Eliminates SQLite write contention across the host-container mount
boundary by splitting the single session.db into two files, each with
exactly one writer:
inbound.db — host writes (messages_in, delivered tracking)
outbound.db — container writes (messages_out, processing_ack)
Key changes:
- Host uses even seq numbers, container uses odd (collision-free)
- Container heartbeat via file touch instead of DB UPDATE
- Scheduling MCP tools now emit system actions via messages_out
(host applies them to inbound.db during delivery)
- Host sweep reads processing_ack + heartbeat file for stale detection
- OneCLI ensureAgent() call added (was missing from v2, caused
applyContainerConfig to reject unknown agent identifiers)
Verified: tsc clean, 327 tests pass, real e2e through Docker works.

- Use DELETE journal mode for session DBs instead of WAL. WAL doesn't
sync reliably across Docker volume mounts (VirtioFS), causing dropped
writes and duplicate deliveries.
- Add 20s idle detection to end the query stream. The concurrent poll
tracks SDK activity via a new 'activity' provider event. When no SDK
events arrive for 20s and no messages are pending, the stream ends
and the poll loop continues.
- Add touchProcessing heartbeat so the host can distinguish active
agents from idle ones by checking status_changed recency.
- Catch query errors in the poll loop and write error responses to
messages_out instead of crashing the process.

Add the v2 data layer: typed interfaces, central DB with migration
runner, per-entity CRUD, and agent-runner session DB operations.
- src/log.ts: concise message-first logging API
- src/types-v2.ts: AgentGroup, MessagingGroup, Session, MessageIn/Out
- src/db/: connection (WAL), migration runner, 001-initial schema,
CRUD for agent_groups, messaging_groups, sessions, pending_questions
- container/agent-runner/src/db/: session DB connection, messages_in
reads + status transitions, messages_out writes
- 31 new tests, all 277 tests pass
