I'm concerned this could pick up previous build artifacts from the cache. Why not have the build script of the protocol/standards crates write the package output to $CARGO_MANIFEST_DIR/../target/$PROFILE/<package>.masp (you may need to adjust the the number of ../ segments based on the folder hierarchy of each crate).

Then you will always know that after building those crates, the .masp files under target/$PROFILE/ will be the exact ones you requested

cp "$(find target/release/build -path '*/out/assets/miden-standards.masp')" standards.masp

- Simplified the `ownable2step` ownership transitions ([#3170](https://github.com/0xMiden/protocol/pull/3170)).
- Fixed `note_script_allowlist::assert_all_input_notes_allowed` and `tx_script_allowlist::assert_tx_script_allowed` to read the allowlist from the transaction's initial storage state via `active_account::get_initial_map_item` ([#3182](https://github.com/0xMiden/protocol/pull/3182)).

### Enhancements

- Added a CI release job that uploads the pre-built `protocol.masp` and `standards.masp` packages to the GitHub release page to aid `midenup`'s installation speed ([#2859](https://github.com/0xMiden/protocol/pull/2859)).
