Qwiratry::Aggregate::Rank

`class Rank`

aggsub Rank[Int, Int]() :!aggreduce { … }

Postgres RANK(): rank with gaps = 1-based index of the first row of the peer group (Aggregate Functions Plan §E.2). Peers are eqv on the call’s sort keys (AF-Q14). $.counter is the 1-based window index set by the Driver. Read path is $.frame-state via CALL-ME when $.frame-mode.

Rank.() takes no extractor (allows-zero-arg). Not usable in aggreduce (:!aggreduce). Peer logic lives in FRAMEADD (Match.Str compile path preserves .() Block calls; row DEPARSE would turn $.sort.($x) into accessor $.sort($x)). Row delegates to frame-enter.

Qwiratry v0.11.0

Declarative query and data-walking architecture for Raku, with transformers, molds, walkers, I/O pipelines, and aggregate functions.
