v1.19.0

Added

• Subagent-style live supervision without progressTokens: wait and waitAll are now
  hard-capped at one 60s activity slice when the caller supplies no _meta.progressToken
  (explicit long timeoutSec values included). Every call returns a fresh snapshot — assistant
  tail, reasoning tail, last tool calls, todo counts — plus nextStep, so chaining waits streams
  a subagent-style transcript into the conversation. This also keeps every call under Claude
  Code's ~2-minute MCP auto-background threshold (CLAUDE_CODE_MCP_AUTO_BACKGROUND_MS), which
  previously made long blocking waits mute and invisible. With a progressToken the old blocking
  behavior is unchanged (explicit timeoutSec honored, default 600s).
• Richer timeout context: the PostToolUse delegation hook now includes the reasoning tail
  and the most recent tool-call lines in its timeout note, alongside the existing assistant tail
  and todo progress.
• Explicit-only agent triggers: agents/opencode-delegate.md and
  skills/opencode-routing/SKILL.md now activate ONLY on an explicit user ask (subagent,
  delegation, OpenCode worker, fan-out) — never proactively. README gains a dedicated section
  documenting how to invoke the opencode-delegate subagent (natural language,
  /opencode:delegate, direct Task call) and what it costs in main-thread tokens (~400-450 per
  supervision slice; all heavy work runs inside OpenCode).

Fixed

• e2e fan-out supervision chains multiple slice-capped waitAll passes instead of assuming one
  long blocking call reaches idle.
