`Copy Error` and `Copy Test Errors` appear on non-Vitest test results

[alexchexes]

Describe the bug

Copy Error / Copy Test Errors actions appear on non-Vitest test results.

Clicking them on another controller's results is a no-op or can show unrelated Vitest warnings.

Vitest-specific copy actions seem to leak into foreign Testing controllers/results.

Expected behavior

Those actions should only appear for Vitest-owned results/messages.

Likely fix: add proper when scoping to the result/message menu contributions.

Reproduction

1. Install Vitest VS Code extension and another Testing extension, for cleaner repro I use AlexChexes.tmgrammar-test-tools-vscode which works on unsaved files.
2. Open a new VS Code window without any Vitest project or test files.
3. Open a new tab with a trivial test, for example:

// SYNTAX TEST "source.js"
foo = 42
//    ^^ constant.numeric.decimal.js

4. Run the test from the non-Vitest extension.
5. Open the Test Results view.
6. Observe that Vitest adds Copy Error / Copy Test Errors to foreign result/message items.

Output

No Vitest Output channel was created in this reproduction.
The issue reproduces in a new no-workspace window before any Vitest project/runtime is active.

Extension Version

1.50.1

Vitest Version
