Instance DSL parties — multiplicity, validation, and enforcement#89
Merged

Conversation
Adds `parties do` DSL to the Instance Extension, allowing resources to declare which party roles they accept, with optional min/max multiplicity constraints. Runtime enforcement is applied in `build_before` via `Party.validate_parties/1`, checking roles against declarations and rejecting builds that violate constraints. Renames Party Extension DSL sections from singular (`instance`/`party`) to plural (`instances`/`parties`) for consistency. Replaces `.license` sidecar files with `REUSE.toml`. Fixes ExDoc sidebar by removing a duplicate `docs:` key in mix.exs that shadowed the DSL extras config. Adds `Assignment.compare/2` so `Enum.sort/2` works in the Assigner. Updates all three livebooks to use the local path dep and cleans up stale commented-out version pins. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
