Why
Bun lockfile pruning could drop a hoisted transitive dependency when a target workspace also used a newer nested version of the same package. That left the pruned lockfile accepted by Bun but resolving a dependency outside its declared semver range.
What
Fix Bun package key parsing for deeply nested package keys so pruning preserves the correct parent-child relationship for each nested dependency. Add a regression test and a check-lockfiles fixture based on issue #12962.
How
Verified with:
cargo test -p turborepo-lockfilescargo fmt --checkcargo build -p turbopnpm check-lockfiles --fixture bun-nested-major-mismatch --turbo-path ../target/debug/turboPre-push hooks also passed on push.
