v0.1.2 — workflow v0.64.0 dep bump (picks up contract-diff + lockfile…

refactor: inject plugin version at build time via ldflags

Replace hardcoded Version string in Manifest() with a package-level
var that goreleaser populates via -ldflags -X. This ensures the
plugin's reported Manifest().Version matches the release tag, so the
workflow engine's requires.plugins[].version check passes.
