docs: remove stale run_autobot.sh references across codebase

[mrveiss]

Problem

run_autobot.sh does not exist (deprecated per Issue #863, moved to legacy/), but 20+ files still reference it in docs, scripts, and agent configs.

Key locations (non-archive)

• docs/system-state.md (line 1514)
• docs/developer/INFRASTRUCTURE_DEPLOYMENT.md
• docs/developer/AGENT_OPTIMIZATION.md
• docs/architecture/SSOT_CONFIGURATION_ARCHITECTURE.md
• autobot-infrastructure/shared/scripts/README.md
• autobot-infrastructure/shared/tests/performance/run_baseline.sh
• .claude/agents/frontend-engineer-agent.md

Many more in analysis reports and architecture docs.

Suggested Fix

Replace run_autobot.sh references with the correct startup method:

• systemctl start autobot-backend (production)
• scripts/start-services.sh start (CLI wrapper)
• docker compose up -d (Docker)

Discovered During

Parallel implementation of #2425/#2440/#2441/#2443 session.
