Run build-test coverage on Windows

[timsehn]

Summary

• run Build-Test shell/C/testfixture coverage on the Windows matrix leg
• build Windows test dependencies: sqlite3, testfixture, and Python for analyzer-backed tests
• keep Linux-only Python LD_PRELOAD and Go integration steps on Ubuntu only

Validation

• ruby YAML parse for .github/workflows/build-test.yml
• git diff --check for .github/workflows/build-test.yml

File-Backed (autocommit)

Each statement runs as its own transaction — exposes per-commit
fixed costs that the wrapped-in-BEGIN/COMMIT tests amortize away.
SQLite uses WAL mode with synchronous=FULL in this section so
the comparison uses SQLite's durable WAL autocommit path.

Reads

Reads have no commit cost; these are the same SQL files as the
File-Backed Reads section, included here for symmetry and to
catch any per-statement overhead doltlite pays on the read path.

File-Backed (autocommit)

Each statement runs as its own transaction — exposes per-commit
fixed costs that the wrapped-in-BEGIN/COMMIT tests amortize away.
SQLite uses WAL mode with synchronous=FULL in this section so
the comparison uses SQLite's durable WAL autocommit path.

Reads

Reads have no commit cost; these are the same SQL files as the
File-Backed Reads section, included here for symmetry and to
catch any per-statement overhead doltlite pays on the read path.
