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

Browse Source 
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)

## Status
WAFER is a working Forth system. It JIT-compiles each word definition to a separate WASM module and executes via `wasmtime`. 261 unit tests passing, **0 errors on Core, Core Extensions, and Exception test suites**.

**Working features:**
- Colon definitions with full control flow (IF/ELSE/THEN, DO/LOOP/+LOOP, BEGIN/UNTIL, BEGIN/WHILE/REPEAT)
- 110+ words: stack, arithmetic, comparison, logic, memory, I/O, defining words, system, exceptions

- Number bases (HEX, DECIMAL), number prefixes ($hex, #dec, %bin)
