fix(setup): clear output buffer when switching contests

Browse source 
Problem: `setup_problem` only cleared the output buffer when
`old_problem_id ~= problem_id`. If two different contests both had a
problem with the same ID (e.g. `a`), the condition was false and stale
output from the previous contest remained visible.

Solution: clear the output buffer at the top of `proceed()` whenever
`is_new_contest` is true, before any problem setup runs.
