fix(agent): resolve gadget callbacks without heavy executor scans

[darjss]

Why

Dashboard onGadgetChat callbacks blocked on the agent for up to 113s because the agent re-fetched live erxes data on every chat message. Workers RPC waits approach ~180s.

Scope

• packages/workshop-backend/src/agent.ts: agentCallback replay prompt tells the agent to resolve from callback args without EXECUTOR unless live data is required. Target under 30 seconds.

Blast Radius

Agent prompt only. Affects gadget chat callbacks, not normal user messages.

Verification

Prompt string change only; no automated test for replay text.

Summary by Sourcery

Resolve gadget callbacks promptly without invoking executor tools unless live data is required.

Bug Fixes:

• Speed up gadget chat callback handling by resolving from callback arguments and existing request context before fetching live data.
• Prevent executor tools from being available during callback-initiated agent turns, avoiding unnecessary executor scans.

Reviewer's Guide

Updates the agent’s callback replay prompt so gadget chat callbacks resolve from supplied arguments without expensive executor scans unless live data is necessary, reducing callback latency while leaving normal user-message behavior unchanged.
