v0.4.1 — submission-ready

Submission-ready build.

Tool descriptions are now descriptive rather than instructional. deck_syntax said "Read this BEFORE writing or editing a deck" and write_deck said "Call deck_syntax first" — both are instructions about how Claude should behave rather than statements of what the tool does, and Anthropic's directory review rejects descriptions that tell Claude to go call something else. They now state what they are and name the reference tool instead.

No functional change. Install deck-0.4.1.mcpb below via Settings → Extensions → Install Extension.
