Both are written by task_loop() (core 0) and read by stop() (core 1); volatile
gives no cross-core ordering. Use std::atomic<bool> to match the other shared
flags (_conn_state, _reconnected, _last_connect_attempt) and give stop()'s join
a well-defined happens-before.

- stop() now waits on a _task_done flag the task sets right before exiting,
instead of a fixed sleep. Closes a use-after-free window where an in-flight
connect() overrunning CONNECT_TIMEOUT_MS (slow DNS) could touch `this` after
~TCPClientInterface() freed it.
- _last_connect_attempt is now std::atomic<uint32_t> — it's read/written by
task_loop() (core 0) and handle_disconnect() (core 1).

The blocking WiFiClient.connect() ran on the main loop and stalled it for the
lwIP default (~18.5s) when the host was unreachable -- including the DNS lookup --
freezing the UI, so the screen took ~10s to wake. The 2-arg connect() also
ignored CONNECT_TIMEOUT_MS (that only bounds reads).
Move only the blocking connect() to a dedicated FreeRTOS task. read/write/frame
stay on the main loop exactly as before (unchanged low-latency data path -- the
link/Resource timing is untouched). An atomic _conn_state hands _client ownership
between the task (while CONNECTING) and the main loop (while CONNECTED) so they
never touch the socket concurrently. Bound the connect via the 3-arg connect()
and back off retries to 15s.
tests/hardware: wait_for_tcp_link() matched "started", keying on interface
startup rather than the actual connect. With the async connect that let the
harness drive the announce before the link was up, so the device's announce was
lost and the first direct message (bz2-probe) failed. Match "connected to".
Verified on a T-Deck: screen wake instant (connect off the main loop); e2e smoke
5/5 including bz2-on-receive.

Repins microReticulum + microLXMF onto the upstream-0.4.1 graft and adapts
pyxis to the new src/microReticulum/ layout and 0.4.x APIs. The far-diverged
0.3.0 fork's Resource/Transport/Identity work is subsumed by upstream's
reimplementation; only the still-needed fixes ride on the pinned branches
(PKCS7/HMAC/X25519 crypto -- proven byte-identical to python RNS 1.3.1 --
Packet link-proof callback, Identity short-sig guard, and the bz2 layer +
decompress-on-receive in Resource::assemble()).
Consumer-side changes:
- platformio.ini: pin microReticulum @2f21fee (pyxis-fixes-on-0.4.1) and
microLXMF @33760d0 (chore/microreticulum-0.4.1-layout); bump microStore
ceea8f5 -> c5fb69d (0.4.x requires the new BasicFileStore::init API);
-std=gnu++11 -> gnu++17 (upstream requires C++17).
- Namespace all microReticulum includes (angle + quote) to <microReticulum/...>
for the relocated layout; shim-local Utilities/Stream.h|Print.h preserved.
- Interface::send_outgoing now returns bool: update TCP/BLE/SX1262/Auto
overrides with correct success/failure returns.
- SDArchiveFileSystem::init(bool reformatOnFail=true) to match new microStore.
- Static Transport::get_path_table() -> path_table(); instance getter unchanged.
- Remove duplicate shim Cryptography/BZ2 (microReticulum provides it now; keep
lib/libbz2 as the ESP32 bzlib provider).
- patch_littlefs_paths.py: normalize microStore's LittleFS adapter paths to a
leading "/" -- ESP32 Arduino LittleFS rejects "./"-prefixed paths, which
silently broke the path store (no peer paths learned, all messaging blocked).
Validated on T-Deck Plus: builds (RAM 27.5% / Flash 77.7%), boots stable
(no WDT/panic), and a full on-device LXMF e2e (DIRECT + OPPORTUNISTIC +
bz2-compressed-Resource receive) passes 5/5.

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.
