feat(prometheus): add clickhouseprometheusv2 native read path

Second-generation ClickHouse-backed Prometheus provider: the stock engine
evaluates over a native storage.Querier instead of the v1 remote-read
adapter. Per-selector fetch windows, last-sample-per-step reduction for
subquery-free instant selectors (gated on prometheus.QueryTraits),
identical-labelset merge, per-type __name__ matchers and anchored regexes,
inclusive series-lookup bounds for the exporter's hour-floored registration
rows.

Not wired: no factory registration, no config selection, nothing serves
from this package yet. Fetch budgets (series/sample ceilings) are
deliberately left out for now and will come separately.

+// Package clickhouseprometheusv2 is the second-generation ClickHouse-backed
+// Prometheus provider. It exists because the v1 provider fetches every raw
+// sample of a query's union window through the remote-read protobuf layer
+// and hands it to the engine — the cost is a function of ingested data, not
+// of the question asked. Here the stock promql engine evaluates over a
+// native storage.Querier: no translation layer, per-selector fetch windows,
+// and fetch reductions that are provably invisible to the engine. Every
+// reduction either preserves engine semantics exactly or is not performed.
+//
+// # Series lookup
+//
+// Matchers resolve to series once per selector (selectSeries) against the
+// time-series tables, which hold one row per (fingerprint, bucket) at
+// 1h/6h/1d/1w granularities; timeSeriesTableFor picks the table whose bucket
+// fits the window and rounds the window start down to the bucket boundary.
+// How matchers become SQL, and why regexes are anchored, is documented at
+// applySeriesConditions. Empty-valued labels come off at this boundary: an
+// empty value means "label absent" in Prometheus, but stored attribute JSON
+// can carry them.
+//
+// # Sample fetch
+//
+// Samples are fetched per selector using the engine's per-selector hints,
+// not the query-wide union window, so foo / foo offset 1d reads two narrow
+// windows instead of the widest one twice. Instant selectors of
+// subquery-free queries fetch only the last sample per step bucket — see
+// lastSamplePerStep for the correctness argument — while range selectors
+// always fetch raw: every sample feeds the range function. Row assembly maps
+// stale flags to the engine's StaleNaN and merges series with identical
+// label sets (sortAndMerge), because the engine assumes storages never emit
+// duplicates.
+//
+// # Sharding
+//
+// samples_v4 and time_series_v4 (and all their rollups) shard on the same
+// key — cityHash64(env, temporality, metric_name, fingerprint) — so a
+// series' samples and catalog rows live on the same shard. The samples
+// fetch exploits that: it restricts by a shard-local series subquery, not a
+// GLOBAL broadcast of the matched set. Delta-temporality
+// series stay invisible to PromQL exactly as they are in v1: the rollout
+// gate is parity with v1, and a Delta stream fed to rate() as-if-cumulative
+// would be wrong, not just new.
+//
+// # Observability
+//
+// Every statement carries a log_comment with
+// code.namespace=clickhouse-prometheus-v2 and code.function.name naming the
+// call site, so this provider's work is attributable in system.query_log.

+Upstream promqltest conformance: replay the frozen corpus extracted from

+
+Unlike the parity suites, the oracle here is a committed file
+(tests/integration/testdata/promqltestcorpus/corpus.json), generated by
+scripts/promqltestcorpus from upstream's load scripts and the vendored
+reference engine. It therefore keeps working when the serving path itself is
+the thing being changed — the one situation where comparing two live paths
+against each other is blind.
+
+Datasets are placed on disjoint time windows (2h isolation gaps, far beyond
+the 5m lookback) so one bulk ingest serves every case without cross-talk.
+Expected values carry the API's 3-significant-decimal rounding, mirrored by
+the generator; comparison allows one rounding quantum for ULP-at-boundary
+noise between storage iteration orders.
