chore: enforce consistent coding style and semicolon removal

- Update ESLint configuration to enforce no semicolons (`semi: ['error', 'never']`)
- Fix all instances of semicolons in `*.ts` files to align with style rules
- Adjust related ESLint rules for `no-extra-semi`
- Simplify unnecessary semicolon patterns in global variable assignments
