JayPankajPatel 88fa9bb0a4 Fix bit_width calculation for ascending bus ranges in writeBusDcls 
std::abs(from - to + 1) gives the wrong result when from < to
(ascending ranges, e.g. [0:10]): abs(0 - 10 + 1) = 9 instead of 11.

Moving +1 outside abs fixes both ascending and descending ranges:
  ascending  [0:10]:  abs(0  - 10) + 1 = 11 (correct)
  descending [10:0]:  abs(10 - 0)  + 1 = 11 (correct)

Fixes #360

Jaehyun Kim 52887aa6db Regolden test golden files to fix false diff_files mismatches 
Update .libok/.txtok/.sdcok golden files to match current writer
output so diff_files produces "No differences found" instead of
silently reporting mismatches that were captured as expected output.

Jaehyun Kim 3ca78b11c8 Adapt test files to upstream API changes (string_view migration) 
Update 16 test files to match upstream OpenSTA API refactoring:
- const char* → std::string/std::string_view across all test APIs
- EXPECT_STREQ → EXPECT_EQ for std::string/string_view returns
- nullptr → "" for string_view parameters (makeClock, makeClockGroups, etc.)
- PropertyValue("literal") → PropertyValue(std::string("literal")) to avoid
  bool constructor overload resolution
- Method renames: relatedGroundPin→relatedGroundPort,
  relatedPowerPin→relatedPowerPort, firstName→firstParam,
  secondName→secondParam
- Constructor changes: OperatingConditions (5-arg → 1-arg + setters),
  ModeDef::defineValue (3-arg → 1-arg + setSdfCond)
- LibertyAttrValue::floatValue returns std::pair<float,bool> now
- Filter API: separate args → single expression string + bool_props_as_int
- SDF version golden files: 3.0.1 → 3.1.0

All 6104 tests pass.
