v0.6.9

Added

• Add public pt-BR meal-estimator eval set at docs/evals/pt-br-meal-estimator.json with 52 Brazilian Portuguese meal examples across breakfast, lunch, snacks, dinner and churrasco-style meals.
• Add npm run test:pt-br-meal-eval, enforcing matched foods, unresolved terms, confidence ranges, calorie ranges, required categories and Brazilian kitchen units.

Fixed

• Treat unidade / unidades like serving-based pieces instead of 1g, so phrases such as 1 unidade de banana estimate one banana-sized serving.
• Add common pt-BR aliases used by everyday logs: café, leite, aveia, salada verde, arroz integral, frango desfiado and frango assado.

Verification

• npm test
• npm audit --audit-level=low
• npm pack --dry-run
• GitHub CI and CodeQL on f83e88d
