## Summary - Export `findBbBinary` from `@aztec/bb.js` public API (was internal-only) - Use bundled bb binary in `aztec compile`, `profile-gates`, and `profile-flamegraph` commands - Resolution order: `$BB` env var > bundled binary > `$PATH` fallback ## Details When a user has a different version of `bb` installed globally (e.g. via `bbup`), `aztec compile` picks it up from `$PATH` instead of using the version bundled with the installation. This causes transpiler errors due to version mismatch. The fix uses the existing `findBbBinary()` helper from `@aztec/bb.js` which detects the platform and returns the path to `build/<arch>/bb`. This is the same approach already used by `@aztec/bb.js`'s own CLI wrapper.
