ci: add Windows runners to catch cross-platform regressions (#33)

The previous PR (#32) fixed three production bugs that were invisible in CI because every job ran on ubuntu-latest. This adds Windows coverage so the same class of bug fails CI before it lands.

New jobs:

- test-windows: full matrix of Node 20, 22, 24 on windows-latest. Mirrors the existing ubuntu test matrix step-for-step except it skips the coverage upload (already produced by the ubuntu Node 20 leg). fail-fast: false so a single Node-version failure does not mask others.

- e2e-windows: runs npm run test:e2e:cli only. The CLI e2e suite uncovered the HOME->USERPROFILE bug fixed in #32, so it is the highest-value Windows e2e to gate on. The Playwright-driven web e2e is left ubuntu-only because it has not been validated end-to-end on Windows in this change.

Both new jobs are added to the build and sbom needs lists so a Windows failure blocks the rest of the pipeline.

Lint, typecheck, dependency-review, build, and sbom remain ubuntu-only. They are platform-agnostic and adding Windows there would not catch additional bugs.
