fix: Windows compatibility for npm scripts and cross-platform CI

Fixes #142 - Windows PowerShell install bug

Changes:
- Replace single quotes with escaped double quotes in generate:schemas
  (cmd.exe passes single quotes literally, breaking prettier glob matching)
- Simplify prettier scripts: remove redundant --ignore-path flags
  (prettier auto-loads .gitignore and .prettierignore by default)
- Remove $(pwd) from prettier scripts (bash-only syntax)
- Add cross-platform CI matrix: Linux x64, Windows x64, macOS ARM64, macOS x64
- Use shell: bash for grep commands in CI (not available in Windows cmd.exe)
