Search people on LinkedIn by job title(s), current company and location. Pass `company` (a NAME like 'Škoda Auto') to filter to people who CURRENTLY work there. For decision-maker discovery pass `titles` — an ORDERED priority list; the server tries them one at a time and stops at the first that returns anyone (one company + one matched role, minimal LinkedIn calls). Returns JSON `{ count, results, matched_title, tried_titles, company_filter }` where each item in `results` has: `linkedin_url`, `name`, `headline`, `company`, `location`, `public_id`, `network_distance` (read `linkedin_url` for the profile URL — NOT `profiles`/`url`). `matched_title` is the title that produced the hits; `company_filter.mode` is `current_company` when the name resolved to LinkedIn's native filter, or `keyword_fallback` when it could not. It does not save them as Salesbot contacts. For each profile you want to keep or add to a campaign, call upsert_linkedin_contact with its `linkedin_url` to obtain a contact_id. Pass either `location` (human name like 'Praha', 'Berlin', 'Czechia') or `locationId` (raw LinkedIn geo ID).
