Motoko doc strings

Purpose

Add triple-slash (///) doc comments to every public declaration in Motoko source files so that mo-doc renders meaningful documentation pages. This skill captures the conventions used in mo:core (caffeinelabs/motoko-core) and the lessons learned applying them across the motoko-bitcoin library.

When to Use

• The user asks to "add doc strings", "document the public API", or "generate docs" for a Motoko package.
• Reviewing or polishing a library before release / publication on MOPS.
• After adding new public symbols and noticing missing entries in the generated docs/.
