Adds an additive, loopback-only TCP server/client interface to
reticulum-daemon and the Rust mesh wiring, alongside the unchanged serial
RNode path. Aurora (~/aurora) already speaks standard RNS/LXMF over plain
TCP by default, the same way Sideband already proved interop over LoRa
(docs/RETICULUM-TRANSPORT-PROGRESS.md gates #2/#3) — this closes the gap so
that interop is provable without scarce LoRa hardware, and gives archy a
path to eventually be dialed by an Aurora client.
Verified: daemon TCP transport round-trip, bidirectional LXMF DM against a
scripted RNS/LXMF stand-in for Aurora's Dart stack (content + dest-hash
match both directions), cargo check/test -p archipelago green (108 mesh
tests, 0 regressions), and a real MeshService::start() end-to-end test
spawning the daemon in TCP client mode with no serial probe.
TCP server mode is hard-gated to loopback in both Python and Rust — WAN/LAN
exposure is a deliberate future decision, not part of this change.

Phase 0 gates #2/#3 (two-node LXMF-over-LoRa, external Sideband interop) passed
on real hardware (.116's flashed Heltec V3 RNode <-> a phone-flashed RNode running
Sideband) — RNS announce, encrypted DM round-trip, and contact binding all verified
live. Fixed two bugs found in the process: the Reticulum send path wasn't stamping
outbound messages as E2E despite LXMF being unconditionally encrypted, and the
per-message transport pill collapsed Meshcore/Meshtastic into one generic "lora"
color instead of distinguishing the three radio transports.
Built on top of that link: a Columba-style image/file send experience —
compression-quality presets with a real transfer-time estimate (mesh.transport-advice,
now device-throughput-aware), receive-side thumbnail previews + auto-render for
already-local attachments, and async voice messages, all reusing the existing
ContentRef/ContentInline attachment pipeline. The headline addition is genuine RNS
Resource transfer support (daemon-side RNS.Link + RNS.Resource, Rust-side
send_resource/resource_recv plumbing, a new "resource-mesh" transport-advice tier)
so compressed photos up to 2MB now actually transfer over LoRa for Reticulum peers
instead of always falling back to Tor past the small inline-chunk cap.
