[codex] Fix npm publish dry run

[jonastemplestein]

Summary

• Ignore local .superset/ metadata so oxfmt --check does not fail on generated worktree config.
• Bump captun to 0.0.2 because 0.0.1 is already published on npm.

Impact

This lets the existing publish gate complete and allows the next npm publish to target a version that npm will accept.

Validation

• pnpm run check
• pnpm run test
• pnpm publish --dry-run --no-git-checks

---

Note

Low Risk
Low risk: only updates repo ignore rules and bumps the npm package version, with no runtime or API behavior changes.

Overview
Fixes publish/check workflows by adding .superset/ to .gitignore so generated metadata doesn’t break formatting checks.

Bumps the captun package version from 0.0.1 to 0.0.2 to allow the next npm publish.
