docs: refresh Markdown compatibility and measurements

[tannerlinsley]

Refresh the Markdown docs for v0.0.14. Correct the React and Octane bundle measurements and CommonMark compatibility count, document the improved list, reference, table, and code-span behavior, and link repository reports directly to GitHub so they work on tanstack.com.

Validation: all 27 documentation pages and public exports verified, build passed, and all 78 targeted compatibility tests passed.
