ci: run the full unit suite on windows (#5370)

* ci: run the full unit suite on windows via make unit

Drops the curated `unit:windows` subset; the windows job now bootstraps like linux and runs `make unit`. Exceptions get added as failures show up.

* ci: skip fixture refresh for windows unit tests

binny has no windows release, so the bootstrap action can't install the tools the fixture refresh needs.

* test: skip linux container fixtures when docker can't run them

Windows CI runners only run windows containers, so image fixtures go through `testutils.SkipWithoutLinuxContainers`. No behavior change on linux/mac.

* fix: close leaked file handles and posix squashfs paths on windows

- output writers are now closed on early returns in `scan`/`convert` (open handles block cleanup on windows)
- `newSBOMMultiWriter` used `path.Dir` on host paths, so output subdirectories were never created on windows
- squashfs walk paths were built with `filepath.Join`
- skip a few posix-only test cases (dir perms, xdg fallback, go-rpmdb ndb handle leak upstream)

* fix(golang): resolve go source module dir natively on windows

- `parseGoModFile` passed the resolver's posix (`/c/...`) path to the go toolchain, so go source resolution silently found nothing on windows
- skip container-built fixtures (go archs, java builds) and golden image tarballs on windows; stereoscope's layer cache filenames contain `:`, which windows rejects

* fix: keep posix paths posix on windows

- `ChrootContext.ToChrootPath` nested volumes (`D:\cwd\C:\root`) when the scan root was on another drive, so the prefix was never trimmed
- bitnami, python wheel/egg, and alpm parsers used `filepath` on posix location paths
- alpm backup-file lookups silently missed on windows

* ci: pull the test fixture cache for windows unit tests

* fix: don't map virtual file tree paths through the host on windows

`FiletreeResolver` without a chroot (snaps) ran request paths through `filepath.Abs`, rooting them on the current volume (`/payload.txt` -> `/d/payload.txt`), so snap scans on windows found nothing.

* fix: match tar entry globs as posix on windows

- `matchesAnyGlob` used `doublestar.PathMatch` (host separator) on tar entry names, so tar-wrapped java archives silently produced nothing on windows
- test helpers now treat binary snippet keys and `FromFile` locations as posix

* incorporate windows path fix

* incorporate go-rpmdb close fix

* close squashfs fixture writers before finalizing

- windows dir listings can report a zero size for files still open, so the manifest was packed empty

(also adds a temporary windows diagnostic for the binary cataloger)

* temp: surface windows binary cataloger diagnostics

* fix: keep directory symlink targets posix on windows

- the directory indexer joined symlink targets with native separators, so links in the posix file tree pointed nowhere and globs on link names found nothing
- binary fixture logical keys used native separators, so nested snippets were picked as the fixture dir on windows

* keep addSymlinkToIndex under the funlen limit
