/api/brands/search-watch

// /api/brands/search-watch — weekly search checks for saved brands (beta).
//
//   GET ?domain=              one brand's check, or all of the account's (read_reports)
//   POST { domain, action }   start | pause | resume | stop one brand's check;
//                             start also sends the market and max_cost_usd from
//                             the live quote the owner saw
//
// Each weekly check reads the provider's free Google data date and buys a
// search snapshot only when it is newer than the brand's latest one. Changing a
// check needs a browser session or an API key with run_pulls; assistant
// connections are read-only. See lib/search-watches.mjs.
