fix(seo): make the bare DoctorDerek.com domain canonical

[DoctorDerek]

Summary

Make https://doctorderek.com/ the canonical production origin using the existing URL owners. This is a six-file hostname-only change, split into three atomic commits.

• Update root metadataBase; the existing relative canonical and Open Graph URLs resolve through it.
• Update this site's own portfolio live link and its existing regression assertions.
• Point the existing Production Lighthouse caller and README links/badge at the bare domain.

Closes #225

Vercel routing and release boundary

Read-only Vercel CLI 60.0.1 inspection under doctordereks-projects/doctor-derek confirmed the existing configuration already matches the requested behavior:

• doctorderek.com: verified, no redirect, no branch/custom-environment binding.
• www.doctorderek.com: verified, HTTP 308 redirect to doctorderek.com.
• Existing doctor-derek.vercel.app alias unchanged.

Live HTTPS checks confirmed the bare homepage returns 200; WWW returns one 308 followed by 200. Manifest and favicon paths and their query parameters survive unchanged, including an encoded space. No redirect loop. No Vercel settings, DNS, subscriptions, or secrets were changed.

The current published metadata still uses WWW. The new built metadata is bare-domain, but publishing it requires the owner's merge and normal production deployment. Recheck the live canonical/Open Graph values after that release before calling the migration complete.

Verification

• Node 24.18.0, pnpm 11.9.0, Next.js 16.3.1.
• Focused Vitest: 2 files, 19 tests passed.
• Next route type generation and strict TypeScript passed.
• Full Vitest: 41 files, 182 tests passed; configured statements, branches, functions, and lines coverage all 100%.
• Local production build passed. No secret was loaded; the existing open-source fallback was preserved.
• Built HTML: canonical and og:url both exactly https://doctorderek.com, with no stale WWW identity.
• Full local Playwright: 89/90 passed. WebKit startup fails at e2e/startup.spec.ts:72, waiting for the first Rive canvas. It failed identically in an isolated rerun and with both application URL owners temporarily restored to match origin/main; this failure is present without the hostname change. Approved bare-domain values were then restored. No animation or E2E code changed.
• ESLint passed (excluding only the preexisting untracked .pnpm-store/); all six changed files pass Prettier. Formatting was scoped to avoid unrelated churn.
• Diff review: exactly six intended files; no remaining tracked references to this site's WWW hostname.
• pnpm audit --prod is not clean: the unchanged dependency tree reports 3 high and 2 critical findings (browserslist, sharp, Next.js). Dependency remediation is outside this hostname PR; no packages or lockfile changed.

Scope preserved

Preview and localhost URLs, production-only analytics gating, third-party URLs, sibling portfolio subdomains, relative manifest paths, copy, styles, and application behavior remain unchanged. No new origin abstraction, redirect middleware, test framework, storage migration, or deployment pipeline. No conflicting canonical GDD hostname was found, so no authority documents were edited.

After merge

• Wait for the normal production deployment of this PR's merge commit.
• Verify the live bare homepage returns 200 and WWW redirects with 308, preserving path/query and valid HTTPS.
• Verify published canonical and Open Graph URLs use the bare domain; manifest/runtime assets load.
• Confirm the main-triggered Lighthouse run uses the updated bare-domain input.
