sf-deploy — wrapper for `sf project deploy start`

USAGE:
  sf-deploy -o <ORG_ALIAS_OR_USERNAME> (-s "<src1>,<src2>[,...]" | -d <DIRECTORY>) [-t "<Test1>,<Test2>[,...]"]

OPTIONS:
  -o  Org alias or username for --target-org
  -s  Comma-separated list of --source-dir paths
  -d  Single directory path to deploy (alternative to -s)
  -t  Comma-separated list of --tests (enables --test-level RunSpecifiedTests)
  -h  Show this help

EXAMPLES:
  1) Real deploy with multiple flexipages (specific files):
     sf-deploy -o DEMO-ORG \
       -s "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 -o DEMO-ORG -d "force-app/main/default/classes"

  3) Real deploy with specified tests:
     sf-deploy -o DEMO-ORG \
       -s "force-app/main/default/flexipages/Demo_Page.flexipage-meta.xml,force-app/main/default/flexipages/Demo_Page_Backup_With_SalesNavigator.flexipage-meta.xml" \
       -t "SelectorOpportunity_Test,SelectorOpportunity2_Test"

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