A worker no longer reads German where the owner speaks English

GitHub issue #74: with English interface, English conversation and an English task, a worker wrote its status line in German (“Code gelesen, plane jetzt Schema und Auswahl pro Frage”). Its instructions said the owner's language is English, but German examples and quotation marks scattered through them suggested otherwise. Here is what the worker reads now.

1 · Passing a request on to Obeya (worker, idea agent, proposal reviser)

Before… a follow-up card, a rule to remember („Merk dir …“), grouping cards …
After… a follow-up card, a rule to remember, grouping cards …
Before… actions wait a few seconds for the owner's „Rückgängig“.
After… actions wait a few seconds for the owner's Undo.

2 · Quoted titles, options and replies

Everything Obeya quotes to a worker or an idea agent (picked options, card titles, the message a note replies to, places in the demo video, findings of a review) uses English quotation marks. Only the quotation marks change; the quoted words stay as the owner wrote them.

BeforeThey picked „CSV“.
AfterThey picked “CSV”.

What stays German, and how it is kept so

Obeya itself (the assistant that takes the owner's commands) keeps its German examples: it has to understand “Merk dir …” and “Rückgängig” when the owner says them.

A new test starts a worker for an English-speaking owner and checks that its instructions and every tool description hold no German letters, German quotation marks, “Merk dir” or “Rückgängig”. It fails on the code before the fix and passes now; the full test suite and type check pass.
