Engines and stores

Tier: Internal

These crates exist so the installable CLI and runtime compile. They are not a supported public library API. Depending on them couples you to internal refactors without a curated changelog.

Area	Crates
Browsers / workers	`worker-pool`, `firefox-companion`, `companion-*`
Page / session / intents	`page-runtime`, `session-manager`, `intent-engine`
DOM / JS / network	`dom-engine`, `js-engine`, `network-engine`
Persistence	`artifact-store`, `checkpoint-store`, `workflow-journal`, `task-scheduler` (in-process queue + optional JSONL journal; broker exposes `POST/GET/DELETE /v1/jobs` with `job:*` capabilities; not a public library API)
Gateways	`mcp-gateway`, `cdp-gateway`
Other	`skill-runtime`, `observability`, `config` (config is shared but still alpha)

Public Rust consumers should stick to:

bobby-browser-client + types (Supported)
interface-core / sdk-core / broker only when embedding (Embed)
