Minor Changes

• #​1758 6b46b04 Thanks @​threepointone! - Add progress signalling and durable milestones for agent-tool sub-agents
  (#​1758, rfc-detached-agent-tools §progress, phases 4a + 4b).

  A sub-agent running as an agent tool (awaited or detached/background) can now
  report mid-run progress:

  // Inside the child sub-agent (e.g. from a tool's execute):
  await this.reportProgress({
    fraction: 0.6,
    phase: "deploying",
    message: "Generating menu page…",
  });

  These signals ride the child's own turn stream as a transient
  data-agent-progress part, so they re-broadcast to the parent's connected
  clients and surface on AgentToolRunState.progress via useAgentToolEvents — a
  background-runs tray can render a live bar / phase / status line without drilling
  in. Highlights:

  • reportProgress({ fraction?, message?, phase?, data? }, { persist? }) on
    chat agents (@cloudflare/think, AIChatAgent); a no-op with a dev warning on
    the base Agent and when called outside an active agent-tool run. The framework
    resolves the run id from the active turn — no threading required. Bursts are
    coalesced (latest-wins; a fraction >= 1 "done" frame always flushes). data
    is live-only unless { persist: true }.
  • onProgress(run, progress) parent hook, fired best-effort from the tail
    for both awaited and detached runs.
  • Latest-snapshot persistence + recovery inspect. The child stores a
    progress_json + last_signal_at on its run row and surfaces it through
    inspectAgentToolRun().progress, so a rehydrated parent reconstructs progress
    after eviction.
  • Resetting no-progress budget for detached runs. Once a detached child has
    reported at least one signal, the backbone gives up if it then goes silent for
    detachedNoProgressBudgetMs (default 1h; per-run override via
    detached: { noProgressBudgetMs }), surfaced as interrupted with the
    no-progress reason. A child that never reports is bounded only by the absolute
    detachedMaxBudgetMs ceiling — we never give up on a run merely for being slow.
