Implement knowledge and intelligence adapters: Slash Topics, Memory Mesh, New Hope, Sherlock Search, Holmes, MeshRush

[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 adapter lanes for the knowledge/intelligence runtime surfaces while preserving each plane's authority boundary.

Required scope

• Slash Topics: topic scope selection, topic-pack validation references, membrane decision events, receipt refs.
• Memory Mesh: governed recall/writeback/context-pack request and result events.
• New Hope: semantic message/thread/claim/citation normalization event shapes.
• Sherlock Search: search-packet validation/hydration request and result events.
• Holmes: request/status/artifact correlation only; respect docs/integration/holmes-boundary.md and do not redefine Holmes semantics.
• MeshRush: graph-view/diffusion/crystallization request/status/evidence event shapes.
• Preserve workroom, topic scope, Matrix room/thread, Agent Registry agent ID, Policy Fabric decision refs, and evidence refs where available.
• Add fake backend tests; do not require live services in CI.

Non-goals

• Do not move Slash Topics, Memory Mesh, New Hope, Sherlock Search, Holmes, or MeshRush schemas into AgentTerm.
• Do not implement legacy Sherlock OSINT as ambient tooling.
• Do not hydrate sensitive context without Policy Fabric admission.
• Do not dispatch non-human participants without Agent Registry resolution.
