NodeSlide: complete governed presentation control system

[HomenShum]

Summary

• completes the governed NodeSlide agent loop: multi-agent handoffs, durable jobs/sessions, one-session Turbo authority, hard spend ceilings, CAS/idempotency, bounded live Deck REPL validation, and human-readable traces
• adds immutable evidence custody: exact-byte uploads, source revisions, claim receipts, screenshot/PDF region scope, lazy PDF.js overlays, owner data export, and fail-closed cleanup
• makes approved CSV/JSON/TXT uploads model-readable through owner/session-gated Convex storage, digest verification, quarantine approval, bounded extraction, and source revision binding
• completes editor/landing UX consolidation: AI Elements composer, current model/provider-native effort selection, attachments/web/memory/scope controls, compact review queue, responsive inspector, 4/10/100/1,000-span waterfall, and accessible dialogs
• preserves editable structured output, Deck CI, PPTX/Google/JSON/MCP reconciliation, native edit persistence, publish gating, and deterministic fallback truthfulness
• includes digest-bound self-authored dogfood proof: seven-slide deck, browser WebM/GIF, v1→v2 acceptance receipt, final screenshot, and editable PPTX export

Known non-blocking build notes

• Vite reports the pre-existing vendor/react circular chunk and large-chunk advisories; PDF.js is lazy-loaded and the production build succeeds.
