feat(autoresearch): standalone experiment runner + result store (#2597)

[mrveiss]

Summary

Milestone 1 of #1440 (AutoResearch integration). Implements the standalone experiment runner and result store foundation.

Components

• models.py — Experiment, ExperimentResult, HyperParams, ExperimentStats dataclasses with full serialization
• config.py — AutoResearchConfig with env-var overrides (AUTOBOT_AUTORESEARCH_*)
• parser.py — Extracts val_bpb, train/val loss, tokens/sec from autoresearch training output
• store.py — Dual persistence: Redis (timeline queries, state indices) + ChromaDB (semantic search over findings)
• runner.py — Subprocess-isolated experiment execution with timeout, auto-evaluation (keep/discard based on improvement threshold)
• routes.py — REST API: GET /experiments, GET /experiments/{id}, GET /experiments/stats, POST /experiments, POST /experiments/baseline, GET /status, POST /cancel
• Router registered in feature_routers.py at /api/autoresearch

Architecture

• Follows existing service patterns (composition, lazy init, dependency injection)
• Uses canonical get_redis_client() and get_async_chromadb_client()
• No hardcoded IPs or values — all config via env vars + SSOT

Test plan

• 28 unit tests passing (parser, models, config, store)
• Manual: curl -sk https://localhost:8443/api/autoresearch/status after deploy
• Integration: Run actual training on .20 GPU node (requires autoresearch repo clone)

⚠️ SSOT Configuration Compliance: Violations Found

Metric	Count
Total Violations	2
SSOT Violations (high priority)	1
Other Violations	1

⚠️ 1 values have SSOT config equivalents!

These should be replaced with SSOT config imports:

Python:

from src.config.ssot_config import config
# Use: config.vm.main, config.port.backend, config.backend_url

TypeScript:

import config from '@/config/ssot-config'
// Use: config.vm.main, config.port.backend, config.backendUrl
