feat: add the hackathon presentation layer

[chenmingtang830]

Summary

Ships the production presentation surface for the verified knowledge ledger:

• makes the light eight-beat presentation the primary entry experience;
• positions Proofpress as the verified knowledge ledger for autonomous AI agents;
• demonstrates the lifecycle from traces to governed, reusable knowledge;
• shows one large interactive graph with verified, human-review, and rejected paths;
• uses the existing Proofpress handoff study as bounded evidence;
• presents finance as the product workflow and agentic commerce as the extension surface;
• closes on verification as the prerequisite for trusted recursive self-improvement.

The earlier dark workbench is preserved under examples/verified-knowledge-ledger/archive/ rather than exposed in the presentation.

Production file set

• examples/verified-knowledge-ledger/demo.partner-style.html — final interactive presentation
• examples/verified-knowledge-ledger/archive/demo.partner-style.legacy-workbench.html — archived prior UI
• examples/verified-knowledge-ledger/README.txt — presentation and backend-fixture entrypoints
• docs/DESIGN.md — public visual and semantic-state contract

Iteration-only claims inputs and the stale event planning draft were intentionally removed before production merge.

Evidence boundaries

• Existing handoff study: stale reuse was 12/12 for ordinary handoff and 0/12 for Proofpress; unchanged continuation was 12/12 in both conditions.
• Finance values remain clearly labeled as an illustrative fixture.
• Agentic commerce reports the measured baseline separately from the proposed trust-overlay design target.
• Harvey / RelayBench calibration is not presented as a completed result.

Verification

• python3 proofpress.py verify examples/verified-knowledge-ledger/demo.partner-style.html — 3 verified
• python3 -m unittest tests.test_knowledge_ledger -v — 7 passed
• node --test tests/npm.test.js — 5 passed
• embedded JavaScript parsing — 5 blocks passed
• presentation contract — 8 slides / 8 note blocks
• git diff --check — passed
