v1.5.0

WRITING.md now says how a text is made: a brief, an English draft on the branch, the owner's
review in the diff and on the rendered page, and German translated from the reviewed English
one element at a time, reviewed by reading the translator's back-translation. The Languages
paragraph says the German is that translation, made for a reader in Zürich or Bern and Swiss
in its forms. The prose register says what separates a page from a README.

Three files join conventions/: WRITER.md and TRANSLATOR.md, the two roles that make a text,
and GLOSSARY.md, every family term in its fixed English and German form. WORKING.md says a
role invoked as a subagent edits and reports and never commits.

Nothing breaks. To take it, move both tags to v1.5.0, run sh conventions/conventions-sync
sync once, and add .claude/agents/writer.md and .claude/agents/translator.md from the README
recipe.
