prism-merge 🏷️ v2.0.4

2.0.4 - 2026-02-22

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.
