Subject: [PATCH] Enforce British English spelling in all agent prompt
 templates

Added explicit UK English instruction to the Response Format section of
all five agents (legal, brand, channel best practices, channel tech specs,
lead) so output uses spellings like "authorised", "colour", "capitalise".
