Bump all version carriers (plugin.json, package.json, README badge,
SKILL.md frontmatter) and record the release in the changelog.
Also backfills the missing [0.2.0] changelog section: that release shipped
without one, which would have left the changelog jumping 0.1.0 -> 0.2.1.
Content reconstructed from the v0.2.0 commit, not from its subject line.
