Remove empty `Details#initialize` method in endpoint.cr

[hahwul]

Description

src/models/endpoint.cr (lines 130–131) defines an empty initialize method for the Details struct:

struct Details
  include JSON::Serializable
  include YAML::Serializable
  property code_paths : Array(PathInfo) = [] of PathInfo
  property status_code : Int32?
  property technology : String?

  # + New details types to be added in the future..

  def initialize
  end
  ...

Since all properties already have default values (empty array and nil), Crystal will auto-generate a no-arg initializer. The explicit empty def initialize; end is redundant.

Additionally, the comment on line 128 has a minor formatting issue — trailing double periods (..) and a + prefix.

Suggested fix

- # + New details types to be added in the future..
-
- def initialize
- end

If the comment is still relevant, clean it up:

# New details types can be added in the future.
