Fixed

• Always preserve destination magic comments (# frozen_string_literal: true,
  # encoding: UTF-8, etc.) at the top of merged output, regardless of merge
  preference. Magic comments are file-level metadata managed by Prism and must
  not be lost when the template side lacks them (e.g. after filtering).
  emit_dest_prefix_lines now detects contiguous magic comments from the first
  destination node's leading comments, emits them before any template-only nodes
  (Phase 1), and records the emitted line numbers so add_node_to_result and
  merge_node_body_recursively skip them to prevent duplication.
• Non-top-of-file magic comments (e.g. used as documentation) are left alone and
  treated as regular comments.
• Fix blank line preservation between magic comments and subsequent comments when
  template preference is used. Gap lines between a stripped magic comment and the
  next remaining comment are now correctly emitted from the template source.
• Fix inter-node gap line preservation when a matched node is output from the
  template source. perform_merge now checks whether the output source's
  analysis had a trailing blank before advancing last_output_dest_line, so
  emit_dest_gap_lines correctly emits dest gap lines that the template lacked.
