bug(setup): bridge-state.json missing from initial file scaffolding checklist

[Benotos]

Problem

Phase 2d (Balance & Runway Check) references daemon/bridge-state.json and expects it to exist with a specific initial structure:

{"in_flight":false,"txid":null,"amount_sats":0,"started_at":null,"last_status":"idle"}

However, the setup/init checklist (loop-starter-kit scaffolding) does not create this file. On first run, any code that reads or parses bridge-state.json will fail with a file-not-found error.

Steps to reproduce

1. Fresh install of loop-starter-kit
2. Run the first cycle
3. Phase 2d tries to read daemon/bridge-state.json
4. File does not exist → error or crash

Expected behavior

The setup script / init checklist should create daemon/bridge-state.json with the default structure shown above.

Suggested fix

Add to the scaffolding step:

echo '{"in_flight":false,"txid":null,"amount_sats":0,"started_at":null,"last_status":"idle"}' > daemon/bridge-state.json
