[FEATURE] Agent Execution Analytics Dashboard

[AbhinaavRamesh]

Is your feature request related to a problem? Please describe.
Currently, GenAI AgentOS provides basic execution tracing, but it would be helpful to have more comprehensive analytics to:

• Debug more easily — Visualize the Master Agent's decision path and see where time is spent
• Track costs — Monitor token consumption and spending across agents/models
• Spot trends — Identify slow agents and compare performance over time
• Understand usage — See which agents are popular and how they're being used
• While the current logging works fine for most cases, having a dedicated analytics view would make optimization and monitoring more convenient.

Describe the solution you'd like
A native Analytics Dashboard in the frontend with:

• Execution history — Paginated list of past queries with timing and status
• Summary metrics — Cards showing execution count, avg response time, success rate
• Token/cost tracking — Usage breakdown by agent, model, and user
• Query inspector — Drill into individual executions to see the ReAct loop and token breakdown
• Export options — CSV/JSON export for offline analysis

Describe alternatives you've considered

• External tools (Grafana, Datadog) — Works but requires extra setup; not everyone needs that level of infra
• Enhanced logging — Simpler, but lacks visualizations and trend analysis
• Third-party platforms (Langfuse, LangSmith, etc.) — Feature-rich but could add cost and external dependencies

Additional context
A lightweight native solution fits the self-hosted philosophy of AgentOS without requiring additional tooling.
