Update a WebZum site's universal contact fields — phone, email, WhatsApp, the
primary contact channel, address, hours — OR the business/brand name. Use this
(NOT update_site_html) for these fields: it updates the canonical business record
AND sweeps every page, so contact-form delivery, tel:/mailto:/wa.me links, header,
footer, page titles, and body copy all stay in sync.
WhatsApp: pass an instruction like "add my WhatsApp +966 55 123 4567" (keep the
country code) to render a wa.me click-to-chat button site-wide, or "make WhatsApp
the main way to reach us" to set it as the primary CTA.
Required: businessId, versionId, and a conversationHistory containing at least one
user turn describing the change verbatim. Do NOT use for general copy/layout edits
(use update_site_html) — this tool only touches contact fields + the business name.
Returns { versionId, status: 'completed' | 'in_progress', ...extra }. If status is
'in_progress', poll get_site_status with the returned versionId every 5-10s until
isComplete is true.
Concurrency: edits on the same businessId MUST be serial.
