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
