Implement Soroban Contract WASM Binary Size Optimization Validation Pipeline

[temma02]

Description

packages/stellar/src/soroban.ts enforces MAX_WASM_SIZE_BYTES but does not report optimization opportunities. Implement a validation pipeline that analyzes WASM binaries for size optimization: unused imports, dead code, and unoptimized sections.

Requirements and Context

• Detect: unused host function imports, unoptimized data segments, redundant type definitions
• Report size breakdown: code section, data section, import section, custom sections
• Suggest optimization actions: strip debug info, enable wasm-opt, remove unused imports
• Pipeline must run in <2 seconds for a 64KB WASM binary

Suggested Execution

Branch: feat/soroban-wasm-size-optimization-pipeline

Implement Changes

• Create wasm-analyzer.ts in packages/stellar/src/
• Parse WASM binary structure using a lightweight WASM section parser
• Compute per-section size contributions and identify largest sections
• Add tests for section parsing, unused import detection, and optimization suggestions

Test and Commit

Run pnpm test --filter=stellar -- wasm-analyzer and confirm section analysis tests produce expected breakdowns.
