fix: add bash control structure keywords to sudo command processing

Browse source 
Fixes issue #7346 where proxy startup failed on non-root servers due to
bash syntax errors when control structure keywords like 'for', 'do', 'done',
'break', and 'continue' were being prefixed with 'sudo'.

Added comprehensive exclusion list including for/while/until/case/select
loops, conditionals (if/then/else/elif/fi), and loop control keywords
(break/continue). Also excludes comment lines starting with '#'.

All 37 unit tests pass, including new tests for each bash control structure.
