cmdBuzz: take a profile like its siblings - #67

Conversation
cmdBuzz was the only cmd builder in commands.dart with no BandProfile param, so it always built a gen4 frame no matter what band it was really going to. no live bug today (ble_engine branches around it with cmdBuzzGen5Maverick) but any future generic caller passing profile: gen5 would silently get a gen4 crc8 frame a real gen5 strap can't parse. same fix as cmdGetBattery/cmdAbortHistorical/etc got earlier.

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.

cmdBuzz was the only cmd builder in commands.dart with no BandProfile
param. every other builder (cmdLinkValid, cmdGetBattery, cmdSetAlarm,
etc) takes
{BandProfile profile = BandProfile.gen4}and forwards itinto buildCommand so it can pick gen4 crc8 vs gen5 crc16-modbus
framing. cmdBuzz missed that, so it always built a gen4 frame.
no live bug today, edge's ble_engine.dart branches on isGen5 itself
and calls cmdBuzzGen5Maverick separately. but cmdBuzz is a public
export with the same shape as its gen5-aware siblings, so any future
generic caller passing profile: gen5 would silently get a gen4 frame a
real gen5 strap can't parse.
added a profile param (positional optional, matching buildCommand's
own [payload, profile] shape) and a gen5-framing test alongside the
existing cmdGetBattery/cmdAbortHistorical profile tests.
Summary by Sourcery
Make cmdBuzz profile-aware so it supports gen5 command framing consistently with the other command builders.
