Root cause: Bytes objects stored in PSRAM-allocated BLEInterface had
corrupted shared_ptr members from uninitialized memory, causing crashes
in processDiscoveredPeers(). Fixed by using heap_caps_calloc instead of
heap_caps_malloc for PSRAM placement-new allocation.
Additional fixes:
- Reduce pool sizes to fit memory budget (reassembler 134KB→17KB,
fragmenters 8→4, handshakes 32→4, pending data 64→8)
- Store local MAC as BLEAddress struct instead of Bytes to avoid
heap allocation in PSRAM-resident object
- Move setLocalMac after platform start (NimBLE needs to be running
for valid random address), add lazy MAC init fallback in loop()
- Add stuck-state detector: resets GAP state machine if hardware
is idle but state machine thinks it's busy
- Enhance getLocalAddress with 3 fallback methods (NimBLE API,
ble_hs_id_copy_addr RANDOM, esp_read_mac efuse)
- Fix C++17 structured binding to C++11 compatibility
- Increase BLE task stack 8KB→12KB for string ops in debug logs

Split T-Deck firmware from microReticulum examples/lxmf_tdeck/ into its
own repo. microReticulum is consumed as a git submodule dependency pinned
to feat/t-deck. All include paths updated from relative symlinks to bare
includes resolved via library build flags.
Both tdeck (NimBLE) and tdeck-bluedroid environments compile successfully.
