Poem

A rabbit checks the version line,
From seventeen to eighteen fine.
The bridges shine in matching hue,
Each package hops to point-oh-two—
No, point-oh-eight, fresh and new!

-pub const CANONICAL_VERSION: &str = "0.17.0";
-pub const PYPI_VERSION: &str = "0.17.0";
+pub const CANONICAL_VERSION: &str = "0.18.0";


Refresh the program identity golden for 0.18.0

When the canonical version becomes 0.18.0, bex_vm_types/src/identity.rs still gates its cross-platform golden assertion on CANONICAL_VERSION == "0.17.0", so the assertion is skipped in every 0.18.0 test run. That test explicitly says its expected hash must be regenerated on a version bump; update its version guard and expected digest so changes to the program-identity framing remain covered.

Useful? React with 👍 / 👎.
