Fix critical IndentationError preventing script execution

[github-actions]

Problem

The script has a critical syntax error that prevents it from running at all:

IndentationError: expected an indented block after 'for' statement on line 940

This was introduced in a previous commit and completely blocks script execution.

Root Cause

Lines 938-940 in the validate_hostname() function contained unreachable dead code after a return False statement:

            return False

            if not addr_info:      # ← unreachable
                return False       # ← unreachable  
            for res in addr_info:  # ← empty for loop = syntax error

The empty for loop on line 940 triggers an IndentationError because Python expects an indented block after the for statement.

Solution

Goal and rationale: Fix the critical syntax error that prevents the script from running. This is a blocking bug that must be resolved immediately before any other work can proceed.

Approach: Remove the unreachable dead code (lines 938-940) that appears after a return False statement. This code was never executed and the empty for loop caused a syntax error.

Impact:

• Before: Script cannot run at all - immediate syntax error on import
• After: Script runs normally
• Files changed: main.py (removed 4 lines of unreachable code)

Validation:

• ✅ python3 -m py_compile main.py now passes (was failing before)
• ✅ Script can be imported without syntax errors
• ✅ No functional changes - only removed unreachable dead code

Future work: Once this is merged, the script will be functional again and other pending issues can be addressed. This unblocks:

• All test execution
• PR reviews that require running the code
• Any development work requiring script imports

This is a critical bugfix that unblocks all script functionality.

Pull request overview

This PR fixes a critical IndentationError that prevented the script from executing. The error was caused by dead code (lines 938-940) that was unreachable within the except block of the validate_hostname() function. These lines appeared after a return False statement and included an empty for loop, which Python flagged as a syntax error.

Changes:

• Removed 4 lines of unreachable dead code from validate_hostname() function
• Fixed IndentationError that prevented module import
• No functional changes (removed code was never executed)
