Add switchable optimization config and benchmark framework

WaferConfig: unified config controlling all optimizations individually.
ForthVM::new_with_config(config) to create VMs with custom optimization settings.
All 8 switchable optimizations: peephole, constant_fold, strength_reduce, dce,
tail_call, inline (IR passes) + stack_to_local_promotion (codegen).

Benchmark framework (crates/core/tests/benchmark_report.rs):
- 7 Forth benchmarks: Fibonacci, Factorial, SumRecurse, NestedLoops, GCD, MemFill, Collatz
- Correctness verification across all configs (runs in CI)
- Full report with 128 optimization combinations (cargo test --ignored)
- Measures execution time, compilation time, WASM module bytes
- CONSOLIDATE impact comparison

Key findings from benchmark report:
- Inlining: -77% exec time on Fibonacci, -92% on Collatz
- Stack-to-local promotion: -5.5% WASM module size
- CONSOLIDATE: -72% exec time on Fibonacci (call_indirect -> direct call)
- All optimizations combined: best overall performance

Add working compliance test harness, 11 word sets at 100%

Replace placeholder compliance tests with real harness that boots WAFER,
loads Gerry Jackson's test suite, and asserts 0 errors per word set.

Passing word sets (11/13):
  Core, Core Plus, Core Ext, Exception, Double-Number, String,
  Search-Order, Memory-Allocation, Programming-Tools, Facility, Locals

Not yet: File-Access (needs WASI), Floating-Point, Extended-Character
272 total tests (261 unit + 11 compliance)

Initial commit: WAFER (WebAssembly Forth Engine in Rust)

Optimizing Forth 2012 compiler targeting WebAssembly with IR-based
compilation pipeline, multi-typed stack inference, subroutine threading,
and JIT/consolidation modes. Rust kernel with ~35 primitives and Forth
standard library for core/core-ext word sets.
