Subject: Scaffold Rust binary project with clap, CI, and tooling
X-Git-Url: http://quire.kejadlen.dev/?a=commitdiff_plain;h=8758c328c9287040c45a13a5bcf954bac34de405;p=quire.git

Scaffold Rust binary project with clap, CI, and tooling

Restructure from a minimal lib+main into a proper binary project
layout: library target with error types, separate binary target
under src/bin/quire/ with clap subcommands (serve, exec), CalVer
versioning via build.rs, integration tests, justfile, clippy config,
mutation testing config, and GitHub Actions CI/release workflows.
