v0.5.4

AI Craftery Bord v0.5.4

Hotfix for v0.5.3.

What's fixed

The aicraftery-diagram skill shipped in v0.5.3 was installed in the
wrong location (~/.claude/plugins/aicraftery/skills/diagram/ instead
of ~/.claude/skills/aicraftery-diagram/). Claude Code, Codex and
Gemini only auto-discover slash commands from the second path, so
/aicraftery-diagram never appeared in chat autocomplete and agents
in fresh sessions kept writing class-diagram.md files with mermaid
code fences instead of .mmd files that the new viewer can open.

This release moves the skill to the correct install path. After
updating, open a fresh chat session and /aicraftery-diagram will be
available; asking the agent to "draw UML classes for X" will produce
a .mmd file in the chat cwd that opens straight in the diagram
viewer.

No other functional changes from v0.5.3.
