Instrument full Neo VM benchmarking coverage for opcodes, syscalls, and native methods

[Jim8y]

Description

• Establish a dedicated benchmarking harness that exercises every Neo VM opcode, syscall, and native contract method across baseline, single-call, and saturated profiles so we can observe how execution behaves as inputs scale.
• Record end-to-end runtime, allocations, stack depth, and gas deltas for each scenario via a shared BenchmarkResultRecorder, then consolidate the data into component-specific CSVs plus a global scaling report to highlight complexity trends.
• Add coverage tracking (with enforcement in the final report) to flag any opcode, syscall, or native manifest method that lacks a benchmark, eliminating silent gaps when the VM surface evolves.
• Seed native benchmarks with deterministic protocol settings and snapshot helpers to remove the multisig bootstrap crash and keep scenarios consistent regardless of user configuration.
• Document the benchmarking workflow, coverage expectations, and dynamic pricing methodology so teams can reproduce runs and interpret the resulting artifacts.

Fixes # (issue)

Type of change

• Optimization (the change is only an optimization)
• Style (the change is only a code style for better maintenance or standard purpose)
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update
