test(ts-plugin): split completion and code-fix e2e tests into per-behavior cases

[mizdra]

Summary

Refactor packages/ts-plugin/e2e-test/feature/completion.test.ts and packages/ts-plugin/e2e-test/feature/code-fix.test.ts so that each test block owns a minimal fixture and asserts a single behavior, organized by the .d.ts/mapping pattern under test.

This is the 3rd PR of a multi-PR series (see #378 for the first PR / overall context, #379 for the previous PR).

What's new

• packages/ts-plugin/e2e-test/feature/completion.test.ts: rewritten as 11 behavior-focused tests organized into 3 describe blocks, each with its own minimal fixture.
• packages/ts-plugin/e2e-test/feature/code-fix.test.ts: rewritten as 11 behavior-focused tests organized into 3 describe blocks, each with its own minimal fixture.
• Added negative-side coverage for the namedExports: true && !prioritizeNamedImports branches:
  • completion: named tokens are filtered out of suggestions
  • code-fix: named import code fixes are excluded
• The two prioritizeNamedImports cases (on/off) are now siblings under a single parent describe so the pair is visually adjacent.

Test structure

completion.test.ts:

namedExports: $namedExports
├── styles binding suggestion (2 tests)
│   ├── prioritizes the CSS module corresponding to the current component file
│   └── inserts the import statement when accepted
└── className attribute snippet (2 tests via test.each)
    ├── quotePreference: single
    └── quotePreference: double

named token completion (namedExports: true)
├── prioritizeNamedImports: false (1 test)
│   └── omits named tokens from suggestions
└── prioritizeNamedImports: true (2 tests)
    ├── omits the default styles binding from suggestions
    └── suggests named token bindings

code-fix.test.ts:

namedExports: $namedExports
├── fixMissingCSSRule (2 tests)
│   ├── inserts a new CSS rule into an empty CSS module
│   └── appends a new CSS rule to a non-empty CSS module
└── auto-import (2 tests)
    ├── inserts the import statement when accepted
    └── excludes generated files from suggestions

named import code fix (namedExports: true)
├── prioritizeNamedImports: false (1 test)
│   └── omits the named import code fix
└── prioritizeNamedImports: true (2 tests)
    ├── omits the default styles binding code fix
    └── suggests a named import code fix

Total: 11 tests (completion) + 11 tests (code-fix) = 22 tests.

Test plan

• vp test --project e2e packages/ts-plugin/e2e-test/feature/completion.test.ts packages/ts-plugin/e2e-test/feature/code-fix.test.ts — 22 passed
• vp test --project e2e (full e2e suite) — no regressions
• vp check (format + lint + type) — pass
