Steno engine with BLE split-storage architecture
Full steno engine: chord detection, MPHF/trie dict lookup, Plover
formatter (18 commands), undo (ring buffer), HID + Unicode output.
Split-storage specific:
- BLE GATT service for dict queries (query/prefix/batch)
- LRU cache on central side (CONFIG_STENO_SPLIT_CACHE_SIZE)
- Dict embedded on peripheral, engine runs on central
- 3-way dispatch: split_dict / MPHF / simple trie
Build system: auto-fetch Plover dict, MPHF compiler with block
compression (~56K entries in 420KB), CMake integration.
