fix(registry): sync AI plugin feeds from Codex catalog

[kantorcodes]

Summary

• seed awesome-ai-plugins feeds from the live awesome-codex-plugins JSON catalog instead of the non-parseable README
• normalize Codex ecosystem metadata and mark Registry Broker featured
• generate portable marketplace entries that do not require local plugin clones

Verification

• python3 -B -c 'import ast, pathlib; ast.parse(pathlib.Path("scripts/generate_plugins_json.py").read_text())'

Note: local HOL Guard blocked writing generated JSON artifacts. The repo workflow is expected to regenerate and push plugins.json and .agents/plugins/marketplace.json on this PR.

Code Review

This pull request enhances the plugin generation script by adding the ability to fetch plugin data from a remote upstream URL, while maintaining the local README as a fallback. It introduces several utility functions for normalizing plugin data, sorting entries with a pinned repository, and formatting marketplace entries. The review feedback suggests improving the robustness of repository and URL parsing by ensuring trailing slashes and '.git' suffixes are consistently handled during normalization and regex matching.

WARNING

File	Line	Issue
scripts/generate_plugins_json.py	73	No HTTP status code validation after urlopen() - if the upstream URL returns 404, 500, or other error, the subsequent json.loads() will fail with a confusing parsing error rather than a clear "upstream unavailable" message.

Other Observations (not in diff)

Issues found in unchanged code that cannot receive inline comments:

File	Line	Issue
scripts/generate_plugins_json.py	47	CRITICAL: The category extraction from README subcategory headers was removed (current_category = category_match.group(1) was deleted). When falling back to README parsing, plugins will be missing the category field, which is required by the plugin schema and breaks the marketplace output.
