platform/shared

Platform-neutral contracts and utilities shared across multiple runtime families.

Current responsibilities:

• shared board-facing contracts under include/board/*
• shared lightweight board utilities that are not tied to a single platform runtime

Boundary note:

• code under this package must not depend on platform/esp/* or platform/nrf52/*
• platform-specific runtime dispatch, display glue, and board selection stay under their platform roots
• concrete board implementations stay under boards/<name>/*
