/**
 * Creates a TOML codec.
 *
 * TOML has no null type, so null values are recursively stripped on encode.
 * Missing keys naturally become undefined on decode.
 *
 * @returns A FormatCodec for TOML serialization
 *
 * @example
 * ```typescript
 * const codec = tomlCodec()
 * const layer = makeSerializerLayer([codec])
 * ```
 *
 * @remarks
 * - Null/undefined values are stripped on encode (TOML has no null)
 * - TOML dates are returned as Date objects by smol-toml
 * - TOML arrays must be homogeneous; mixed-type arrays will throw on encode
 * - Schemas with required nullable fields (NullOr) won't round-trip through TOML
