Home: add GitHub pill + subtle stats strip under hero

GitHub link joins the hero pills alongside Habr. Below the pills, a
muted single-line stats strip lists the auditable numbers from the
workspace tracker (merged OSS PRs, distinct upstream projects, essays,
pet projects) so the page leads with the breadth without leaning on
third-party stat badges that age poorly.

Numbers are currently hand-written to match the tracker state; a
follow-up can auto-render them at build time if maintenance becomes a
chore.
