feat(compound-engineering): session orchestrator, persistence, resume (U5)
Add ce_sessions schema (onSchemaInit), CeSessionStore (via ctx.taskStore.getDatabase()), and CeOrchestrator driving a stage's skill on the U4 interactive seam: streams thinking/text, persists questions as awaiting_input, writes the stage artifact on complete, and auto-saves + emits an observable event on interrupt/error (never silent loss). Lifecycle: launching/active/awaiting_input/completed/error/interrupted with resume and an interval-relative staleness rubric. Start/answer/resume/get-state routes. Streaming transport is client polling of the get-session-state route for v1: plugin routes have no native SSE and the loader emitEvent is a logging stub, so true server push needs a host publish-to-/api/events seam (tracked follow-up). Skill discovery is cwd+prompt-based; forwarding install paths through the seam is a tracked follow-up.
