set_array replaced entire arrays and discarded their internal comments, including during no-op policy updates. This preserves comments for unchanged items without adding a public API.

Approach

• Return the original document for semantic no-op updates, preserving exact source and line endings.
• Capture array-item and closing trivia during parsing. Reuse unchanged items, including their lexical forms, and match duplicate values one occurrence at a time in their original order.
• Retain standalone closing comments. Remove comments attached to removed or replaced items, as agreed for this fix.
• Preserve nested array source inside inline tables, handle Unicode and multiline quote boundaries, and use stack-safe matching on JavaScript.

Includes API documentation, README guidance, and a changelog fragment. Public types and edit errors remain unchanged.

Closes #64
