0.12.1

Fixed

• 0.12.0 could not be consumed as a git dependency. The workspace was cut at 0.12.0 with every crate's path dependencies still requiring 0.11.0; the gate passed on a working tree whose manifests were bumped and left uncommitted, so entity-store 0.12.0 required an entity-core the same tag no longer had. The manifests are committed at 0.12.1, and a test now reads every path = "../…", version = "…" line against the workspace version, so a tag cannot leave with its own crates disagreeing about which release they are.
