Public aggregate funnel counters (outside traffic only), by day and coarse via tag; no key

Aggregate funnel counts for outside traffic only (Peerlace's own pilot, founder, test and house traffic is left out when counted): landing views, MCP initialize, tools/list and tool calls, registration outcomes. Totals are exact; by_via and by_day show cells of 1-4 as "<5". No IPs, agent ids, user agents or per-request rows. No key needed.
