is hashed as the text it is).
 - **Not hashed:** `fork_id` (bound beside the hash), `leans` (an option id or nil), `flag`, `raised_in`, `deciders`, `status` (`open` or `closed`), `ruling` (the ruling id when a ruling closed the fork; nil when the card is open, and nil on a closed card whose question was withdrawn or otherwise resolved with no ruling), `ruled_from` (answer ids a ruling has been admitted from; non-empty only on a closed card), `order`, and `options_hash` itself.
 - **`deciders` is read-only data.** The list is set outside the Mind, through Bifrost's admin path; the Mind reads it and the card projection copies it. A question's own `audience` may only narrow it. A Mind never writes it, so a Mind cannot add itself and answer its own fork.
 - Rules a schema cannot say, each with a negative vector: option ids are unique; `recommendation` and `leans` name an option; deciders are unique; an open card names no `ruling` and its `ruled_from` is empty (a ruling that answers a fork closes it); `ruled_from` is non-empty only when `ruling` is set; a closed card may name no ruling (the question was withdrawn, superseded or deferred: step 6 reads `status`, not the ruling); `options_hash` equals the hash of the shown members.
