This adds a precompilation workload to OptimizationBase that precompiles the most common operations: OptimizationFunction and OptimizationProblem creation with and without bounds. ## Performance improvements - TTFX for OptimizationProblem creation: 0.081s -> 0.024s (~70% improvement) - Loading time remains essentially unchanged (~1.33s) ## Analysis performed - Measured baseline startup and TTFX times - Checked for invalidations using SnoopCompile (32 minor trees, all from dependencies, none actionable) - Profiled inference during TTFX to identify precompilation targets - Added minimal precompile workload for common use cases 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Those types are in SciMLBase, so the precompilation here is in the wrong repo. |

Summary
Performance Improvements
Analysis Performed
Baseline measurements: Measured startup time (~1.33s) and TTFX for OptimizationProblem creation (~0.081s)
Invalidation analysis: Used SnoopCompile to check for invalidations. Found 32 minor invalidation trees (1 child each), all from external dependencies (FillArrays, SparseConnectivityTracer, RecursiveArrayTools, SciMLBase) - none actionable for this package.
TTFX profiling: Used @snoop_inference to profile inference during first use. Most time spent in Base, Core, and SparseMatrixColorings rather than OptimizationBase/SciMLBase code.
Precompilation workload: Added minimal workload that covers the most common use case - creating OptimizationFunction and OptimizationProblem with and without bounds.
Test Results
All OptimizationBase tests pass (703 tests in ~8.5 minutes).
