process_line_runstream() chose between the stripped line and the raw buffer
on obj->mode == AKBASIC_MODE_REPL, but nothing reaches that function except
the RUNSTREAM arm of step(). The stripped branch was dead, so every program
the driver ran from a file was stored with its own line number inside
source[]: LIST printed "10 10 PRINT", and DSAVE and HELP would have echoed
it the same way.
No .bas in either corpus calls LIST, and runtime_verbs.c's load() helper --
which claims to load "the way RUNSTREAM would" -- already stored the scanned
line, so it encoded the correct contract and could not catch the wrong one.
The new test drives the real sink path instead.
Keep the step-over-a-leading-number allowance in scan_line_labels() and
skip_lineno(): no path inside the library stores a raw line now, but
akbasic_runtime_store_line() is public and a host may hand it one.
