…ency

- bradygaster#431: Empty/whitespace args show abbreviated help (confirmed, kept defensive guard)
- bradygaster#429: Version output unified to bare semver across all entry points
  - cli-entry.ts: --version, -v, and new 'version' subcommand all output bare semver
  - cli.js: Fixed stale hardcoded version, now uses getPackageVersion()
  - Shell: Added /version slash command returning bare semver

Fixes bradygaster#431, bradygaster#429
