fix(ship): Step 18 marks the document-release subagent spawned — env prefix + auto-choose prompt (#2733)

The dispatch prompt now (1) frames the run as a SPAWNED subagent whose
LAST line is machine-parsed, (2) instructs prefixing the preamble's
gstack-skill-start invocation with GSTACK_SESSION_KIND=spawned on the
same command line (template bash blocks don't share exports), and
(3) resolves every AUQ gate to auto-choosing the recommended option,
conservative on no-recommendation, never destructive. The JSON contract
gains a required "decisions" array (auto-chosen gates, printed to the
ship console — never embedded in the public PR body) and a placement
clause so the skill's own doc-health summary stops competing with the
LAST-line JSON. Tripwire pins added; codex/factory goldens refreshed.

## Step 18: Documentation sync (via subagent, before PR creation)
**Dispatch /document-release as a subagent** using the Agent tool with `subagent_type: "general-purpose"`. The subagent gets a fresh context window — zero rot from the preceding 17 steps. It also runs the **full** `/document-release` workflow (with CHANGELOG clobber protection, doc exclusions, risky-change gates, named staging, race-safe PR body editing) rather than a weaker reimplementation.

The dispatch prompt marks the subagent session as spawned (`GSTACK_SESSION_KIND=spawned`) so document-release's interactive gates auto-choose their recommended options instead of prose-stopping — a prose-STOP inside the subagent breaks the parent's LAST-line JSON parse and drops the Documentation section (#2733).
**Sequencing:** This step runs AFTER Step 17 (Push) and BEFORE Step 19 (Create PR). The PR is created once from final HEAD with the `## Documentation` section baked into the initial body. No create-then-re-edit dance.

> Session marking: when the skill's Preamble has you run `gstack-skill-start`, prefix that exact command with `GSTACK_SESSION_KIND=spawned ` on the same command line (e.g. `GSTACK_SESSION_KIND=spawned "$_SS" --skill "document-release" ...`) — bash blocks run in separate shells, so an exported variable from an earlier block does NOT persist; the prefix must ride the invocation itself. The preamble will then echo `SESSION_KIND: spawned` and `SPAWNED_SESSION: true`.
>
> Decision gates: at EVERY decision point in the workflow (risky doc updates, CHANGELOG fixes and voice rewrites, narrative contradictions, TODO updates, the VERSION-bump question, doc-review apply decisions), do NOT call AskUserQuestion and do NOT stop to render a prose decision brief — auto-choose the RECOMMENDED option and continue; where the skill says "always use AskUserQuestion", that resolves to auto-choosing the recommendation in this spawned session. If no option is marked recommended, take the most conservative choice (skip/defer). Never auto-choose a destructive or irreversible option — take the conservative non-destructive choice instead. Never end your response waiting for an answer. Record each auto-chosen decision as one line in the `decisions` array of the final JSON.
