docs(site): surface current proof spine and public discovery metadata

[raylee-hawkins]

Summary:

• Adds a scan-fast Current Proof Spine homepage section for strongest recent HawkinsOperations work.
• Surfaces reviewer metrics, HO-DET-001 receipt chain, Lifetime Case Ledger v1, Runtime Case Collector v0, Runner Trust Split, Standing Governance Controls, and Proof Pack 001 Quick Check.
• Adds public discovery metadata under robots, /.well-known, agent.md, and deployment headers for reviewer/agent navigation.
• Preserves all proof boundaries and blocked claims through the site contract verifier.

Validation:

• git diff --check
• npm run check:site
• npm run typecheck
• npm run build

Proof boundary:

• Website rendering and public navigation only.
• No proof promotion.
• No runtime-active claim.
• No signal-observed claim.
• No public-safe runtime proof.
• No production/SOCaaS/customer deployment claim.
• No FortiSIEM integration-proven claim.
• No autonomous SOC / AI disposition / analyst disposition claim.

Reviewer note:

• This PR improves reviewer discoverability before the MUFG final interview.
• It does not change underlying proof authority, validation authority, runtime truth, signal truth, evidence truth, or public-safe status.

Reviewed PR #56 for reviewer-facing impact, current-truth alignment, mobile stability, and proof-boundary safety.

Confirmed this PR now:

• Surfaces the Current Proof Spine as a proof-controlled detection operations model.
• Shows current Lifetime Case Ledger truth as 6 governed cases / 6 ledger events.
• Keeps Reviewer Metrics Pipeline v1 activity metrics separate from governed case count.
• Surfaces HO-DET-001 receipt chain, Lifetime Case Ledger, Runtime Case Collector private candidate lane, Runner Trust Boundary, Standing Governance Controls, and Proof Pack 001 reviewer route.
• Reframes Detections from portfolio/card language into source -> validation -> proof-ceiling language.
• Preserves AI as support-only and avoids SOCaaS/product-readiness wording.
• Fixes mobile Artifacts scroll/rendering risk and optimizes the mobile hero asset.

Validation reported passing:

• git diff --check
• npm run check:site
• npm run typecheck
• npm run build
• stale-count scan
• Proof Pack pending scan
• Runtime Route Proof wording scan
• blocked-claim scan
• private/local leakage scan
• route/anchor checks
• mobile browser checks for homepage and artifacts
• GitHub build, required-files, and Cloudflare Pages checks

Proof boundary:
Website rendering and reviewer navigation only. No proof promotion, runtime-active claim, signal-observed claim, public-safe runtime proof, production/SOCaaS/customer deployment claim, FortiSIEM integration-proven claim, autonomous SOC, AI disposition authority, or analyst disposition authority.

Approved for final merge consideration after Raylee visual preview.
