v0.1.0

feat: prebuilt binary distribution via GitHub Releases

Release workflow builds static musl binaries for x86_64/aarch64-linux
(zig-linked) and native aarch64/x86_64-darwin, publishes them as release
assets, and commits an SRI-hash manifest (nix/binaries.json) back to main.
The flake exposes falcon-bin (fixed-output fetch of the release tarball,
no compilation, immune to nixpkgs.follows overrides) and prefers it as
packages.default once the manifest covers the system; source-built falcon
remains the escape hatch and the basis of all checks.
