fix: harden low-confidence event dedupe

[chubes4]

Summary

• add generic event identity confidence heuristics in data-machine-events without hardcoding market, festival, or event-type assumptions
• prevent low-confidence titles from using aggressive exact/fuzzy upsert matching paths when venue/date context is weak
• add unit coverage for low/medium/high confidence title behavior and schedule-blob detection

Why

Austin/SXSW pressure exposed that the generic dedupe engine in core was receiving weak event identities from data-machine-events. This change hardens the event-domain matching layer so low-information titles are less likely to merge incorrectly, while still allowing stronger recurring/specific events to dedupe normally.
