RELEASE:1.9.0

[gargsaumya]

AB#45750

Release mssql-python v1.9.0. Bumps __version__, setup.py version, and updates PyPI_Description.md with this release's customer-facing changes.

Summary

Enhancements

• Row Objects in Bulk Copy - bulkcopy now accepts Row objects (and lists) directly, converting each row to a tuple automatically (FEAT: Accept Row objects in bulkcopy without manual tuple conversion #615).
• Cached Parameter Type Resolution for NULLs - SQLDescribeParam results are cached per statement when binding NULL parameters, removing redundant server round-trips and fixing incorrect type fallbacks for all-NULL columns and VARBINARY types (FIX: Cache SQLDescribeParam results for NULL parameters to reduce server round-trips #614).

Bug Fixes

• macOS / Linux Import Failure - simdutf is now always statically linked via FetchContent, fixing import/symbol failures on machines without simdutf at the CI build path (FIX: always statically link simdutf via FetchContent #608). Resolves macOS wheel fails to import - simdutf symbols not found at runtime #607, mssql-python==1.8.0 fails with dlopen failed to resolve symbol. #628.
• executemany Large Decimal Handling - Fixed a SQL_C_NUMERIC type mismatch when inserting Decimal values outside the SQL Server MONEY range via executemany (FIX: executemany SQL_C_NUMERIC mismatch #611). Resolves mssql-python 1.7.1 and 1.8.0 both fail on executemany #609.
• Exception Pickling - DB-API exception subclasses and ConnectionStringParseError now implement __reduce__ for correct pickle/unpickle round-trips (FIX: exception pickle/unpickle round-trip #616). Resolves Exceptions do not properly pickle and unpickle #587.
• PRINT Messages in nextset() - Diagnostic messages from subsequent result sets are captured on SQL_SUCCESS_WITH_INFO during nextset() (FIX: Capture PRINT messages in nextset() via SQL_SUCCESS_WITH_INFO #618). Resolves mysql-python loses anything past the first message #612.
• Row Objects in executemany DAE Path - executemany converts Row objects to tuples in the DAE fallback path, fixing varchar(max) writes (FIX: Handle Row objects in executemany DAE fallback path (GH-629) #630). Resolves 1.8.0 fails in writing to varchar(max) #629.
• Static Type-Checking of Fetch Methods - fetchone/fetchmany/fetchall are no longer reassigned as instance attributes, fixing type-checking under ty (FIX: fetchone/fetchmany/fetchall type-checking under ty (#620) #631). Resolves cursor.fetchall, fetchmany and fetchone fail to type-check under ty #620.

Version bump

• mssql_python/__init__.py: __version__ 1.8.0 → 1.9.0
• setup.py: version 1.8.0 → 1.9.0
• PyPI_Description.md: updated "What's new" section to v1.9.0
