Bug: low/normal trigger command environments are built from trigger_cmd_high

[somethingwithproof]

Summary

In thold_command_execution(), the environment for trigger_cmd_low and trigger_cmd_norm branches is built using trigger_cmd_high.

Impact

• Variable extraction/context can be inconsistent with the command actually executed.
• Low and normal-restoral command paths may receive incorrect environment substitutions.

Location

• thold_functions.php, function thold_command_execution()
  • breach-down path uses thold_set_environ($thold_data['trigger_cmd_high'], ...)
  • breach-normal path uses thold_set_environ($thold_data['trigger_cmd_high'], ...)

Expected

• breach-up uses trigger_cmd_high
• breach-down uses trigger_cmd_low
• breach-normal uses trigger_cmd_norm
