Major Refactor: RDM Discovery & Device API Stabilization

This release introduces a significant refactor of the RDM subsystem, stabilizing the device API and restructuring discovery handling. The changes aim to improve maintainability, consistency across modules, and future extensibility.

RDM Discovery Redesign

• Introduced new RDM headers:
  • rdm_device_base.h
  • rdm_device_info.h
  • rdm_discovery.h
• The legacy rdmdiscovery implementation has been refactored and renamed to:
  • rdm_discovery_statemachine
• Discovery logic and constants were reorganized and namespaced.
  New RDM Device API
• RDM device access has been migrated to structured types:
  • rdm::device::Base
  • rdm::device::Info
• Updated all call sites to use the new API.
• UID, serial number, and label handling now use the new device structures.

Configuration Store Changes
The configuration storage layout has been updated:
Changes

• Replaced set_list fields with flag-based configuration.
• Added helper:
  • RdmDeviceCopyArray
• Corrected array update signatures and sizes.
  Field Updates
• label → port_name
• Buffer sizes adjusted to match the new naming.

Build system

• Removed GCC optimization flag: -fprefetch-loop-arrays

Miscellaneous

• Updated copyright years → 2026
• Minor formatting and include cleanups
• Variable rename:
  • type → kType
• Simplified Sync() implementation to a one-line function.
• Reordered RDM conditional logic in:
  • lib-pixeldmx/Rules.mk
