Integrate BACKBEAT SDK and resolve KACHING license validation

Major integrations and fixes:
- Added BACKBEAT SDK integration for P2P operation timing
- Implemented beat-aware status tracking for distributed operations
- Added Docker secrets support for secure license management
- Resolved KACHING license validation via HTTPS/TLS
- Updated docker-compose configuration for clean stack deployment
- Disabled rollback policies to prevent deployment failures
- Added license credential storage (CHORUS-DEV-MULTI-001)

Technical improvements:
- BACKBEAT P2P operation tracking with phase management
- Enhanced configuration system with file-based secrets
- Improved error handling for license validation
- Clean separation of KACHING and CHORUS deployment stacks

+
+This package enables listening and dialing from _the same_ TCP or UDP port.
+This means that the following sockopts may be set:
+
+```
+SO_REUSEADDR
+SO_REUSEPORT
+```
+
+This is a simple package to help with address reuse. This is particularly
+important when attempting to do TCP NAT holepunching, which requires a process
+to both Listen and Dial on the same TCP port. This package provides some
+utilities around enabling this behaviour on various OS.
+
+## Examples
+
+
+```Go
+// listen on the same port. oh yeah.
+l1, _ := reuse.Listen("tcp", "127.0.0.1:1234")
+l2, _ := reuse.Listen("tcp", "127.0.0.1:1234")
+```
+
+```Go
+// dial from the same port. oh yeah.
+l1, _ := reuse.Listen("tcp", "127.0.0.1:1234")
+l2, _ := reuse.Listen("tcp", "127.0.0.1:1235")
+c, _ := reuse.Dial("tcp", "127.0.0.1:1234", "127.0.0.1:1235")
+```
+
+**Note: cant dial self because tcp/ip stacks use 4-tuples to identify connections, and doing so would clash.**
+
+## Tested
+
+Tested on `darwin`, `linux`, and `windows`.
