feat(ci): bake CalVer version into released binaries (#4)

## Summary - Add `build.rs` that runs `git describe --tags --always` and sets `ANVIL_VERSION` at compile time - Clap reads `ANVIL_VERSION` for `--version` output instead of `CARGO_PKG_VERSION` - CI bootstrap-builds once (to get the anvil binary for release.sh), computes the CalVer version, creates a local git tag, then rebuilds so the version is baked into the released binary - Dev builds report git SHA (`anvil 9ff9d8e`), release builds report CalVer (`anvil 2026.04.2`) ## How it works The local tag only exists inside the CI container — it never gets pushed. The server-side tag is created by `anvil release create --tag $VERSION`. No commits to main, no branch protection issues, no CI loops. Refs #1 ## Test plan - [x] Local build without tags → reports git SHA - [x] Local build with tag → reports tag - [x] fmt, clippy, tests pass - [ ] CI publishes release with version-stamped binary
