feat(P05): Phase 05 verification + traceability (T-5.3, T-5.4)

---ci---
phase: 5
milestone: v1.0
status: execute
persona: lead-developer
task: T-5.3
requirements:
  covered: [REQ-13, REQ-14, REQ-15]
---/ci---

Wave 3, task T-5.3 + T-5.4. scripts/verify_phase05.sh checks: (1)
evidence-ui/index.html structure (inline CSS/JS, fetch ./audit.json,
no external refs, refresh button, 8134 bytes); (2) run_demo.sh syntax
+ --no-upload flag; (3) run_demo.sh --no-upload (4 acts, exit 0,
audit.json written); (4) audit.json content (11 events + Act 1/2/3/4 +
Act 4 POLICY_VIOLATION rejection); (5) hash chain integrity; (6) no
stray state.json/contracts in repo root; (7) REAL upload + raw URL
fetch (audit.json 200 with 11 events, index.html 200 with ACDL Evidence
markers). All 13 checks PASS.

The demo is live at:
  https://git.cloudinit.dev/continuous-intelligence/acdl-evidence/raw/branch/main/index.html

Traceability: REQ-13/14/15 -> covered (pending VERIFY). ROADMAP Phase 05
-> executing.
