## Which issue does this PR close?
Closes #5886. Follow-up to #5822.
## Rationale for this change
A singleton map already has its only possible ordering, but normalization
still creates a key slice and invokes Arrow sorting for every row. Avoiding
that work speeds up matched singleton normalization by 19–22x in the full
measurement and 18.4x in an independent forward-order confirmation;
normalization plus hashing improves by 13.84x in the full forward singleton
case.
## What changes are included in this PR?
Skip per-row sort dispatch only for supported flat singleton key types. A
batch check chooses a const-specialized loop so wide maps retain a fallback
without the added per-row singleton branch. Keep nested and unsupported types
on Arrow's validation path, including singleton errors. Preserve global
permutation/take, rebased offsets, physical entries beneath null maps, schema
metadata, and existing early returns. Hashing implementation and nested-hashing
defaults are unchanged.
Extend the shared matched benchmark harness with null, sliced,
mixed-cardinality, long Unicode, empty, singleton, and unsupported-key cases.
Record the local performance audit.
## How are these changes tested?
The unchanged nine map-sort tests and three new tests pass (12 total),
covering manually expected permutations, exact values, schema metadata, null
buffers, nonzero offsets, nested keys, unsupported errors, NaN payloads, signed
zero, and binary keys. All 11 Murmur3 tests pass. Both benchmark smoke runs
pass (92 cases). Full `make` succeeds (native and JVM packaging; JVM tests
skipped by the build target). Workspace all-target Clippy passes with warnings
denied, and Rust formatting passes.
Benchmark environment: Apple M4 Max, macOS 26.6.2, Rust 1.97.1, thin LTO,
one codegen unit, DataFusion 55.0.0. Both sides use commit
3810936b40af3562003120742f7d258b234e4dc5 plus identical benchmark additions and
the same dependency lock (SHA-256
`02a7248aa329e1f98c7cce0ae921601ca66cefae66dd2c08631c98d3ae8337cb`); only the
optimized side includes the production change. These are microbenchmarks, not
end-to-end Spark query speedups.
Criterion: 8192 visible rows, seed 42, 100 samples, 3-second warmup,
5-second requested measurement, 95% confidence, sequential execution with no
concurrent builds. Input construction and checks and hash-buffer allocation are
untimed; seed reset, normalization allocation/drop, and combined struct
construction/drop are timed. No differences between stage or process timings
are presented as exact cost attribution. The unsupported-key benchmark fails at
the first row and is not batch throughput.
All 92 cases were measured. Fourteen initial regression flags were
independently remeasured. The three residual approximately 1.4% flags were
measured again with execution order reversed: hash-only directions reversed and
the combined case returned within the 1% noise threshold. No stable meaningful
regression was observed; confidence intervals within a process do not cover
machine drift. All initial flags remain visible below.

<summary>All 92 cases: timings and 95% confidence intervals</summary>
Timings use Criterion's slope estimate when available, otherwise its mean.
Speedup is the ratio of those point estimates. Regression confirmation
separately uses Criterion's relative mean change, so its percentages need not
equal the slope ratio.
