chore(benchmarks): remove three redundant benchmark mains

FullCvBenchmark duplicated the JMH TemplateCvJmhBenchmark (CV through
ModernProfessional) with a hand-rolled, JIT-noisier loop and no report.
GraphComposeBenchmark was an early-engine relic measuring the same
title+body+divider doc as CurrentSpeedBenchmark's engine-simple scenario.
ScalabilityBenchmark's thread-scaling sweep is folded into
CurrentSpeedBenchmark's full-profile throughput run (thread counts now
1,2,4,8,16).

Drop the matching run-benchmarks.ps1 steps and the benchmarks.md /
benchmarks/README.md entries. ComparativeBenchmark, the JMH benches, the
deterministic probes, and the soak/stress runners stay. Benchmark module
compiles; its 28 tests pass.

+- **Benchmark suite cleanup (not shipped).** Removed three redundant
+  benchmark mains: `FullCvBenchmark` (superseded by the JMH
+  `TemplateCvJmhBenchmark`), `GraphComposeBenchmark` (early-engine relic
+  duplicating `CurrentSpeedBenchmark`'s `engine-simple` scenario), and
+  `ScalabilityBenchmark` (its thread-scaling sweep folded into
+  `CurrentSpeedBenchmark`'s full-profile throughput run, now `1,2,4,8,16`).
+  Dropped the matching `run-benchmarks.ps1` steps and doc entries.
 - **Removed the `java.awt.*` / `java.util.*` co-wildcard in four files.**

   `WeeklyScheduleTemplateComposer`, and the engine `PdfRenderingSystemECS`
