torlando-agent[bot]andClaude Opus 4.8 70d4aa6be9 feat: graft pyxis onto upstream microReticulum 0.4.1
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.
