sf-deploy.ps1 — PowerShell wrapper for ``sf project deploy start``

USAGE:
  sf-deploy.ps1 -to <ORG_ALIAS_OR_USERNAME> (-sr "<src1>,<src2>[,...]" | -dr <DIRECTORY>) [-ts "<Test1>,<Test2>[,...]"]
  sf-deploy.ps1 -hp

OPTIONS:
  -to  Target org alias or username for --target-org
  -sr  Sources - comma-separated list of --source-dir paths
  -dr  Directory - single directory path to deploy (alternative to -sr)
  -ts  Tests - comma-separated list of --tests (enables --test-level RunSpecifiedTests)
  -hp  Help - show this help

EXAMPLES:
  1) Real deploy with multiple flexipages (specific files):
     sf-deploy.ps1 -to "DEMO-ORG" ``
       -sr "force-app/main/default/flexipages/Sample_Page.flexipage-meta.xml,force-app/main/default/flexipages/Sample_Page_Backup_With_SalesNavigator.flexipage-meta.xml,force-app/main/default/flexipages/Sample_Role_Record_Page.flexipage-meta.xml"

  2) Real deploy with entire directory:
     sf-deploy.ps1 -to "DEMO-ORG" -dr "force-app/main/default/classes"

  3) Real deploy with specified tests:
     sf-deploy.ps1 -to "DEMO-ORG" ``
       -sr "force-app/main/default/flexipages/Demo_Page.flexipage-meta.xml,force-app/main/default/flexipages/Demo_Page_Backup_With_SalesNavigator.flexipage-meta.xml" ``
       -ts "SelectorOpportunity_Test,SelectorOpportunity2_Test"

Notes:
- Use -sr for specific files (comma-separated) OR -dr for entire directories (not both).
- Pass absolute or repo-relative paths.
- Multiple tests are comma-separated in -ts; they will be expanded to multiple --tests flags.
