* fix(perf): align direct-SST CREATE TABLE with baked index metadata
The offline fixture generator (query_perf_fixture::direct_sst::
build_region_metadata) bakes greptime:inverted_index /
greptime:skipping_index field metadata into the region manifest for
tag/field columns, but create_table_sql emitted a bare CREATE TABLE
without those declarations. MergeScan's remote-schema validation then
failed on any tag/field projection (HTTP 500 'advertised remote stream
schema field mismatch'), breaking direct_readable_sst perf cases.
CREATE TABLE now declares the matching SKIPPING INDEX WITH
(granularity='1') / INVERTED INDEX column options. A round-trip test
proves the emitted SQL is parser-valid and yields the exact catalog
metadata.

* perf(servers): speed up Prometheus JSON response building with ryu and per-series entry reuse
PrometheusJsonResponse::record_batches_to_data spends ~47% of its CPU
in f64::to_string() per sample and ~32% in IndexMap::entry() per row
(60s profile of concurrent query_range workloads, ~800k series).
- Replace f64::to_string() with ryu::Buffer::format_finite for finite
values (shortest round-trip, 3-5x faster); NaN/+Inf/-Inf keep the
previous std formatting so wire output is unchanged.
- Remember the previous row's label vector and entry index; query output
is clustered by series, so consecutive rows reuse the same IndexMap
entry via get_index_mut instead of rebuilding and hashing the label
vector (worst case adds one Vec comparison per series transition).
Also adds a query-regression case (prom_json_response) that measures the
real Prometheus HTTP range API path (/v1/prometheus/api/v1/query_range),
which is the only frontend path that builds the Prometheus JSON response
(TQL ANALYZE formats the SQL JSON shape instead), plus a prom_http query
kind in the regression runner.
Perf (aligned base d90cca4b75, 256 series x 481 points):
- prom_range_2h (JSON response path): 29.31ms -> 21.46ms (-26.8%)
- tql_range_2h_control (non-JSON path): +1.87% (noise)

* fix(servers): keep Prometheus wire format for integral floats with ryu
ryu::Buffer::format_finite prints integral values as "1.0", but the
Prometheus JSON wire format (matching std f64::to_string) expects "1".
Strip the trailing ".0" that ryu only emits for integral values; extreme
values keep ryu scientific notation, and NaN/Inf keep std output. Adds
wire-format tests covering 1.0, 0.0, -0.0, 1.5, 0.1, 1e21, 1e30, 1e-7,
f64::MAX, NaN, ±Inf.

* perf(promql): use two pointers for sliding range boundaries
Replace the stale cursor heuristic in RangeManipulateStream::calculate_range
with monotonic left/right cursors. The old path rescanned each evaluation
window (O(E x samples-per-window)) and could lose valid samples after sparse
gaps or trailing empty windows. The two pointers keep strict monotonic
progress, reducing boundary generation to O(N + E) while preserving
(curr-range, curr] semantics, start/end shortening, and empty-window output.
Controlled release benchmarks (fixed CPU, ABBA):
- Public RangeManipulate wall time: ~28% faster at 1m/15s, ~66% at 5m/15s,
~96% at 1h/15s.
- Warmed distributed TQL ANALYZE 1h queries: ~17-21% faster end to end;
shorter windows stayed within run-order noise.

* perf(promql): specialize changes/resets with adaptive edge counting
The generic range_fn macro slices, downcasts, and rescans every overlapping
window for changes() and resets(). Replace the macro path for these two
functions with hand-written UDF wrappers backed by a shared private
edge-count kernel: direct raw-offset scans when requested edges are few,
otherwise one global u64 edge prefix so each window is answered by a prefix
difference.
Behavior is preserved bit-for-bit, including raw null-buffer values, NaN
semantics, signed zero, infinities, empty/singleton windows, independent
timestamp/value offsets, arbitrary window layouts, and exact DataFusion
error messages. The shared proc macro, planner, serializer, and other range
functions are untouched.
Controlled release benchmarks (fixed CPU, ABBA):
- Dense sliding windows (k=4/20/240): 91.7-95.6% less public UDF wall time.
- Low-coverage fallback (N=4096, 8 windows): 73.9-74.4% faster.
- Warmed distributed TQL ANALYZE 5m/1h changes/resets: 12.1-19.7% client
and 12.0-20.9% server latency improvement; controls stayed within drift.

* ci(query-regression): include PromQL range boundary case in defaults
An audit of historical query-regression runs found zero range-query
coverage: all 208 PromQL ANALYZE samples were bare selectors, so range
evaluation could regress without CI noticing. Wire the
promql_range_boundary case (introduced in #8646) into DEFAULT_CASES so
label-triggered runs measure the range path. The case is cheap: a ~0.3s
synthetic fixture and about a minute of query execution per base/candidate
pass.
