Merge remote-tracking branch 'origin/master' into codex/rfc-subagent-background-tasks

Adopts #220 (tool-cordis + the gen-cordis-api gate: the runtime API
catalog regenerated with ctx.tasks/onCleanup on it) and #225 (shared
transcript renderer). Tool-catalog expectations take the union
(cordis_* + task_*); packages/README budget adopts master's 660
ceiling, which absorbs both new group rows.
