LeanHttp 0.3.1

Fixed

• Request.segment and Target.segment encode literal . and .. values as
  path data. Previously, resolution or libcurl could interpret a dynamic
  identifier as current- or parent-directory navigation.
• Relative target serialization preserves relative meaning for first segments
  containing :, leading empty segments, and an appended empty segment. It adds
  a dot prefix when needed instead of producing an absolute or scheme-relative
  reference, or dropping the distinction between an empty segment and no path.
• Relative fragments are percent-encoded on serialization, so spaces, #,
  Unicode, and literal percent characters round-trip through target parsing.
• Target.resolve removes literal dot segments from absolute target paths,
  matching its behavior for nonempty relative paths and preserving encoded dots.

Compatibility

• Public API signatures are unchanged. For intentional directory navigation,
  use reference syntax such as target!"../users"; .segment ".." now always
  supplies a literal path segment.
• The package version and default user agent are now 0.3.1 and leanhttp/0.3.1.
