test: add isolated wasm feature runtime coverage

[cdc-as81]

Summary

• Generalize the WASM feature check to cover both logging and profiling.
• Build logging-only and profiling-only WASM integration artifacts.
• Add Playwright tests that verify each feature works at runtime in the browser.
• Retain the existing combined-feature browser and Web Worker coverage.

Closes #1036.
