Contrat
- assert z.coerce.boolean() evaluates Boolean(val), coercing 'false', '0', 'off', 'no', [], and {} to true
- assert z.coerce.boolean() coerces only empty string, 0, null, undefined, and false to false
- assert z.coerce.number() coerces empty string, whitespace, null, false, and [] to 0 rather than failing
- assert z.coerce.number() rejects undefined as invalid_type with received NaN
- assert z.coerce.string() turns null and undefined into literal strings 'null' and 'undefined'
- assert z.coerce.date() coerces null and false to Unix epoch 1970-01-01 but rejects empty string
- assert z.coerce.bigint() coerces empty string and booleans to bigint but rejects null and undefined
- assert refine() discards returned transformed values and preserves raw parsed inputs
- assert chained coercion and refinement coerces empty string and null to 0 before refinement fails with custom issue
