fix(landing): redirect /privacy → /policy to unblock CWS extension publish

[Smetools]

Why

Chrome Web Store has `https://knowcap.ai/privacy\` registered as the
Knowcap extension's privacy URL, but the actual privacy policy page
lives at `/policy` (created in 988833f, never at /privacy). Google's
publish-time reachability check 404s on the URL and blocks every
extension publish with:

```
"Publish condition not met: Privacy policy link is not reachable."
```

Has silently blocked every extension publish since 1.21.6 (May 6).
1.21.19 has been sitting unpublished in the CWS dashboard for days.

Fix

Next.js permanent redirects `/privacy` and `/privacy-policy` → `/policy`
in `next.config.js`. Both URLs now return 200 (via 308), Google's
reachability check passes, and anyone googling "knowcap privacy" also
lands on the policy.

Test Plan

• After Vercel auto-deploys this merge, `curl -sSL -o /dev/null -w "%{http_code}\n" https://knowcap.ai/privacy\` returns 200.
• Re-run `gh workflow run extension-publish-debug.yml --repo Knowcap-V2/knowcap -F target=default` — the POST publish step prints HTTP 200 instead of 400.
• CWS update endpoint reports 1.21.19 within minutes:
  ```
  curl -s "https://clients2.google.com/service/update2/crx?response=updatecheck&prodversion=120.0&acceptformat=crx3&x=id%3Dmdcodkbhabjcmbajfmapfiimlkeheche%26v%3D0.0.1%26uc" | grep -oP 'version="[^"]+"'
  ```

🐰 Two paths once lost in time,
Now guide where policies align,
From /privacy to /policy bright,
A hop, a redirect, all feels right!
The rabbit hops through cleaner routes. ✨
