fix: make sub-agent cards launch markers

Sub-agent tool calls no longer accumulate the child's activity into
`log`. Claude, Codex, OpenCode, OMP and Pi emit the card when the child
starts and when its label or status changes; the child's messages and
tool calls stay in the sub-agent's own timeline. The app no longer
renders a sub-agent log.

The wire schema makes `log` optional. Daemons still send `log: ""` so
apps that require the field keep parsing the card.
