feat: dashboard integration from remote machines (SSH tunnel for Redis + DB)

[dougss]

Problem

When running claw on a remote machine (e.g., iMac Pro), executions don't appear in the dashboard because Redis (127.0.0.1:6379) and PostgreSQL (127.0.0.1:5432) are bound to loopback on the mini.

Current warnings on remote machines:

[ioredis] Unhandled error event: Error: connect ECONNREFUSED 127.0.0.1:6379
[warn] could not register run in DB (dashboard won't show it)

Options

Option A — Per-execution SSH tunnel (alias)

alias claw='ssh -fNL 6379:127.0.0.1:6379 -L 5432:127.0.0.1:5432 mini 2>/dev/null; CLAW_ENGINE_DATABASE_URL="postgresql://claw_engine:claw_engine_local@127.0.0.1:5432/claw_engine" /path/to/node $(which claw) "$@"'

Option B — Persistent tunnel with autossh (recommended)

brew install autossh
autossh -M 0 -fNL 6379:127.0.0.1:6379 -L 5432:127.0.0.1:5432 mini
export CLAW_ENGINE_DATABASE_URL="postgresql://claw_engine:claw_engine_local@127.0.0.1:5432/claw_engine"

Acceptance Criteria

• Executions from iMac appear in dashboard at http://192.168.1.100:3004
• Redis events stream correctly to dashboard SSE
• Task registered in DB with correct metadata
• Document setup in CLAUDE.md
