fix: include skills/ directory in published npm package

[yodablocks]

Closes #152

Problem

The skills/ directory (27 skill files) was missing from the published npm package because package.json's files allowlist never included skills/**. Every version since launch has shipped without skills files.

Fix

Added "skills/**" to the files array in package.json.

Verification

Ran npm pack --dry-run — skills/ files now appear in the tarball output.

Note

This also unblocks PR #260, which adds new skill files to skills/ that would otherwise be invisible to npm users until this packaging bug is fixed.

Tests

All tests pass, lint clean.

Summary

This is a minimal, well-targeted bug fix. The PR adds "skills/**" to the files array in package.json, ensuring the skills/ directory (containing ~28 skill subdirectories with SKILL.md definitions used by AI agents) is included when the package is published to npm. Without this entry, the skills directory was silently omitted from the published package. A correctly scoped changeset entry (patch) accompanies the change. No issues found.
