feat: add TypeScript types for wif.js

[Copilot]

Add TypeScript types for wif.js ✅

• Create wif.d.ts with type definitions for all exported functions
• Add wif.d.ts to package.json files list
• Add types export to package.json exports for ./wif.js
• Run linter to validate changes (pre-existing linter warnings unrelated to this change)
• Run tests to ensure types work correctly (all 4 tests pass)
• Code review completed (1 false positive about async functions)
• Security scan completed (no issues found)
• Remove package-lock.json (shouldn't be included as project uses pnpm)
• Add detailed documentation for WIF functions to README.md
• Fix parameter name consistency to match implementation
• Match import syntax exactly with README

Summary

Successfully added TypeScript type definitions for the wif.js module, following the same pattern as other modules in the repository (e.g., base64.d.ts, hex.d.ts, base32.d.ts).

Updated README.md with comprehensive documentation for all WIF functions including descriptions, parameters, return values, and error conditions. Parameter names now match the actual implementation.

Import syntax in the type definitions now matches the README exactly (split into two import statements).

Security Summary: No vulnerabilities discovered.
