* Release prep: bump to 0.3.0; add linux-riscv64 release job
- release.yml: new linux-riscv64 job (cross-compiled on ubuntu-24.04 against ports.ubuntu.com
riscv64 libraries, tar.gz only, CLI smoke-tested under qemu-riscv64), ported from GridCraft;
the release job needs it so SHA256SUMS covers its tarball.
- packaging/linux/package.sh: CROSS_ARCH / CROSS_TARGET / CROSS_COMPILE / EMULATOR support.
- Version 0.2.0 -> 0.3.0 (cargo xtask version set), Cargo.lock refreshed.
- docs/releasing.md, docs/hardware-parity.md: list the riscv64 tarball.
