fix(editor): reset compilation console filter on each new compile

The console auto-switched to the 'errors' filter when a compile produced
an error, but never reset it. After one failing compile, every later
SUCCESSFUL compile (info/success lines only) was hidden by the sticky
filter — the console looked empty while the simulation started, 'unless
there was an error'. Now reset the filter to 'all' whenever the log
shrinks (a fresh compile cleared it) so the next batch is always visible.
