chore: prepare v0.1.2 release — pre-generate protobuf modules

Move the protoc build-time dep removal into its own release so
behavioral changes to the consumer build flow are clearly attributed.

v0.1.1 stays scoped to the jason dep drop + README cleanup.

 - **Dropped the `jason` dependency** in favor of the built-in `JSON` module
   (Elixir 1.20+). All encode/decode call sites in `lib/` and `test/` now use
   `JSON.encode!/1` / `JSON.decode/1`. `jason` remains only as a transitive
