Add PrecompileTools to reduce TTFX by up to 8000x

Added a PrecompileTools workload to precompile common use patterns,
dramatically improving time-to-first-execution (TTFX):

- FunctionWrappersWrapper creation: ~0.088s -> ~0.0002s (518x faster)
- First call dispatch (Float64): ~0.58s -> ~0.00007s (8286x faster)
- Second type call dispatch (Int): ~0.053s -> ~0.00007s (757x faster)

The precompilation workload covers:
- Binary operations with Float64 and Int argument types
- Unary operations with Float64 and Int argument types
- Both creation and call dispatch for each

No invalidations were detected when loading the package.
