Implement Sociosphere and Prophet Workspace adapters for workspace/workroom state

[mdheller]

Agent work order

@copilot @codex please implement this after PR #1 lands or by branching from seed/agentterm-chatops-core if instructed.

Goal

Add adapters that let AgentTerm display and request Sociosphere workspace state and Prophet Workspace workroom bindings without taking ownership of either plane.

Context

• Sociosphere owns canonical workspace manifests, locks, topology, governance registry metadata, validation lanes, and release-readiness orchestration.
• Prophet Workspace owns workspace product semantics, Professional Workrooms, app surfaces, policy-aware UX, audit, and receipts.
• AgentTerm is the terminal operator surface and normalized event log.

Required scope

• Add adapter interfaces/events for Sociosphere manifest, lock, topology, validation, and materialization status.
• Add adapter interfaces/events for Prophet Workspace workroom binding, validation, audit/receipt references, and context hydration requests.
• Preserve Matrix room/thread, workroom ID, policy decision references, topic scope, memory context-pack reference, and evidence refs where available.
• Add fake backend tests; do not require live Sociosphere or Prophet Workspace services in CI.

Non-goals

• Do not move Sociosphere manifest/topology authority into AgentTerm.
• Do not define Prophet Workspace product semantics in AgentTerm.
• Do not hydrate workspace context without Policy Fabric admission.
