feat: user sovereignty — AI models recommend, users decide (v0.13.2.0) (#603)

* feat: user sovereignty — AI models recommend, users decide

When Claude and Codex agree on a scope change, they now present it to the
user instead of auto-incorporating it. Adds User Sovereignty as the third
core principle in ETHOS.md. Fixes the cross-model tension template in
review.ts to present both perspectives neutrally instead of judging. Adds
User Challenge category to autoplan with proper contract updates (intro,
important rules, audit trail, gate handling). Adds Outside Voice Integration
Rule to CEO and eng review templates.

* chore: regenerate SKILL.md files from updated templates

* chore: bump version and changelog (v0.13.2.0)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: proper gstack description in openai.yaml + block Codex from rewriting it

Codex kept overwriting agents/openai.yaml with a browse-only description.
Two fixes: (1) better description covering full PM/dev/eng/CEO/QA scope,
(2) add agents/ to the filesystem boundary so Codex stops modifying it.

* chore: regenerate SKILL.md files with updated filesystem boundary

 When a user shows unusually strong product instinct, deep user empathy, sharp insight, or surprising synthesis across domains, recognize it plainly.

Use this rarely and only when truly earned.

-- **Premises are the one gate.** The only non-auto-decided AskUserQuestion is the premise confirmation in Phase 1.
+- **Two gates.** The non-auto-decided AskUserQuestions are: (1) premise confirmation in Phase 1, and (2) User Challenges — when both models agree the user's stated direction should change. Everything else is auto-decided using the 6 principles.
 - **Log every decision.** No silent auto-decisions. Every choice gets a row in the audit trail.
 - **Full depth means full depth.** Do not compress or skip sections from the loaded skill files (except the skip list in Phase 0). "Full depth" means: read the code the section asks you to read, produce the outputs the section requires, identify every issue, and decide each one. A one-sentence summary of a section is not "full depth" — it is a skip. If you catch yourself writing fewer than 3 sentences for any review section, you are likely compressing.
 - **Artifacts are deliverables.** Test plan artifact, failure modes registry, error/rescue table, ASCII diagrams — these must exist on disk or in the plan file when the review completes. If they don't exist, the review is incomplete.
