feat(edgeparse): add EdgeParse plugin to marketplace

[amondnet]

Summary

• Add EdgeParse as a built-in plugin providing Rust-native PDF extraction (Markdown/JSON/HTML/text output)
• Register EdgeParse in .claude-plugin/marketplace.json and release-please-config.json
• Add EdgeParse to the Built-in Plugins section in README.md
• Update MarkItDown skill to recommend EdgeParse for PDF extraction use cases

Test plan

• Verify plugins/edgeparse/.claude-plugin/plugin.json is valid (claude plugin validate plugins/edgeparse)
• Confirm EdgeParse entry appears correctly in .claude-plugin/marketplace.json
• Confirm MarkItDown skill routes PDF tasks to EdgeParse

Summary by cubic

Add edgeparse as a built-in plugin for fast, deterministic PDF extraction to Markdown/JSON/HTML/text. Improves PDF workflows by surfacing the plugin in the marketplace/docs and guiding users to use it for PDFs.

• New Features
  • Added plugins/edgeparse skill with API and integration docs, plugin manifest, and skills lock.
  • Registered edgeparse in .claude-plugin/marketplace.json and set up releases in release-please-config.json.
  • Updated README Built-in Plugins with install instructions; MarkItDown skill now recommends edgeparse for PDF tasks (page ranges, borderless tables, structured output).

^{Written for commit 50f8502. Summary will update on new commits.}

Code Review

This pull request introduces the edgeparse plugin for deterministic PDF extraction, including marketplace registration, comprehensive documentation, and integration patterns. The author field in plugin.json should be updated to credit the project organization rather than an individual contributor. Additionally, the inclusion of files within the .agents/skills/ directory violates repository policy for externally managed skills; since skills-lock.json is present, these files should be managed in the upstream repository and removed from this pull request.
