Yichen Jiang beaace5eb3 Merge remote-tracking branch 'origin/master' into codex/rfc-subagent-background-tasks
Adopts #185 (dsh-timeout: clampTimeout/deadline/timeoutOf drive bash
run() timeout classification; runBash loses its own timer) and #108
(ask_user_question) across the task-runtime rework: bash-local keeps
the BashProcess handle shape with master's deadline mechanics, tool
catalogs/expectations carry both the task_* and ask-user tools, and
generated docs are regenerated on the union.

util/ — low-level shared utilities

Zero-dependency primitives shared across the other groups. A package lands here when it owns a tiny, foundational type or helper that several capability families need but that belongs to none of them — keeping it out of any one group avoids a capability package depending on an unrelated one just to reach a shared primitive. These are support packages: small, stable, and free of harness dependencies.

Package Role
brand/ The type-only Branded<B> nominal-typing primitive (no runtime code, no harness deps)
timeout/ The timing/classification half of a timeout — clampTimeout/deadline/timeoutOf/TimeoutReason (pure functions, no harness deps); termination stays in each capability

dsh-brand is the canonical case: it owns ONLY the Branded<B> helper, so a capability package can brand the ids it owns (dsh-tasks's TaskId, dsh-session's SessionId, …) by depending on dsh-brand alone, without pulling in an unrelated package just to reach Branded.

dsh-timeout follows the same shape for the timeout family: dsh-bash and dsh-web-fetch-local each fuse a caller's cancellation with a deadline and later classify "timed out" vs "cancelled" by depending on dsh-timeout alone. It deliberately owns only the timing/classification half — the termination (SIGKILL a process group, tear down a fetch socket) stays in each capability, because no shared layer can own every capability's kill (see the timeout-library RFC).
