fix: route subagent announce through correct agent in delegation context

[duhd-vnpay]

Summary

• Bug: When a delegated agent spawns subagents, the announce results fail with agent default not found because the scheduler's RunFunc only parses agent:{agentId}:{rest} session keys
• Root cause: Delegate session keys use format delegate:{uuid8}:{targetAgentKey}:{delegationId} — the delegate: prefix was not handled, causing fallback to "default" (which doesn't exist in managed-mode DBs)
• Fix: Add delegate: case to the session key parser in makeSchedulerRunFunc, extracting the agent key from position 2

Details

gateway_consumer_process.go:makeSchedulerRunFunc resolves which agent loop to use from the session key. It only handled:

agent:{agentId}:{rest}

But subagent announces within delegations use session keys like:

delegate:019cd724:ui-ux-design-agent:1a93a73f-795

This caused repeated errors:

ERROR "subagent announce: agent run failed" error="agent default not found: agent not found: default"
WARN  "unknown channel for outbound message" channel=delegate

The fix adds a switch/case on parts[0] to handle both agent: and delegate: prefixes.

Test plan

• Build succeeds (docker compose build goclaw)
• Container starts healthy (docker compose up -d goclaw)
• Trigger a delegation that spawns subagents → verify announce routes to correct agent (no more agent default not found errors)
• Verify normal agent: session key routing still works (direct chat via Telegram/Zalo)

PR #124 Decomposition Summary

This PR bundles multiple unrelated changes (38 files, +2765 LOC) and has conflicts with main. We've extracted and re-implemented each fix group as focused PRs on main:

Merged

• Cron context injection (c5b8860 on main) — ExtraSystemPrompt now tells the agent about the cron job's requester, channel, and delivery target. Also fixed cron.create from Web UI to capture userID.

Open PRs

• PR fix: route delegate session keys to correct agent loop #127 fix/delegate-session-key-routing — Handles delegate: session key prefix in consumer routing (was causing "agent default not found" errors for delegated runs)
• PR fix: auto-persist cleaned history when orphan tool messages detected #128 fix/orphan-history-cleanup — sanitizeHistory now returns dropped count and auto-persists cleaned history, preventing repeated warnings on every request. Adds SetHistory() to session store.
• PR fix(zalo): download CDN media to temp file and handle []byte credentials #130 fix/zalo-media-credentials — Downloads Zalo CDN photos to temp files (auth-restricted/expiring URLs), adds PhotoURL field support, fixes []byte credentials handling in Update()

Deferred

• Party Mode (~20 files) — New feature, not a fix. Will be a separate PR when ready. Has open issues: missing authorization checks on session handlers, snake_case/camelCase event field mismatch.

Closing this PR in favor of the focused PRs above.
