fix(warhacker): make shallow launch endpoint genuinely mode-aware + real per-run receipts

Root cause: the self-contained /warhacker/launch/{problem} handler returned an IDENTICAL receipt for mode=nominal and mode=tamper (constant id, no real tamper test). It now DELEGATES to the REAL, mode-aware exhaustive-demo engine (szl_warhacker_demos): STL robustness rho, PolyCARP-style geofence, conformal interval, SHA-256 Merkle chain + Rekor-style inclusion proof, DSSE-signed breach event with the in-image ECDSA-P256 key. Receipt id is a real SHA-256 over the per-run DSSE PAE + chain hash + mode + decision, so it differs every run. Added chain_self (live-run own chain re-verified intact, NO tamper) to all 5 demos and a 'live chain' panel block + renderChainSelf() in pages/warhacker.html. Honesty labels preserved: cannonico=REAL TODAY; tychee/hangar2apps/cyber_rts/raven=ROADMAP (substrate real / vertical = sample data). Sovereign: zero CDN.
