Sprint 284: poly-compiler (steps 1948–1952)

5-phase compiler pipeline: C++(lex)→Haskell(parse)→Rust(typecheck)→Lisp(optimize)→Go(emit)

Components:
- CompilerPhaseSpec + CompilerPhaseRegistry: phase descriptors sorted by order field
- CompilerIRNode + IRNodePipeline: IR node kinds (Source→Token→AST→TypedAST→OptimizedAST→Bytecode) + queue
- CompilerPhaseRouter: IRNodeKind→phaseId routing with optional fallback
- CompilerPipelineRunner: chains PhaseTransform functions in order, supports runUpTo

26/26 tests pass.

// Step 1952: Sprint 284 Integration — poly-compiler
//
// 5-phase pipeline: C++(lex)→Haskell(parse)→Rust(typecheck)→Lisp(optimize)→Go(emit)
//
// t1: registry has 5 phases sorted by order; languages correct
// t2: router maps all 5 IRNodeKinds to correct phases
// t3: pipeline runner runAll produces Bytecode from Source
// t4: runUpTo("typecheck") produces TypedAST
// t5: Sprint284IntegrationSummary reports 5 steps
