feat: benchmark local Ollama models against 50 tok/s threshold (#287)

Add scripts/benchmark_local_models.py — tests all local Ollama models
against the 50 tok/s UX threshold (configurable via --threshold).

Features:
- Auto-discovers all pulled Ollama models or test specific ones
- Configurable rounds, max tokens, threshold
- Per-round timing with prompt_eval/eval token breakdown
- Human-readable table report with PASS/FAIL/ERROR status
- JSON output mode (--json) for CI integration
- Exit code 1 if any model fails threshold

Usage:
  python3 scripts/benchmark_local_models.py                 # all models, 3 rounds
  python3 scripts/benchmark_local_models.py --models qwen2.5:7b  # single model
  python3 scripts/benchmark_local_models.py --json          # CI output
  python3 scripts/benchmark_local_models.py --threshold 30  # custom threshold

Tested: gemma3:1b scores 141.8 tok/s (PASS).

Closes #287

-"""Warm Session Provisioning — pre-proficient agent sessions.
-
-Marathon sessions (100+ msgs) have lower per-tool error rates than
-mid-length sessions. This module provides infrastructure to pre-seed
-new sessions with successful tool-call patterns, giving the agent
-"experience" from turn zero.
-
-Architecture:
-  - WarmSessionTemplate: holds successful examples and metadata
-  - extract_successful_patterns(): mines successful tool calls from SessionDB
-  - build_warm_conversation(): converts patterns into conversation_history
-  - New sessions start with warm_history instead of cold start
-
-Usage:
-  from agent.warm_session import (
-      WarmSessionTemplate,
-      extract_successful_patterns,
-      build_warm_conversation,
-      save_template,
