算術演算のコマンドライン指定機能を追加

## Overview
算術演算をコマンドライン指定で実行できる機能を追加する。

## Background
算術演算は対話形式のみで実行可能となっている。

## Goal
コマンドラインから算術演算を実行できるように機能追加する。

## Proposal
コマンドラインで算術演算を指定する。
算術演算の計算式もコマンドラインで指定する。
コマンドラインで指定された、計算式を演算し、演算結果を出力する。
演算結果の出力は、対話式と同等の出力とする。

feat(#1): コマンドライン引数 -e による演算機能の追加

## 概要
コマンドライン引数 -e で式を指定して演算できる機能を追加しました。
対話モードを起動せずにワンライナーで計算結果を取得できます。

## 変更内容
- src/main.c — -e オプションを処理する run_eval_mode() を追加。argv[2]以降をスペース結合して式として評価し、対話モードと同等の形式で結果を出力
- src/display.c — help コマンドの出力に 【コマンドライン引数】セクションを追加
- README.md — ## コマンドライン引数セクションを追加、ビルド手順に引数モードの起動例を追記

## 使用例
```
$ ./calc-pgm -e "0xFF & 0x0F"
DEC: 15
HEX: 0xF
OCT: 0o17
BIN: 0b1111

$ ./calc-pgm -e "gib(2)"
= 2147483648

$ ./calc-pgm -e 1 + 2
DEC: 3
HEX: 0x3
OCT: 0o3
BIN: 0b11
```
