feat: upgrade eval pipeline with agentic runner, telemetry session, and savings meter

Add 9 capabilities to match IPW pipeline:

Eval Pipeline:
- AgenticRunner for multi-turn agent execution with per-turn trace decomposition
- QueryTrace/TurnTrace data model for agentic workload telemetry
- EventRecorder for thread-safe agent event collection
- TerminalBenchTaskEnv for Docker-based task execution
- Cost computation via engine/cloud.py PRICING table
- Rich export: JSONL, HF Arrow, summary JSON, artifacts manifest
- CLI: --agentic, --concurrency, --query-timeout flags

Telemetry:
- TelemetrySession with background-sampling ring buffer (Python fallback)
- Phase metrics: prefill/decode energy split at TTFT boundary
- ITL percentile tracking (p50/p90/p95/p99)
- FLOPs estimation and MFU computation
- EnergyMonitor.snapshot() method

Rust Performance Layer:
- Ring buffer with binary search O(log n) window queries
- Trapezoidal energy integration
- Phase metrics, ITL stats, FLOPs estimation in Rust
- PyO3 bindings for all new telemetry modules (50 Rust tests)

Savings Meter & Benchmarks:
- Use-case benchmark datasets (coding, email, research, knowledge, morning brief)
- Savings dashboard component with cost comparison visualization
- Cloud cost calculator and comparison server routes
- Use-case eval configs for multiple agent/engine combinations

Tests: 80 new tests (3779 total pass, 37 skipped, 0 failures)
Lint: ruff check src/ tests/ — all checks passed
