Phase 1: altimate-core Direct napi-rs Bindings

Parent: #214
Depends on: Phase 0

What

Replace 41 Python bridge methods with direct calls to @altimateai/altimate-core npm package (napi-rs Node.js bindings for the Rust SQL engine).

Sub-tasks

• Verify @altimateai/altimate-core npm API matches Python guard.py signatures
• Audit IFF/QUALIFY transpile pre/post processing in guard.py
• Add @altimateai/altimate-core dependency
• Create native/altimate-core.ts — 33 method wrappers
• Create native/schema-resolver.ts — Schema.fromFile/fromJson/fromDdl
• Create native/sql/analyze.ts — lint + semantics + safety composite
• Create native/sql/optimize.ts — rewrite + lint composite
• Create native/sql/translate.ts — transpile with IFF/QUALIFY transforms
• Create native/sql/{format,fix,rewrite,diff,lineage}.ts
• Register all 41 methods in dispatcher
• Shadow mode parity tests (fuzzy comparison)
• ALTIMATE_NATIVE_ONLY=1 passes for all 41 methods

Methods (41 total)

33 altimate_core.* + 8 composite sql.* (analyze, optimize, translate, format, fix, rewrite, diff, lineage.check)
