Create or revise a people-search Play and optionally run it

Find people from a targeting, the same way the PumpGTM agent does. Provide targeting (creates a Play, or revises playId at expectedRevision, the play.revision from the previous response), a playId alone (use the Play as is), or both. run: false (default) prepares and returns 200 with the targeting summary; run: true searches and returns 201 with the review batch and candidates. requestId is required when run is true: a run is billed, so a retry must carry the same requestId to replay the stored result (reused: true) instead of searching and charging again. sequenceId becomes the Play's default sequence (a draft is approved and started). A run crawls toward candidateCount, up to 100 people; each person found costs 2 Energy on metered workspaces (drawn from the partner pool for partner users) or, for partners without Energy, counts toward partner lead metering (50 free, then 403 billing_required with a checkout link in message). Finding people never contacts anyone. 409 targeting_needs_clarification with ambiguities when targeting is incomplete; company-name ambiguity never blocks (read companyResolution). 409 draft_changed when the Play changed since expectedRevision. 403 user_lead_cap_reached or billing_required for a partner user who may not search.
