junyao 46f9f887f7 setundef: strip init attributes from undriven wires (fixes #5835) 
When `setundef -undriven` connects an undriven wire to a replacement
value, the wire's \\init attribute (if present) is now removed. Previously,
the init attribute was left intact, causing downstream passes like
opt_merge to report "Conflicting init values" errors because the init
value contradicted the newly assigned constant.

For wires that are entirely undriven, the init attribute is removed
completely. For partially undriven wires (where only some bits are
undriven), only the corresponding init bits are cleared to x.

Wires driven by flip-flops or other cells are not affected, as they
are excluded from the undriven signal set before this code runs.

abhinavputhran 94c789e9c8 setundef: respect selection for cells, processes, and connections 
Previously, setundef would rewrite sigspecs in all cells, processes,
and connections regardless of the active selection. Only modules and
memories were correctly filtered by selection.

Fix by using module->selected_cells() for cells, adding a
module->selected() check for processes, and checking wire selection
on the lhs of each connection before rewriting.

Fixes #5624

Robert O'Callahan 37347aacb2 Check for missing port in SDC code 
I am getting weird crashes on `main` in `tests/sdc/alu_sub.ys` which I traced to a null `Wire*`
in `SdcObjects::constrained_ports`. The null `Wire*` is being set in the `SdcObjects`
constructor. I don't understand what's going on here, so I added this check to detect the
missing wire early ... and that made the crash go away. Compiler bug maybe? I have
`Debian clang version 19.1.7 (3+build5)`, default build configuration.

Anyway this code seems fine to have.

Robert O'Callahan 48cdb499f2 Remove `IdString::id_string()`. 
This was needed for the short time when `ID()` could return a value of `StaticIdString`.
That is no longer a problem.

Robert O'Callahan 46cb05c471 Pass IdString by value instead of by const reference. 
When IdString refcounting was expensive, it made sense to pass it by const reference
instead of by value, to avoid refcount churn. Now that IdString is not refcounted,
it's slightly more efficient to pass it by value.

I guess Tcl 9 broke this.
