What this PR does

Before this PR:
The Claude translator workflow had ambiguous skip conditions. For example, it didn't explicitly state when to skip already-translated or already-English content, and the catch-all rule was vaguely worded as "doesn't need any processing."

After this PR:
The translator workflow now has clearer, more explicit logic:

• Explicitly skips when translated content already matches the original.
• Explicitly skips when the content is already in English.
• The catch-all rule now reads "doesn't match any of the above cases, skip the task."
• Consistent punctuation (semicolons) across all rule items.

Why we need it and why it was done in this way

We noticed that the translator workflow would sometimes unnecessarily re-translate content that was already in English. The root cause was ambiguous skip conditions in the prompt — the workflow lacked an explicit instruction to skip when the content is already English, causing Claude to "translate" English into English redundantly.

This PR makes all skip conditions explicit to prevent such unnecessary translations and reduce wasted API calls.

Special notes for your reviewer

This is a prompt-level change only — no code logic is affected. The workflow behavior should be functionally equivalent but with clearer instructions for the Claude model.
