Upstream tagged v0.3.1; refresh src and cargo hashes (dependencies
changed between the two tags). Verified with nix build .#awgen and
result/bin/awgen --version.
Upstream tagged v0.3 (3d10c5f) in alex/awgen. The dependency set is
unchanged, so cargoHash stays the same; only the source hash needed a
recompute for the new tag.
Verified: nix build .#awgen is green, cargo checkPhase reports 29 passed
/ 0 failed, and the resulting binary runs. Upstream Cargo.toml still
declares 0.1.0, so `awgen --version` prints 0.1.0 while the derivation
version (taken from the tag) is 0.3.
Package alex/awgen (offline, stateless Rust CLI for AmneziaWG configs) from
the upstream Gitea repository. Source is fetched with fetchFromGitea and
pinned to the v0.1 tag; the cargo dependency hash is pinned as well.
Also list the package in the README package table and project tree.
