The daemon ships as a PyInstaller one-file binary; its direct parent is the
bootloader, which the Rust supervisor (mesh/reticulum.rs Drop) stops via
start_kill() == SIGKILL. SIGKILL can't be forwarded, so the Python child was
orphaned on every link recreation and kept holding the RNode serial port.
These stale daemons piled up (9 seen on one node), all clutching /dev/ttyUSB0
and garbling the RNode so it silently stopped transmitting (txb frozen,
interface status False).
Set PR_SET_PDEATHSIG(SIGTERM) at daemon startup so the kernel signals us when
the parent exits; our existing SIGTERM handler then shuts down cleanly and
frees the port. Linux-only, best-effort, no-op elsewhere.

Merges in the meshtastic agent's now-finished work alongside this session's
continuation: stock-peer (3ccc) PKI-capability is now stamped through
get_contacts -> refresh_contacts -> MeshPeer.pkc_capable, so a directed DM to/from
a PKC-capable stock Meshtastic peer correctly shows the E2E pill on the Sent row,
not just received messages. Confirmed live: .198 sees "Meshtastic 3ccc" with
pkc_capable=true.
Also fixes two real interop/correctness bugs found while live-testing the
Reticulum <-> Sideband link:
- Receive: the daemon only ever read LXMF's plain-text content, silently
dropping native FIELD_IMAGE/FIELD_FILE_ATTACHMENTS fields — a stock
Sideband/NomadNet photo vanished into a blank-space message. Now decoded
into the same ContentInline typed envelope our own attachments use.
- Send: images to a non-archy (stock) peer now use native LXMF FIELD_IMAGE
instead of our own opaque CBOR wire format, which Sideband can't decode.
- Root cause of a garbled MC-chunk-fragment bug: TypedEnvelope.v/.sig (the
OUTER wrapper every message type uses) serialized raw bytes as a CBOR
array-of-integers instead of a native byte string, bloating every
message on the wire ~2-3.5x — enough to push even a tiny ReadReceipt
over the 140-byte single-frame chunking threshold. Root-caused by
reading ciborium's deserializer source directly (deserialize_bytes only
works within its internal scratch buffer; deserialize_byte_buf streams
unbounded).
Frontend: consolidated the attach/record buttons into a single animated "+"
menu (was overflowing the compose row).
857/857 tests pass. Verified live across all 5 deploy-roster nodes.

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.
