Detailed Description

Phase 3b templated channel facade – Channel<Bus, Chipset> with compile-time bus/chipset enforcement.

This header introduces the templated Channel<B, Chipset> form requested by issue #2428. It is intentionally a thin wrapper around the non-template fl::Channel runtime object so that:

• Existing Channel::create(cfg) callers and addLeds<>() subclasses of the non-template Channel keep working unchanged (zero source impact).
• The new templated entry point (Channel<B, Chipset>::create(cfg), FastLED.add<B, Chipset>(cfg)) enforces the Bus<->Chipset contract at compile time via static_assert(BusSupports<B, Chipset>::value, ...).
• Specifying an undefined Bus for the current platform produces a clean "implicit instantiation of undefined template `BusTraits<Bus::X>`" diagnostic rather than a silent runtime fallback.

The runtime polymorphic surface (IChannel, ChannelEvents callbacks, the ChannelManager registry) is unchanged – Channel<B, Chipset>::create() returns a ChannelPtr (shared_ptr to the existing non-template Channel) so everything downstream continues to see one channel type.
