Subject: [PATCH] feat: US-019 - Enable heartbeat by default in config

- Added HeartbeatConfig struct with Enabled field
- Added Heartbeat to Config struct
- Set default Heartbeat.Enabled = true in DefaultConfig()
- Updated main.go to use cfg.Heartbeat.Enabled instead of hardcoded true
- Added config tests verifying heartbeat is enabled by default

Acceptance criteria met:
- DefaultConfig() Heartbeat.Enabled changed to true
- Can override via PICOCLAW_HEARTBEAT_ENABLED=false env var
- Config documentation updated showing default enabled
- Typecheck passes (go build ./... succeeds)
- go test ./pkg/config -run TestDefaultConfig passes
