Simplify debugging with human-readable agent and team identifiers

Agents and teams are now assigned human-readable IDs (e.g., brave-falcon-7x3k) instead of raw UUIDs.

This makes it significantly easier to identify and track specific runs at a glance across logs, traces, and monitoring dashboards without needing to cross-reference opaque identifier strings.

‍

Details:

Human-readable IDs are generated automatically for all agents and teams
Existing workflows referencing explicit session or agent IDs are unaffected
Improves legibility across AgentOS trace views, logs, and debugging output
