Catch and Report Any Task

Write void catchAndReport(void (*task)(), const std::string& label), a safety net around a function it knows nothing about. It calls task() inside a try block and prints exactly one line:

- when the task finishes normally: the label, then : ok - when the task throws anything derived from std::exception: the label, then : failed (, what() and ) - when the task throws anything else: the label, then : failed (unknown error)

No exception may escape catchAndReport. The tests define a few tasks of their own (one prints and returns, one throws a std::runtime_error, one throws a plain int, one throws a std::logic_error), call catchAndReport for each with a label, and print all tasks reported at the end.

Do NOT write a main function.

Expected Output:

copying files↵
backup: ok↵
upload: failed (no connection)↵
cleanup: failed (unknown error)↵
verify: failed (checksum mismatch)↵
all tasks reported↵

= newline. The output ends with a newline — print one after the last line.
