The `open-prose` plugin ships to two marketplaces (Claude Code and Codex) via three manifest surfaces with overlapping but drifted metadata. This change unifies copy across those surfaces behind a single declarative source, ships visual assets for the Codex `interface` block, gates drift in CI, and adds a maintainer-facing submission playbook to `RELEASE.md`.
## Changes
- **Copy sync** — `.plugin-meta.json` declares the canonical strings; `scripts/sync-copy.sh` writes them into every declared destination (mirrors `bump-version.sh`). `--check` mode asserts byte-equality and reports drift.
- **Unified manifests** — same descriptions across `.claude-plugin/`, `.codex-plugin/`, and `.agents/plugins/`. Registry name aligned to `openprose` (plugin name `open-prose` unchanged). Codex `skills` path normalized.
- **Visual assets** — `assets/plugin/logo.png` (512×512) and `assets/plugin/composer-icon.png` (64×64), wired into the Codex `interface` block with `brandColor` (`#8a6b2e`), `websiteURL`, and the icon slots.
- **CI gates** — four new steps in `.github/workflows/plugin-manifest.yml` covering copy sync, asset presence, Codex interface completeness, and unified registry names. Existing version-sync gate untouched.
- **Submission playbook** — new `## Marketplace submission` section in `RELEASE.md` covering Claude Code (live today) and the Codex Plugin Directory (curated; self-serve coming soon).
Index run scaffolded new READMEs for all subdirectories. Review run
added the missing profiler.prose entry to skills/open-prose/lib/README.md
(cost, token usage, and time profiling for completed runs).
