Release prep: 0.8.0 and a Linux riscv64 release build (#669)

* Release prep: bump to 0.8.0 and add a Linux riscv64 release build

- release.yml: new `linux-riscv64` job, ported from GridCraft. It cross-compiles on
  ubuntu-24.04 against riscv64 libraries from ports.ubuntu.com (the Linux job's X11/Wayland/GL
  -dev packages plus ALSA), ships effectcraft-<v>-linux-riscv64.tar.gz, and smoke-tests
  effectcraft-cli under qemu-riscv64. The draft-release job now needs it, so its tarball is
  uploaded and covered by SHA256SUMS.txt.
- packaging/linux/package.sh: cross-compiles when CROSS_ARCH/CROSS_TARGET/CROSS_COMPILE are set
  (cargo --target, the cross strip, the EMULATOR smoke test), as GridCraft's does.
- Version 0.7.0 -> 0.8.0 (cargo xtask version set), Cargo.lock refreshed.
- README and docs/releasing.md list the riscv64 tarball.

* Fix FreeBSD CI: pointer_wrap test harness, wasm32 target, clippy as_chunks

- pointer_wrap tests: the harnesses dropped run_ui's FullOutput with the font atlas upload still
  in textures_delta, and epaint 0.36's drop check panics on that in debug builds. Every
  pointer_wrap test failed on every platform; FreeBSD is the only CI that runs them. Clear the
  delta, as the other UI tests do.
- freebsd.yml: install wasm32-unknown-unknown in the VM. Without it the host plug-in test's build
  of examples/plugins/posterize-bands failed (E0463, no std) and the test skipped silently; now
  it builds and runs.
- media/convert.rs: chunks_exact(2) -> as_chunks::<2>() (clippy chunks_exact_to_as_chunks,
  new in Rust 1.99); same pairs, same dropped remainder.
