docs: narrow delay-ms text entry guidance

[thymikee]

Summary

Clarifies that plain fill/type should be used first for ordinary login and form fields, and reserves --delay-ms for observed dropped-character or incremental-update cases.

Updates both versioned CLI workflow help and website command docs, with a focused help assertion to keep the guidance narrow.

Touched files: 3.

Validation

• pnpm exec vitest run src/utils/tests/args.test.ts
• pnpm format
• git diff --check

Docs/help-only change; no device verification needed.
