fix(typescript): resolve tsconfig paths aliases on Windows (#3203)
* fix(typescript): resolve tsconfig `paths` aliases on Windows

`rebaseTarget` turns a `paths` target that `path.resolve` produced back into
a repo-relative one, and it recognised the wildcard suffix only as `/*`. On
Windows the resolved target is `C:\repo\src\*`, so the check never matched,
the bare-`*` branch stripped the star, `path.relative` ate the trailing
backslash, and every alias target came back as `src*`. `substituteStar` then
built `srclib/date` from `@/lib/date`, nothing resolved, and every alias
import was dropped as external — no IMPORTS/CALLS edge for anything reached
through `@/`, so `impact` answered UNKNOWN for a repo's whole shared layer.

Normalise the separator before looking at the suffix. `tsconfig-index.test.ts`
already asserts the `src/*` shape and fails 4 of 13 cases on Windows without
this; it only ever ran on Ubuntu, so add it to the cross-platform lane.

* test(typescript): make `paths` rebasing assertable from any runner

`rebaseTarget` reads the platform separator, but the only suite covering it
builds real directories — so on Ubuntu it sees `/` whatever the code does with
`\`, and only the windows-latest lane can fail it. That is how an alias bug
affecting every Windows install reached a green CI in the first place.

Thread an injectable `pathApi` through `rebaseTarget` and `repoRelative` — the
seam `isInside` and the `\\?\` prefix guard already use — and add a
fixture-free suite that pins the win32 and POSIX branches explicitly. Deleting
the separator normalisation now fails on every runner rather than only on
windows-latest.

Registered beside its fixture sibling in the cross-platform lane so the two
halves of the same rule stay discoverable as one group.

* fix(typescript): emit a bare `*` for a repo-root `paths` target

A target naming the repo ROOT — `"*": ["./*"]` under `"baseUrl": "."` — rebases
to an EMPTY repo-relative prefix, so only the suffix survived and the encoding
came out as `/*`. `substituteStar` turns that into `/lib/date`, and
`resolveFile` matches repo-relative keys without stripping a leading slash, so
the indexed `lib/date.ts` misses and the alias is dropped as external.

Emit the bare `*` for that case instead, which substitutes to `lib/date` and
resolves. This is the shipped POSIX encoding as much as the Windows one, and it
is what the Windows path emitted by accident before the separator was
normalised — so the normalisation does not narrow what already resolved there.
The common `"@/*": ["./src/*"]` is untouched: it has a real prefix and stays
`src/*`.

Pinned at all three levels the encoding passes through: the rebaser, on both
path flavours; the loader, through a real fixture; and resolution, where `*`
finds the file and `/*` does not.

* docs(test): say why the root-wildcard fixture declares no `baseUrl`

The comment introduced the fixture as `"baseUrl": "."`, which the loader
encodes as `''`, while the fixture passes `null` — a different scope, since
`null` means the config declares no baseUrl at all and takes the paths arm
alone.

`null` is the right fixture and the comment was the wrong half: with `''` the
baseUrl arm resolves `packages/utils/src/index` by itself, so the negative case
would return null for a reason unrelated to the target encoding. Verified by
substitution — `''` makes that assertion report the file instead.
