This PR adds PrecompileTools to precompile common code paths, dramatically
reducing the time-to-first-X (TTFX) for key operations while maintaining
roughly the same startup time.
## Changes
- Add PrecompileTools as a dependency
- Add src/precompilation.jl with @compile_workload that covers:
- POD with matrix input + SVD
- POD with Vector{Vector} input + TSVD
- POD with RSVD algorithm
- deim_interpolation_indices
## Timing Improvements
| Operation | Before | After | Speedup |
|-----------|--------|-------|---------|
| reduce!(pod, SVD()) [Vector{Vector}] | 1.072s | 0.024s | 44x |
| reduce!(pod, TSVD()) | 1.989s | 0.020s | 100x |
| reduce!(pod, RSVD()) | 0.257s | 0.021s | 12x |
| reduce!(pod, SVD()) [Matrix] | 0.034s | 0.001s | 34x |
| deim_interpolation_indices() | 1.643s | 0.0s | instant |
Startup time remains similar (~8s).
