find_end_subshell_before_cur_pos() now accounts for offset caused by
two-character tokens (|| and &&).
Added many explanatory comments.
Modified or removed some fields of the params structure that affected pipe and
subshell behavior (e.g., pgid for multiple processes, file descriptors).
Changed logic for setting the current terminal process group.
Removed side effect in the conditional operator inside special_token_handling()
that made the code harder to read.
Removed the functions identify_general_pgid() and identify_general_pipe_pgid().
Replaced them with a single function: set_foreground_group().
make_pipeline() now also checks for subshell_before before executing the
pipeline.
Major changes to the functions make_pipeline(), make_subshell(), and
run_external_program().
Subshell exit code now depends on the success or failure of executed programs
when using logical operators (|| and &&).
