fix(atlas): allow task and call_omo_agent tools for subagent dispatch

[code-yeongyu]

Problem

Atlas agent cannot dispatch subagents because the task and call_omo_agent tools are blocked by tool restriction configuration.

Root Cause

In atlas/agent.ts, tool restrictions incorrectly deny access to delegation tools.

Fix

Update tool permission configuration to allow Atlas to use task and call_omo_agent tools.

Validation

• bun test src/agents/ --timeout 30000
• bun run typecheck
• bun run build

Closes #2044
