12db06cc26 Add auto-sweep hot wallet to cold storage (Task #4) 
New file: infrastructure/sweep.sh
- Reads /opt/timmy-node/sweep.conf (COLD_ADDRESS, KEEP_SATS=300000, MIN_SWEEP=50000)
- Queries LND on-chain confirmed balance via lncli walletbalance
- Calculates sweep_amt = balance - KEEP_SATS; skips if < MIN_SWEEP
- Sends via lncli sendcoins --addr $COLD_ADDRESS --amt $sweep_amt
- Logs timestamp, balance, sweep amount, txid to /var/log/timmy-sweep.log
- Triggers ops.sh backup after every successful sweep
- Exits cleanly (no crash) if conf missing, address unset, or balance too low

Updated: infrastructure/setup.sh
- Copies sweep.sh and ops.sh to /opt/timmy-node/ during bootstrap
- Installs two cron jobs: sweep at 3am UTC, backup at 4am UTC
- Creates /var/log/timmy-sweep.log and /var/log/timmy-backup.log
- Idempotent: removes existing timmy-node cron entries before re-adding

Updated: infrastructure/lnd-init.sh
- New "Cold Storage Auto-Sweep Setup" section after LNbits wallet creation
- Prompts for cold Bitcoin address (optional — skip to configure later)
- Writes /opt/timmy-node/sweep.conf with address + documented defaults
- sweep.conf chmod 600 (sensitive — contains sweep destination)
- Graceful skip path with instructions for later configuration

Updated: infrastructure/ops.sh
- New `sweep` command: shows sweep.conf config, current on-chain balance,
  last 5 lines of /var/log/timmy-sweep.log
- New `run-sweep` command: triggers sweep.sh immediately outside cron
- Help text updated with both new commands
