[feat] add optional README toggle and prepend kata/solution links in language-aware comments

[fcoterroba]

• What kind of change does this PR introduce? (Bug fix, feature, docs update, etc.)

  • Feature update (with minor behavior adjustment) to support a more flexible Codewars-to-GitHub sync format.

• What is the current behavior? (You can also link to an open issue here)

  • CodeHub creates a README.md for each kata by default and uploads only the raw solution content.
  • For users organizing their repo as language/kata-name/mysolution.ext, README creation may be unnecessary, and solution files currently do not include direct links to the kata/source context.

• What is the new behavior (if this is a feature change)?

  • Adds a new optional setting to enable/disable per-kata README.md creation.
  • Keeps existing folder-structure options, including support for:
    • language/kata-name/mysolution.ext
  • Prepends metadata comments to the uploaded solution file (using language-appropriate comment syntax) with:
    • original Codewars kata URL
    • GitHub URL to the saved solution file
    • Preserves previous behavior for users who keep README creation enabled.

• Does this PR introduce a breaking change? (What changes might users need to make in their application due to this PR?)

  • No breaking changes expected.
  • Existing users can continue using current settings unchanged.
  • The only visible difference is the new optional README toggle and solution header comments in uploaded files.

• Screenshots or screen recording (if appropriate):
