enricobuehler a913042367 feat: M1 lumen-core (FEC/crypto/packet/session + C ABI) and workspace scaffold

Ground-up low-latency streaming stack per docs/implementation-plan.md. M1 is
complete and tested; Linux host backends are cfg-gated stubs to be filled in on
real hardware (M0/M2).

lumen-core (built + tested on macOS/aarch64 — 21 tests):
- fec: ErasureCoder over GF(2^8) (reed-solomon-erasure, Moonlight-compatible)
  and GF(2^16) Leopard-RS (reed-solomon-simd, the >1 Gbps wall-breaker); proptested
- packet: zero-copy #[repr(C)] framing, multi-block, FEC-aware reassembly
- crypto: AES-128-GCM with per-direction nonce salts + sequence-as-AAD
- session: host submit / client poll hot paths + input; loopback & UDP transports
- abi: opaque handles, versioned LumenConfig, panic guards; cbindgen-generated header
- acceptance: Rust loopback+proptest and a C harness that links the staticlib

Scaffold (compiles green on all platforms): lumen-host (vdisplay/capture/encode/
inject/web/pipeline seams under cfg(linux)), lumen-client-rs, tools/{loss-harness,
latency-probe}, Apple/Android client stubs, Gitea CI, docs.

Hardened against a multi-agent adversarial review (13 verified findings fixed,
regression-tested): reassembler memory-DoS bounds + block-consistency validation,
GCM nonce-reuse direction separation, ABI struct_size guard + range checks, FEC
shard-length guards, shard_payload datagram bound, key zeroization + Debug redaction.

lumen Android client (later)

Kotlin UI + MediaCodec (decode) + a thin JNI layer over the lumen-core C ABI.

Wiring

Build the core as a shared library per Android ABI:

rustup target add aarch64-linux-android armv7-linux-androideabi x86_64-linux-android
cargo build -p lumen-core --release --target aarch64-linux-android   # liblumen_core.so

(Use cargo-ndk to handle the NDK toolchain/linker.)

JNI shim: small C/Rust glue mapping lumen_* to Kotlin external funs, bundling liblumen_core.so into the APK's jniLibs/.
Kotlin: client LumenSession → lumen_client_poll_frame on a decode thread → feed MediaCodec → render to a SurfaceView aligned to the display refresh.

Status

Placeholder — scheduled after the Apple client (M5).
