## Description
This PR fixes an issue where asset files copied during a build using the
`@nx/js:tsc` executor are placed in the wrong directory depending on the
current working directory from which the `nx` command is executed.
This behavior becomes particularly problematic in scenarios like release
workflows that rely on `preVersionCommand` to run E2E tests. For
instance, when using tools like Jest from the root of an E2E project,
scripts like `start-local-registry` may trigger a build and run the
`preVersionCommand`. However, instead of placing assets in the expected
`dist` folder of the project, they are incorrectly copied relative to
the E2E folder’s location.
## Reproduction Steps
1. Create a new Nx workspace:
```bash
npx --yes create-nx-workspace assets-issue --preset=ts --no-interactive
cd assets-issue
```
2. Add the Nx Plugin package:
```bash
nx add @nx/plugin
```
3. Generate a new plugin:
```bash
nx g @nx/plugin:plugin packages/my-plugin --linter eslint
--unitTestRunner jest
```
4. Add a generator to the plugin:
```bash
nx g @nx/plugin:generator packages/my-plugin/src/generators/my-generator
```
5. Build the plugin from the workspace root:
```bash
nx build my-plugin
```
✅ Assets are copied correctly:
```
dist/packages/my-plugin/generators/files/src/index.ts.template
dist/packages/my-plugin/generators/schema.json
dist/packages/my-plugin/generators/schema.d.ts
```
6. Now build the same project from a nested folder:
```bash
mkdir e2e && cd e2e
nx build my-plugin --skip-nx-cache
```
❌ Assets are copied relative to the current folder:
```
e2e/packages/my-plugin/dist/generators/files/src/index.ts.template
e2e/packages/my-plugin/dist/generators/schema.json
e2e/packages/my-plugin/dist/generators/schema.d.ts
```
## Expected Behavior
The build output—especially copied assets—should always respect the
project’s `outputPath` configuration regardless of where the `nx`
command is invoked from. The behavior should be consistent and **not
influenced by `process.cwd()`**.

## Current Behavior
<!-- This is the behavior we have today -->
CopyAssetsHandler was not outputting the assets in the correct location
due to issues with `path/posix`.
`path/posix` is required for some areas of this code, like `minimatch`.
## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
`minimatch` ignores should continue to work as expected
assets should be output to the correct location
