v7.6.5

• Tweak - Partner attribution (the /p/ partner links, attribution cookie, co-brand banner and hand-off capture into DEFHO) has moved out of Digital Employees into the Widrow Attribution companion plugin, which the Widrow pitch sites install alongside it. Every other site is unaffected: nothing about the chat, the hand-off form or the email changes.
• Feature - Two extension points for site companions: the def_core_customer_chat_handoff_body filter (the hand-off email body, with the allowlisted fields and the raw request) and the def_core_page_context filter (the page context the chat sends with every message; a partner key is forwarded to DEF).
• Tweak - Security hardening: the page-context payload written into the page's inline script is now HTML-safe (JSON_HEX_TAG), so no value on it can break out of the script tag.
