Generated AGENTS.md links to missing static/llms.txt

scripts/agents.js と scripts/lib/docs-utils.js から始め、次に docs/AGENTS.md と docs/static/ ディレクトリを調べます。discoverTopLevelSections() が CONSTANTS.skipDirs をどのように使っているかを追跡し、生成されたインデックスが ./static/llms.txt にリンクしなくなっていることを確認します。生成された llms.txt が存在する場合を除き、アセットのみのディレクトリが除外されれば完了です。

Summary

The generated docs/AGENTS.md currently includes this entry:

- [Static](./static/llms.txt)

However, docs/static/llms.txt does not exist. The repository has a docs/static/ directory, but it appears to contain static assets rather than a documentation section with its own generated llms.txt file.

Where it seems to come from

docs/AGENTS.md is generated by scripts/agents.js, which calls discoverTopLevelSections() from scripts/lib/docs-utils.js.

discoverTopLevelSections() includes top-level directories unless they are listed in CONSTANTS.skipDirs. static is not currently in that skip list, so the generator treats docs/static/ as a docs section and emits a link to ./static/llms.txt.

Expected behavior

The generated AGENTS index should not link to ./static/llms.txt unless that file is generated/committed. If docs/static/ is only an asset directory, it should likely be skipped by the section discovery logic.

Reproduction

1. Inspect docs/AGENTS.md.
2. Find the Static entry under the LLM entry point section.
3. Check that docs/static/llms.txt is missing.

Possible fix

Add static to the docs generator skip list, or otherwise exclude asset-only directories from discoverTopLevelSections().
