Problem

The terragrunt module has inconsistent function naming:

• Stack commands: TgStackGenerate, TgStackRun, TgStackClean
• Init command: TgInit
• Run-all commands: ApplyAll, DestroyAll, PlanAllExitCode (missing Tg prefix)

This inconsistency is confusing and makes the API less discoverable.

Proposal

Rename run-all functions to use the Tg prefix:

• ApplyAll → TgApplyAll
• ApplyAllE → TgApplyAllE
• DestroyAll → TgDestroyAll
• DestroyAllE → TgDestroyAllE
• PlanAllExitCode → TgPlanAllExitCode
• PlanAllExitCodeE → TgPlanAllExitCodeE

Keep old function names as deprecated aliases for backward compatibility:

// Deprecated: Use TgApplyAll instead.
func ApplyAll(t testing.TestingT, options *Options) string {
    return TgApplyAll(t, options)
}

Benefits

• Consistent naming across all terragrunt module functions
• Better API discoverability
• Clearer distinction from terraform module functions
• Easier to identify terragrunt-specific functions in code

Breaking Change

This would be a breaking change requiring a major version bump. The deprecation period would give users time to migrate.
