Show provider subagents in the subagents track (#2013)

* Add provider-owned subagent stream contract * OpenCode provider: detect child sessions, attach adopted children to the hosting server, synthesize external turns - Emit internal provider_child_session_detected / provider_session_deleted stream events from the global event stream (before the no-active-turn gate), including BFS hydration of existing descendants on subscribe - Track child sessions in a registry mapping child session id -> hosting server url; resumeSession attaches via acquireExisting() so adopted children share the parent's server generation and keep receiving live events - Synthesize external turns for adopted (externally driven) sessions so timeline, tool calls, and permission requests stream without a Paseo-initiated prompt - Honor launchContext.env in resumeSession (acquireDedicated parity with createSession) - Stop folding child tool parts into the parent's sub_agent action log; the parent row stays as a pointer * Render provider subagents in workspace timelines * fix provider subagent timeline reliability * fix provider subagent lifecycle edge cases * fix provider subagent event fidelity * Fix provider subagent history fidelity * Fix restored provider subagent state * Fix provider subagent visibility edges * Restore provider subagent timelines * Page provider subagent history * Forward subagent questions reliably * fix(subagents): preserve OpenCode child context * fix(subagents): harden provider timeline routing * fix(subagents): preserve provider page continuity * fix(subagents): retain live child prompts --------- Co-authored-by: Omer <639682+omercnet@users.noreply.github.com>
