The StaConfig.hh is often included as bare file without the fully
qualified path.
If we provide it in a library, we can provide the `includes=[]`
for the header to be found.
(of course, we ideally want the proper fully qualified path, but
that takes a while until we're there).

Upstream e9c075ab (BIGFEATURE: Add `set_path_margin` command, parallaxsw#469)
added a `PathMargin *path_margin` parameter to the PathEndCheck,
PathEndOutputDelay and PathEndGatedClock constructors, between `mcp` and the
argument that followed it.
Our per-module gtests are not in the upstream tree, so the upstream change did
not touch them and the merge left them calling the old arity. Pass nullptr for
the new parameter; these cases only exercise type()/typeName()/copy(), so no
margin is needed.
No behavioral change - test-only API adaptation.

Update goldens for "dcalc no slew merge for constant disabled arcs".
dcalc_case_analysis_leak: arrival spread across the wire-load sweep on the
constant net drops from 46.38 ps to 0.00 ps, which is the point of the test.
Rewrite the header comment to describe the fix rather than the open bug.
graph_modify: with set_case_analysis 0 on d4, inv2 drives n4=1 and or1
drives n6=1, so nand1/A2 is constant. 1 is non-controlling for a NAND, so
nand1/ZN stays live and the A2->ZN arc is dead. Its slew no longer merges
into nand1/ZN, so buf4/Z falls from 0.07 to 0.06. The following report,
after unset_case_analysis, still shows 0.07 as expected.
sdc_port_delay_advanced: in1=0, in2=1 and case analysis 0 on in3 make
nor1/ZN constant, so it is no longer reported as the worst max slew pin;
reg1/QN takes its place.

* Implement set_path_margin command
Adds a new set_path_margin SDC command that applies a signed slack
adjustment to the capture-clock side of timing paths. A positive
margin tightens the path (harder to meet) and a negative margin
loosens it. Supports -setup/-hold/-from/-through/-to scoping,
priority/override semantics matching other exceptions, text and
JSON report output, and write_sdc serialisation.
Adapted from Silimate PR #57; uses upstream/master Mode/Scene and
string_view APIs. Test uses unset_path_exceptions in place of the
Silimate-only reset_path alias.

* Address review: store PathMargin on PathEnd, split tests
Keep the path margin exception on PathEndClkConstrained, add
PathEnd::hasPathMargin for report gating, and split the monolithic
regression into set_path_margin1–6. Rebased onto upstream/master and
document the command in ChangeLog.

Store max dynamic/leakage power like max area, expose getters through Sta,

* write_path_spice: match side input values to the path arc's transitions
gatePortValues() chose side input values from the first CUDD cube of the
Boolean difference d(f)/d(input), which sensitizes the gate but ignores
the transition directions of the arc the path used:
- For non-unate gates whose Boolean difference is a tautology (xor2,
xnor2) every side variable came back don't-care, and the unknown value
fell through to tie-low in writeSubcktInstVoltSrcs() -- wrong whenever
the path used the when-condition requiring the side high.
- For mux select arcs the cube was an arbitrary data assignment,
unrelated to the output edge the path reported.
Either way the written deck's gate drives the opposite direction from
the reported path: the simulated chain switches with inverted polarity
from that gate onward, edge-qualified arrival measurements fail, and
the deck sums delays from the wrong rise/fall tables.
Constrain the side input condition to the cofactor pair matching this
arc -- f1 & !f0 when the input and driver edges agree (non-inverting),
f0 & !f1 when they differ (inverting) -- threading the gate input
RiseFall from the path stage into gatePortValues(). Also release the
CUDD nodes that were previously leaked (the old code Cudd_Ref'd the
Boolean difference after the generator was freed and never deref'd it).

We used to use runfiles to work with tcl dependencies. Since we don't
need that anymore, just add a regular `BAZEL_BUILD` define to
choose the behavior in the bazel build and remove the unneeded
dependency.
