Update ESLint and related linting packages (including @typescript-eslint v8 for TypeScript 5.9.x)

[coderabbitai]

Background

PR #371 bumped TypeScript from 5.7.x to 5.9.3. However, the current @typescript-eslint packages (@typescript-eslint/parser and @typescript-eslint/eslint-plugin) are still pinned at v5.62.0, which officially supports TypeScript only up to ~5.1. Running npm run lint currently succeeds but emits an unsupported TypeScript version warning.

This issue tracks a follow-up upgrade of ESLint and all related linting packages.

Packages to update

Package	Current version	Target
@typescript-eslint/eslint-plugin	^5.62.0	v8.39.0+
@typescript-eslint/parser	^5.62.0	v8.39.0+
eslint	^8.57.1	latest (v9.x)
eslint-config-prettier	^8.10.0	latest
eslint-plugin-cypress	^2.15.1	latest
eslint-plugin-perfectionist	^2.6.0	latest
eslint-plugin-prettier	^5.1.3	latest
eslint-plugin-react	^7.34.0	latest
eslint-plugin-react-hooks	^4.6.0	latest
eslint-plugin-simple-import-sort	^12.0.0	latest

Notes

• @typescript-eslint v8 requires ESLint 8.56.0+ or ESLint 9.x; upgrading to ESLint 9 (flat config) is the recommended path.
• ESLint 9 introduces a new flat config format (eslint.config.js). The existing .eslintrc-based config will need to be migrated.
• All eslint-plugin-* packages should be checked for ESLint 9 / @typescript-eslint v8 compatibility before upgrading.
