test(ts-plugin): split find-all-references and rename-symbol e2e tests into per-behavior cases

[mizdra]

Summary

Continue the e2e test refactor started in #378. Each test now owns a minimal fixture and asserts a single behavior, organized by the .d.ts/mapping pattern under test. This PR also revisits go-to-definition.test.ts so all three feature test files share the same describe structure.

This is the second PR of a multi-PR series (see #378 for the first PR / overall context).

What's new

• packages/ts-plugin/e2e-test/feature/find-all-references.test.ts: rewritten as 11 behavior-focused tests organized into 5 describe blocks, each with its own minimal fixture (was 17 cases sharing one fixture in a single test.each).
• packages/ts-plugin/e2e-test/feature/rename-symbol.test.ts: rewritten as 10 behavior-focused tests organized into 4 describe blocks, each with its own minimal fixture (was 13 cases sharing one fixture in a single test.each). Now also covers namedExports: true via describe.each (previously only namedExports: false).
• packages/ts-plugin/e2e-test/feature/go-to-definition.test.ts (existing from refactor(ts-plugin): split go-to-definition e2e tests into per-behavior cases #378): renamed a_alias to b_alias so the alias name reflects its source token, and added a new "CSS-side class declaration" test so all three files share the same group structure.

Shared describe structure

All three files share the same group layout (group 1 differs by feature):

namedExports: $namedExports
├── (group 1: feature-specific Volar.js auto-mapping)
│   - go-to-definition:   jumps to the top of a CSS module file (5 tests)
│   - find-all-references: finds all references to the styles binding (1 test)
│   - rename-symbol:       — (no equivalent: module specifier rename is
│                            `sendGetEditsForFileRename` territory and styles
│                            binding rename is core TS behavior)
├── <feature> a local token (TS-side trigger, 3 tests)
│   ├── from styles.<token> access
│   ├── from styles[<kebab-case token>] access
│   └── returns all declarations when the same class is declared multiple times
├── transitively resolves a re-export to its source declaration (3 tests)
│   ├── class re-exported via @import
│   ├── value re-exported via @value ... from
│   └── aliased value re-exported via @value ... from
├── <feature> from a CSS-side class declaration (1 test, newly added)
│   └── from a .<token> declaration
└── <feature> from a CSS-side @value ... from binding (3 tests)
    ├── from the import binding
    ├── from the alias name in `name as alias`
    └── from the source name in `name as alias`

Per-file totals:

• go-to-definition: 15 tests × 2 variants = 30
• find-all-references: 11 tests × 2 variants = 22
• rename-symbol: 10 tests × 2 variants = 20

Test plan

• vp test --project e2e packages/ts-plugin/e2e-test/feature/find-all-references.test.ts — 22 passed
• vp test --project e2e packages/ts-plugin/e2e-test/feature/rename-symbol.test.ts — 20 passed
• vp test --project e2e packages/ts-plugin/e2e-test/feature/go-to-definition.test.ts — 30 passed
• vp test --project e2e (full e2e suite) — no regressions
• vp check (format + lint + type) — pass
