Tachikoma 743e610f8f Reset scratch per line and unwind dead scopes in host function calls ...

akbasic_runtime_call_function()'s body loop drives process_line_run()
directly, skipping the per-line prologue akbasic_runtime_step() provides.
The call environment's value scratch therefore accumulated across the
whole body, and any body past about ten real lines died with 'Maximum
values per line reached' -- a limit that is supposed to be per line. The
loop now runs the same prologue step() does.

A body that died also left its call scopes active: nothing popped them,
so a host absorbing script errors drained the twelve-slot environment
pool after twelve dead calls. The loop now unwinds to the caller's
environment on every exit path.

New: akbasic_runtime_clear_error(), the missing half of host revival. A
run's first BASIC-level error latches deliberately, and set_mode(RUN)
alone cannot un-decide that; a host that absorbed the error calls this
beside it. Both defects and the revival dance are pinned in
tests/user_functions.c.
