fix: Format Go files per gofmt and goimports requirements

- doc.go: Convert spaces to tabs for proper Go formatting
- validator/validatorstest/test.go: Add validators import alias
- engine/chain/chaintest/test_blocks.go: Add consensustest import alias
- engine/chain/block/blocktest/test.go: Add consensustest import alias

These formatting fixes resolve all lint errors from golangci-lint.

 The Photon→Quasar consensus flow provides fast, quantum-secure finalization:
 
-  1. Photon Phase:  Emit proposals at light speed
-  2. Wave Phase:    Amplify through network via QZMQ
-  3. Focus Phase:   Converge on best options using AI
