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 is a simple package that helps read and write length-delimited slices. It's helpful for building wire protocols.
+
+## Usage
+
+### Reading
+
+```go
+import "github.com/libp2p/go-msgio"
+rdr := ... // some reader from a wire
+mrdr := msgio.NewReader(rdr)
+
+for {
+  msg, err := mrdr.ReadMsg()
+  if err != nil {
+    return err
+  }
+
+  doSomething(msg)
+}
+```
+
+### Writing
+
+```go
+import "github.com/libp2p/go-msgio"
+wtr := genReader()
+mwtr := msgio.NewWriter(wtr)
+
+for {
+  msg := genMessage()
+  err := mwtr.WriteMsg(msg)
+  if err != nil {
+    return err
+  }
+}
+```
+
+### Duplex
+
+```go
+import "github.com/libp2p/go-msgio"
+rw := genReadWriter()
+mrw := msgio.NewReadWriter(rw)
+
+for {
+  msg, err := mrdr.ReadMsg()
+  if err != nil {
+    return err
+  }
+
+  // echo it back :)
+  err = mwtr.WriteMsg(msg)
+  if err != nil {
+    return err
+  }
+}
+```
