v4.7.1

Bug fixes

• #each context corruption — Variables like category or any
  post-level field could render empty inside {{#if}} blocks within an
  #each loop when a nested #each (e.g. #each1 tags) was also
  present in the same iteration body. Root cause was Promise.all
  concurrency allowing the shared contextStack to be mutated mid-read.
  Evaluation is now sequential within each iteration.

• Filters on this, @index, @key — These context references
  could not be piped to filters (e.g. {{this | slugify}}), causing a
  parse error. They are now fully pipeable like any other expression.

Internal

• Added .gitattributes to enforce consistent LF line endings across
  all text files.
• Update README and LICENSE date
