@lunora/cli

Diagnoses and fixes Lunora performance problems — full-table scans and missing indexes, expensive `ctx.db.related` traversals, OCC write conflicts (409 `CONFLICT`), live queries that re-run too often, hot shards, and choosing `.shardBy(key)` or `.global()` to scale. Starts from measured signal (`lunora insights`) and static signal (`lunora advisor`, `@lunora/advisor` lints such as `filter_without_index`, `unbounded_collect`, `unindexed_foreign_key`, `hot_shard`). Use when the user says a query or page is slow, mutations fail with conflicts under load, subscriptions are chatty, asks to "audit performance", "add the right index", or "should I shard this table", or when the Studio Advisors tab or `lunora advisor` flags something.
