rainix-tag-release invokes rain.deploy's cutRelease() instead of reimplementing the freeze

+description: >-
+  Cuts a deploy repo's release snapshot: regenerates the rolling src/generated/candidate/ pins from the current source, formats, and only then freezes a byte-identical copy as src/generated/<tag>/ for the foundry.toml [package].version. The ordering is the reason this is a tool and not a consumer script — freezing before regenerating writes a stale candidate into a dir the frozen-snapshots-append-only gate protects forever while the regeneration moves candidate on, so the release publishes one address and permanently records another, and nothing downstream compares the two. Refuses a version that is not strict X.Y.Z (its tag dir would be invisible to that gate — an orphan snapshot nothing protects), a missing or empty candidate, and any tag dir that already exists.

Default `forge test`.
