v0.3.0

Corrects an install command that never existed, propagated into the release-workflow skill and the repo-conventions-scout agent and from there into the repos this plugin documents. release-workflow also gains the marketplace repin step, without which a tagged release reaches nobody.

Changed

• Docs: README.md — the version badge reads the latest GitHub release instead of a hardcoded 0.2.0, so it cannot fall behind a tag. Verified it renders v0.2.0 today.
• Docs: docs/versioning.md — release steps now include cutting the GitHub release (step 6), which the repo has always done but never documented; the marketplace repin follows as step 7. Matches the org rule in the catalog's own versioning doc: every tag carries a release titled exactly the tag name, with the CHANGELOG section as the body.
• Docs: docs/install.md — the marketplace command uses the canonical Cadasto casing, matching README.md; the two disagreed in the same command.
• Docs: sentence-case H1s in docs/testing.md, docs/versioning.md, docs/skill-authoring.md; "for example" over "e.g."; docs/testing.md opens with its subject rather than "There is".
• Skills: release-workflow — new Step 6 and checklist item: repin the entry in Cadasto/plugin-marketplace for both plugin repos. The catalog pins each entry to a release tag, so pushing the tag no longer ships the release.
• Docs: docs/versioning.md — the marketplace no longer tracks main; added as a release step.

Fixed

• Docs: README.md — the table of contents omitted the Documentation section, so the four docs/ references were unreachable from the contents list.
• Docs: claude plugin add is not a Claude Code command. README.md, docs/install.md, CONTRIBUTING.md, and AGENTS.md load a local working copy with claude --plugin-dir <path>, which applies to that session only; the README's Claude Code install now shows the marketplace flow.
• Skills, Agents: release-workflow and repo-conventions-scout carried the same non-existent command and propagated it into the repos they document.
