chore: Add .npmignore for clean npm package

Exclude development files from npm package:
- Source files (src/, tests/, benchmarks/, examples/)
- Development tools (.claude/, .claude-flow/, .hive-mind/, memory/)
- Scripts and databases (scripts/, *.db)
- Documentation (docs/, CLAUDE.md)
- Build configs (tsconfig.json, jest.config.js)

Package size: 21.7 MB → 55.4 kB (235 kB unpacked)
Files: 292 → 52

Keeps only essential runtime files (dist/, README, CHANGELOG, LICENSE).
