#225 - Serve benchmarks overview at /benchmarks/

[RamyaGuru]

Closes #225
Rename docs/benchmarks/benchmarks.md to index.md so the overview page is served at benchmarks/ instead of benchmarks/benchmarks/. Update the mkdocs nav, cross-doc links, published README URLs, footer link, and the AGENTS.md doc-path reference accordingly.

Greptile Summary

Renames docs/benchmarks/benchmarks.md to docs/benchmarks/index.md so MkDocs serves the overview at /benchmarks/ instead of the redundant /benchmarks/benchmarks/. All downstream references are updated consistently.

• mkdocs.yml nav, docs/landing/footer.html, and every relative cross-link in docs/ are updated to point at index.md.
• Published GitHub Pages URLs in README.md and the doc-path entry in AGENTS.md are corrected to drop the extra path segment.
• A repo-wide search finds no remaining references to the old benchmarks/benchmarks path.

Confidence Score: 5/5

Pure documentation rename with no code changes; all cross-references and external URLs have been updated and no stale links remain.

The change is a single file rename accompanied by exhaustive reference updates across every file that linked to the old path. The commit carries a valid DCO sign-off and follows the required # - <title> format. No logic, build system, or API surface is touched.

No files require special attention.
