refactor(fix): rename test files to match naming convention

- Rename cmd-fix.test.mts → cmd-fix.integration.test.mts
  - File contains integration tests that spawn CLI process
- Rename cmd-fix-e2e.test.mts → cmd-fix.e2e.test.mts
  - Use dot notation for consistency with .integration pattern
- Update vitest.e2e.config.mts include pattern to match *.e2e.test.mts
- Update vitest.config.mts exclude pattern to match *.e2e.test.mts
