validate: --quality --json drops quality details from Rosetta JSON output

[noahgift]

Bug

apr validate model.gguf --quality --json outputs JSON but drops quality details (NaN count, Inf count, all-zero tensors, physics constraints) that are shown in the non-JSON output.

Root Cause

In crates/apr-cli/src/commands/validate.rs, line 100 returns early for JSON without passing quality:

if json {
    return print_rosetta_validation_json(path, &report, format);  // no quality param
}

// Non-JSON path correctly uses quality:
if quality {
    print_quality_constraints(&report);
}

print_rosetta_validation_json() at line 261 doesn't accept a quality parameter.

Expected Behavior

When --quality --json is used, the JSON output should include physics constraints:

{
  "quality": {
    "total_nan": 0,
    "total_inf": 0,
    "all_zero_tensors": [],
    "physics_constraints": "PASS"
  }
}
