ASSISTANT-WORKSPACE-MVP (Guided Workspace Entry) & ASSISTANT-CONTRACT (Workflow Metadata Surface)

Release digest

ASSISTANT-WORKSPACE-MVP (Guided Workspace Entry) — Shipped the first visible assistant workspace slice as a product surface:
- /app/assistant now exposes guided starter briefs for company, crypto, and contract-forensics research
- the workspace keeps conversation history, live transcript, latest workflow summary, and direct handoff actions in one route
- company analysis flows now surface report, overview, and watchlist next steps directly inside the assistant rail
ASSISTANT-CONTRACT (Workflow Metadata Surface) — The live /api/ai/chat response now exposes additive execution workflow metadata for workspace-aware rendering:
- execution.workflow.action_type
- execution.workflow.entity_ref
- execution.workflow.suggested_next

CHAT-COMPANY-ALIGNMENT (Deterministic Trust Score Path) — Production company analysis now stays aligned with the canonical Trust Score contract:
- live SAP analysis returns the canonical 72/100 score instead of a drifted variant
- the same production path now returns workflow-ready handoffs for report, overview, and watchlist follow-up
CHAT-LANGUAGE-WIRING (German Response Path) — Deterministic company analysis now respects the German language contract in production instead of falling back to Ukrainian or English wording

Live production verification against sentry-app-00568-6cj confirmed that /app/assistant renders the guided workspace shell and that the company starter brief returns the canonical SAP analysis plus three handoff actions.
Snapshot contract drift for the dashboard assistant surface was re-synced and pushed through CI.
Updated the public AI assistant page to reflect guided starter briefs and the workspace handoff rail.
Updated the knowledge base AI chat guide with the dedicated workspace route and additive execution metadata contract.
Regenerated changelog app content from the canonical root CHANGELOG.md.
