sf-org-create.ps1 — wrapper for smart scratch org creation

USAGE:
  sf-org-create.ps1 -n <ORG_NAME> [-d <DAYS>] [-f <CONFIG_FILE>] [-a] [-t <TEMPLATE>] [-h]

OPTIONS:
  -n  Name/alias for the new scratch org (required)
  -d  Duration in days (default: 7, max: 30)
  -f  Path to scratch org definition file (default: config/project-scratch-def.json)
  -a  Set as default org alias after creation
  -t  Use predefined template (standard, testing, minimal, full)
  -h  Show this help

EXAMPLES:
  1) Create basic scratch org:
     sf-org-create.ps1 -n "MyDevOrg"

  2) Create testing org for 1 day:
     sf-org-create.ps1 -n "QuickTest" -d 1 -t testing

  3) Create with custom config and set as default:
     sf-org-create.ps1 -n "MainDev" -d 14 -f "config/custom-scratch-def.json" -a

  4) Create full-featured org:
     sf-org-create.ps1 -n "FullEnv" -t full -d 30

TEMPLATES:
  - standard: Basic scratch org with common features
  - testing: Optimized for running tests (minimal data)
  - minimal: Bare-bones org for quick tasks
  - full: All available features enabled

Notes:
- If no config file is specified, will look for config/project-scratch-def.json
- Templates override config file settings
- Org will be automatically opened in browser after creation
