fix(release): the workspace crates' exact pins move with the version

91ec5fb bumped the workspace to 0.2.0 but left wallet-entities,
wallet-core and wallet-data pinned to each other at =0.1.0, so Cargo.lock
no longer resolved. The pins are now =0.2.0, the lockfile follows, and
script/stamp-version.sh rewrites the pins from the workspace version so
the next bump cannot leave them behind. Gate run with --locked.
