#128 site: add Q&A link to main nav and footer across all pages

[Anonymous]

Summary

Follow-up to #126. The qa-glossary PR scoped the in-nav link to the homepage only as a deliberate first wave; this PR completes the rollout to all 126 pages that carry the standard nav and footer.

• Top nav (123 pages): inserts `Q&A` between the Insights and Roadmap links.
• Footer Learn column (113 standard + 10 styled): inserts `
• Q&A and Glossary
` between Insights and Standards. The styled-variant pages (homepage, founder/contact/about, for/ buyer pages) carry the matching inline `style` attr for visual consistency.
• Bonus: the script also touched `site/_snippets/nav.html` and `site/_snippets/footer.html`, so any future page generation that pulls from those snippets will inherit the Q&A link automatically.

Idempotency

Insertions are guarded: every page that already contained a `qa-glossary` link was skipped. Verified post-rollout that no page double-inserts. The script ran cleanly with 110 skips on nav and 110 on footer (homepage already had nav; qa-glossary page already had both; pages without the standard pattern were untouched).

Spot-checks

• Homepage: nav line 1014, footer line 1658 — both present.
• Concept page (`/concepts/governance-before-generation/`): nav line 333, footer line 716 — both present.
• Buyer page (`/for/cto/`): nav line 297, footer line 492 — both present.
• `scripts/check_sticky_nav.py` passes — no regression to the CI gate added in [#127].

Files

126 `site/*/.html` modified, +246 / -0 lines (2 lines per page on average: one nav, one footer).

Test plan

• [ ] After deploy completes, load any concept/insight/use-case/integration page on mnemehq.com and confirm the Q&A link appears in both the top nav (between Insights and Roadmap) and the footer Learn column (between Insights and Standards).
• [ ] Mobile viewport ≤ 900px: confirm the Q&A link shows in the hamburger menu.
• [ ] Confirm no double-insertion or visual oddity on the homepage / buyer pages where the styled footer variant applies.
