trail-mate/boards/tdeck

boards/tdeck

Board-owned home for T-Deck support.

Current responsibilities:

• own the boards::tdeck::TDeckBoard implementation
• own T-Deck-specific ESP adapter glue under boards/tdeck/platform_esp_board_runtime.h
• keep T-Deck bring-up, pin usage, and singleton/runtime behavior inside boards/tdeck/*

Boundary note:

• shared ESP board abstractions, display helpers, and dispatcher glue stay in platform/esp/boards
• T-Deck-specific runtime and board knowledge belongs in boards/tdeck
