Refactor to unified caesar() function with encode/decode support

Browse Source 
- Replace separate encrypt/decrypt with shared caesar() function
- Add direction constants (DIRECTION_ENCODE, DIRECTION_DECODE) and
  prompts
- Update main.py to support interactive encode/decode loop
- Keep encrypt/decrypt as wrappers for backward compatibility
- Add tests for caesar() with both directions and error handling
- Update tests for main.py with interactive scenario tests

## 🧭 Overview
The Caesar cipher shifts every letter by a fixed number of places (with a shift of 3, `E` becomes `H`). This project, from Udemy's *100 Days of Code: The Complete Python Pro Bootcamp* (Day 8), finds letter positions with `list.index` and wraps around the alphabet with the modulo operator. Parts 1 and 2 cover encryption and decryption; a combined program follows in Part 3. Code lives in `src/`, tests in `tests/`, docs in `docs/`.

This project, from Udemy's *100 Days of Code: The Complete Python Pro Bootcamp* (Day 8), finds letter positions with `list.index` and wraps around the alphabet with the modulo operator. The interactive program lets you encode or decode as many messages as you like. Code lives in `src/`, tests in `tests/`, docs in `docs/`.
