0.1.0 - 2025-12-27

String-keyed schema fields and nested object schema DSL (Schema.object/1).
Built-in format types (:date, :datetime, :uuid, :null, {:nullable, type}).
JSON encode/decode helpers with transform pipeline (Sinter.JSON, Sinter.Transform, Sinter.NotGiven).
Example runner examples/run_all.sh and refreshed example suite.

Big-bang refactor of core schema/validation architecture per technical design.
JSON Schema validation now uses jsv 0.13.1 with Draft 2020-12 default and Draft 7 provider support.
Provider JSON Schema generation applies strictness recursively for nested objects.
Schema inference avoids atom leaks by defaulting to string keys.

Switched JSON Schema validation to ex_json_schema v0.11.2.
Updated generated $schema to JSON Schema Draft 7 for validator compatibility.
Removed custom JSON Schema structural validation helpers in favor of meta-schema validation.
