Support for std::{from,to}_chars isn't finalized in
libcxx as of the time of writing, see __cpp_lib_to_chars in
6331bfa41a/libcxx/docs/FeatureTestMacroTable.rst
This patch adds a fallback using strtof. There are two
differences:
* strtof is locale-dependent
* strtof tolerates leading spaces

* Provide close2proc function to prevent tcl9 from crashing.
Tcl 9 does not test if the close2Proc function pointer is non-null,
but calls it unconditionally:
https://github.com/tcltk/tcl/blob/core-9-0-3/generic/tclIO.c#L384
So we need to provide a non-null function pointer for our code
to not crash with Tcl9.
Use the same implementation as the previous close channel
had.

* Use non-deprecated trace add variable syntax.
In modern tcl, `trace variable` is now i`trace add variable`,
and `"rw"` should be spelled out as `{read write}`
There were backwards compatible forms in Tcl 8.x but now loudly
complains in Tcl 9

* Use `Tcl_Size` for all tcl functions returning sizes.
This is the type the Tcl-API provides in its prototypes and
starting from Tcl9 this typedef actually changes from `int` to `long`,
so will no longer compile when passing an `int*`.
So whenever we get a return value of this type, use the
correct typedef to declare the variable. This makes it forward and
backward compatible.

* Address review comments: compare with `read`/`write` not `r`, `w`

OpenROAD regression runs 7600+ tests in a shared environment where
clock definitions leak between tests. Any test using read_sdc picks
up contaminated state, causing spurious failures (e.g., clk2 period
15 vs 20). Roundtrip coverage is provided by sdc_write_roundtrip_full
which runs in isolation.
Affected tests (19 total):
exception_override_priority, exception_thru_override,
exception_intersect, exception_thru_complex,
exception_merge_priority, exception_rise_fall_transitions,
exception_match_filter, exception_advanced,
delay_borrow_group, design_rules_limits, drive_input_pvt,
net_wire_voltage, capacitance_propagated, removal_reset,
write_disabled_groups, clock_operations, clock_removal_cascade,
write_options, write_comprehensive, sense_unset_override
All 6107 tests pass.

The read_sdc roundtrip section fails in OpenROAD regression because
the shared test environment leaks clock definitions from other tests
(clk2 period 15 vs 20). Roundtrip coverage is already provided by
sdc_write_roundtrip_full which runs in an isolated context.

Upstream added bias pin type recognition, changing VNB/VPB pin
direction from "unknown" to "bias" in liberty output. Update 9
golden .ok files to match.

- Use diff_files_sorted for exception_override_priority SDC comparisons
to handle non-deterministic write_sdc output ordering across environments
- Add (VERSION ignore pattern to SDF diff_files calls so tests don't
break on upstream version bumps

Add (VERSION pattern to diff_files ignore parameter so SDF tests
don't break on every upstream version bump. Update golden .ok files
to reflect the now-clean diffs.
