feat: JSON Schema format support (v1.2.0)

Add JSON Schema as the 8th supported format in SchemaForge.

- JSONSchemaParser: reads JSON Schema  into Schema IR
  (tables→definitions, columns→properties) with full type mapping
  (string, integer, number, boolean, object, array, date-time, uuid, enum)
- JSONSchemaGenerator: outputs JSON Schema draft 2020-12 from IR
  with  per table, required arrays, enum lists, maxLength,
  defaults, descriptions, and  for single-table schemas
- 29 new tests: parsing, generation, roundtrip, cross-format
  (SQL↔JSON Schema, Prisma), type config integration, edge cases
- Updated CLI: --from/--to and --format include json_schema
- Sample fixture: fixtures/sample.json_schema.json
- 189/189 tests passing

feat: custom type mapping configuration (v1.1.0)

Add TypeConfig class allowing users to override default type mappings
per format via YAML/JSON config files with template variable support.

- TypeConfig: load from .yaml/.yml/.json, merge, template variable
  resolution ({length}, {precision}, {scale}, {values})
- CLI: --type-map option for schemaforge convert
- All 7 generators (SQL, Prisma, Drizzle, TypeORM, Django, SQLAlchemy,
  Alembic) forward type_config through resolve_type/build_type_string
- has_type_override helper lets generators skip special-case formatting
  when an override is active
- 282-line test suite: unit tests, file loading, merge, integration
  tests across 3 formats, roundtrip fidelity verification
- Sample fixture: fixtures/sample-type-overrides.yaml
- 160/160 tests passing
