v1.2.0

py, js, and dart merged from separate repos/submodules into this
monorepo, with full git history preserved — see
docs/DESIGN-schema-unification.md for the design behind this release.

py/

Changed

• Validation now runs against the shared schema/a7p.schema.json via
  schema_validator.py (fastjsonschema-compiled, jsonschema fallback
  for full error lists) instead of the hand-written yupy_schema.py
  (kept temporarily, unused by the public API, as a reference/safety net)
• proto/profedit.proto now lives once at the repo root instead of a
  local copy under proto/

js/

Changed

• Validation now runs against the shared schema/a7p.schema.json via a
  compiled, standalone ajv validator (src/generated/a7p_schema_validator.cjs,
  regenerated by scripts/build_schema_validator.mjs) instead of yup —
  yup and @types/yup are gone; ajv is a devDependency only (used by
  the codegen script, not shipped)
• proto/profedit.proto now lives once at the repo root instead of a
  local copy under src/proto/
• License changed from ISC to LGPL-3.0, matching dart — both generate
  bindings from the same LGPL-3.0-sourced proto/profedit.proto

Added

• First test suite (test/validate.test.ts, 10 tests) covering the same
  categories as dart's validator tests

Fixed

• zoom was unbounded (accepted 0–255); now bounded to 0–6, matching the schema
• bc_cd/mv for CUSTOM drag models were capped ×10 too low
• b_length minimum was 1 instead of 10
• ValidationError was imported from yup, not this package's own
  errors.ts — error instanceof ValidationError checks in index.ts
  never matched a validation failure as a result; fixed as part of the
  yup removal

dart/

Changed

• Validation now runs against the shared schema/a7p.schema.json via the
  json_schema package instead of hand-written A7pValidator/
  A7pFieldConstraints range checks — the schema is embedded as a
  generated Dart string constant (lib/src/generated/a7p_schema.g.dart,
  regenerated by python scripts/compile.py --dart), since no
  standalone-codegen JSON Schema validator exists for Dart
• c_zero_distance_idx no longer bounds dynamically by distances.length - 1; now the static 0–255 range, matching py/js
• proto/profedit.proto now lives once at the repo root instead of a
  local copy under proto/

Added

• Test suite (test/a7p_validator_test.dart, 9 tests) covering real
  protobuf Payload objects, including the c_idx 201–254 gap and mv
  uniqueness
• "Dimensions" table in README.md (previously missing, unlike py/js)
