chore(sha256): Review build configuration

[tassoevan]

Proposed changes (including videos or screenshots)

This pull request makes several updates to the build and lint configuration for the packages/sha256 package. The main changes remove Babel-related configuration and dependencies, simplify ESLint settings, and adjust TypeScript build options for better output management.

Build system cleanup:

• Removed Babel configuration file babel.config.js and related dependencies from package.json, indicating the package no longer uses Babel for transpilation. [1] [2]

Linting configuration updates:

• Simplified .eslintrc.json by removing the jest plugin and environment settings, streamlining the linting process.
• Removed TypeScript ESLint plugin and parser dependencies from package.json, further simplifying lint setup.

TypeScript configuration improvements:

• Moved the outDir setting from tsconfig.json to tsconfig.build.json for clearer separation between source and build configuration. [1] [2]
• Updated the exclude pattern in tsconfig.build.json to only exclude TypeScript spec files, ensuring proper build output.

Walkthrough

This PR streamlines the build configuration for the sha256 package by removing Jest-related ESLint rules, deleting the Babel configuration file, removing unused Babel and TypeScript ESLint dev dependencies, and reorganizing TypeScript compiler options between base and build-specific configs.

Changes

Cohort / File(s)	Summary
ESLint & Babel configuration packages/sha256/.eslintrc.json, packages/sha256/babel.config.js	Removed Jest plugin and globals configuration from ESLint. Deleted entire Babel configuration file (preset-env).
Dependencies packages/sha256/package.json	Removed four dev dependencies: @babel/core, @babel/preset-env, @typescript-eslint/eslint-plugin, and @typescript-eslint/parser.
TypeScript build configuration packages/sha256/tsconfig.json, packages/sha256/tsconfig.build.json	Moved "outDir": "dist" from base config to build-specific config. Removed "strictNullChecks": true from base config. Removed "**/*.spec.js" from exclude patterns in build config.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

🐰 Babel and Jest, we bid you adieu,
Config cleaned up, dependencies too,
TypeScript now builds with outDir so fine,
Dependencies slim, the package will shine! ✨

🔇 Additional comments (2)

packages/sha256/tsconfig.build.json (2)

4-4: LGTM! Good practice to separate build output configuration.

Moving outDir to the build-specific configuration separates build artifacts from the base TypeScript configuration used by IDEs and editors.

---

11-11: The exclude pattern correctly targets the package's actual test files. Only TypeScript spec files (.spec.ts) exist in this package, and the pattern appropriately excludes them from the build output.
