Add `pipe queries`, which lists every Firestore query a project can issue:
scope, collection, path pattern, filters with operators and value types,
composites, orderBy, limit, cursors, realtime, aggregation, in-loop, plus a
confidence and the reasons it is not exact. Receivers are matched by static
type and cloud_firestore library URI, never by name.
Queries are followed through chains, local variables (flow-insensitive with
two cuts), fields, getters and one level of helper methods with arguments
bound. An --adapter-config (YAML or JSON) maps declarative query APIs such as
a server-side gateway onto the same schema.
Inventory only: no rules, findings or baseline changes. Every emitted name is
validated against a safe character set so no source text reaches the output.
