Select the gen5 haptic command for gen5 profiles.

cmdBuzz always sends Cmd.runHapticsPattern (0x4F). Gen5 uses Cmd.runHapticPatternMaverick (0x13) with the 12-byte payload [0x01, 47, 152, 0, 0, 0, 0, 0, 0, 0, 0, overallLoop]. Route gen5 calls to that builder and assert the opcode and payload in test/gen5_command_surface_test.dart.

minimal, and validate.

In `@lib/src/commands.dart` at line 289, Update cmdBuzz to select
Cmd.runHapticPatternMaverick for gen5 profiles, using the required 12-byte
payload with overallLoop in the final position, while preserving the existing
command for other profiles. Add or update assertions in
gen5_command_surface_test.dart to verify the gen5 opcode and payload.
