fix: cron sessions inherit allowAgents from parent agent config (#1771)

When a cron job runs in isolated mode, the sessions_spawn tool now correctly
inherits the allowAgents permissions from the parent agent's config.

The fix adds a requesterAgentIdOverride parameter that flows through the
tool creation chain:
- resolveEffectiveToolPolicy() extracts the correct agentId from the session key
- This agentId is passed to sessions_spawn and agents_list tools
- The tools use this override instead of re-parsing the session key

This fixes #1767
