[distribution] Add `--version` flag and embed build metadata in the CLI binary

[Gbangbolaoluwagbemiga]

Context

sanctifier --version currently prints the Cargo package version but no build information. Debugging production issues requires knowing the exact commit, build date, and target.

What to build

Use vergen or a build.rs script to embed:

sanctifier 0.1.0
Commit: abc1234 (2026-03-23)
Target: x86_64-unknown-linux-gnu
Built with: rustc 1.76.0

Acceptance criteria

• sanctifier --version prints version + commit SHA + build date
• JSON output includes "sanctifier_version" field in every report
• build.rs checks at compile time that CARGO_PKG_VERSION matches a semver tag pattern
