Silisizer

Operator resize for meeting timing.

Run the timing optimizer from Tcl after loading and linking the design:

sta::silisize workdir

Pass -all to upsize every eligible offender found during each timing pass instead of using adaptive batch sizing:

sta::silisize -all workdir

Pass -wns to stop after three consecutive timing passes without WNS improvement, even if other violating paths could still improve:

sta::silisize -wns workdir

The policies can be combined:

sta::silisize -all -wns workdir

silisize always creates workdir/data/resized_cells.tsv (header only when no cells are resized) so Preqorsor can back-annotate SPEED==2 runs. Failure to create that file is a hard error.
