Mint Restart Feature

A new command has been added to restart the CDK mints after recompiling, perfect for development workflows when you're making changes to the mint code.

Command

just restart-mints

./misc/regtest_helper.sh restart-mints

What It Does

Stops both running mints (CLN and LND mints)
Recompiles the cdk-mintd binary with your latest changes
Restarts both mints with the same configuration
Waits for both mints to be ready and responding
Updates the state file with new process IDs

Development Workflow

Before this feature:

# Terminal 1: Start environment
just regtest

# Terminal 2: Make code changes, then manually restart everything
# Ctrl+C in Terminal 1 (stops entire environment including Lightning network)
just regtest  # Start everything again (slow)

With this feature:

# Terminal 1: Start environment (once)
just regtest

# Terminal 2: Make code changes, then quickly restart just the mints
just restart-mints  # Fast! Keeps Lightning network running
just mint-test      # Test your changes

Benefits

Faster Development Cycle - No need to restart the entire Lightning network
Preserves Network State - Bitcoin blockchain, Lightning channels, and node states remain intact
Automatic Recompilation - No need to manually run cargo build
Status Validation - Ensures mints are responding before completing
State Management - Updates process IDs for other commands to work correctly

Example Output

✅ Mints restarted successfully!
  CLN Mint: http://127.0.0.1:8085 (PID: 54321)
  LND Mint: http://127.0.0.1:8087 (PID: 54322)
===============================

Use Cases

Testing mint code changes without restarting the entire regtest environment
Debugging mint behavior with fresh mint instances
Performance testing with clean mint state but preserved Lightning network
Integration testing after mint code modifications

This feature makes the development experience much smoother when working on CDK mint functionality!
