Wire: faster search, cleaner discovery

Token discovery got significantly faster and significantly cleaner.

Token queries that previously took seconds now return in under 100ms. Filterable fields are maintained in a dedicated search index that updates as tokens trade — no computation on query.

Dead token filtering is on by default. Tokens with no recent trading activity, or tokens that have crashed more than 90% from ATH with no recovery, are excluded from discovery results. /discover bypasses this for the unfiltered feed.

Covered edge case scenarios for inactive tokens — volume windows now zero out automatically when a token stops trading.
