Update CLAUDE.md to reflect grouped attribute arrays in TestoClasses

Matches refactor from 75a5fcc: attributes are now organized into
TEST_ATTRIBUTES, TEST_INLINE_ATTRIBUTES, DATA_ATTRIBUTES, BENCH_ATTRIBUTES
arrays and spread across the codebase instead of being duplicated.

+### Testo PHP Framework — Supported Attributes
+
+The plugin recognizes PHP attributes defined in `TestoClasses.kt`. Constants are grouped into arrays for reuse across the codebase:
+
+| Group (array)          | Attributes (FQN)                                                                                      |
+|------------------------|-------------------------------------------------------------------------------------------------------|
+| `TEST_ATTRIBUTES`      | `\Testo\Attribute\Test` (new), `\Testo\Application\Attribute\Test` (old)                             |
+| `TEST_INLINE_ATTRIBUTES` | `\Testo\Sample\TestInline` (old), `\Testo\Inline\TestInline` (new)                                 |
+| `DATA_ATTRIBUTES`      | `\Testo\Sample\DataProvider`, `\Testo\Data\DataProvider`, `\Testo\Sample\DataSet`, `\Testo\Data\DataSet`, `\Testo\Data\DataUnion`, `\Testo\Data\DataCross`, `\Testo\Data\DataZip` |
+| `BENCH_ATTRIBUTES`     | `\Testo\Bench\BenchWith`                                                                              |
+
+Other constants: `ASSERT` (`\Testo\Assert`), `EXPECT` (`\Testo\Expect`), `ASSERTION_EXCEPTION`.
+
+These arrays are spread into `RUNNABLE_ATTRIBUTES` (line markers) and `MEANINGFUL_ATTRIBUTES` (PsiUtil) — adding a new attribute to the group array automatically propagates it everywhere.
 
 ### Test Detection Logic (mixin.kt)
 
 A PHP element is recognized as a Testo test when:
-- **Method:** public + name starts with `test`, OR has `#[Test]` / `#[TestInline]` attribute
-- **Function:** has `#[Test]` / `#[TestInline]` attribute (standalone test functions)
-- **Benchmark:** has `#[BenchWith]` attribute
+- **Method:** public + name starts with `test`, OR has any `TEST_ATTRIBUTES` / `TEST_INLINE_ATTRIBUTES`
+- **Function:** has any `TEST_ATTRIBUTES` / `TEST_INLINE_ATTRIBUTES` (standalone test functions)
+- **Benchmark:** has any `BENCH_ATTRIBUTES`
 - **Class:** name ends with `Test` or `TestBase`, OR contains test/bench methods
 - **File:** filename matches test class pattern, OR contains test classes/functions/benchmarks
