packages(zellij): track latest stable, build Rust via rustup (#198)

Per review: track the latest stable zellij rather than pinning to an old
release to match Fedora's Rust.

- Bump to 0.44.3 (latest stable; needs Rust 1.92).
- Build with a rustup-managed toolchain instead of Fedora's rust/cargo.
  The spec reads the Rust channel from the source's rust-toolchain.toml
  and installs exactly that, so a Version bump is all it takes to follow
  a new zellij — no coordinating with the chroot's Rust version.
- Extract the channel, remove rust-toolchain.toml, then install+default
  the toolchain explicitly (minimal profile, host target only) so cargo
  doesn't pull the wasm32/musl targets it lists; we only build the host
  binary crate (plugins stay prebuilt). Robust against rustup 1.28's
  change where `rustup show` no longer auto-installs.
- BuildRequires rustup + git; still needs COPR "internet access during
  builds". README version/notes updated.
