Tirsvad 3c99040b96 Add Blackjack game: rules, card rendering, game loop and tests
Implement the playable console game for gateway MIL-002.

- rules.py: deal_card, calculate_score (blackjack = 0, aces drop 11 ->
  1)
  and compare with an Outcome enum; no console I/O
- display.py: hand rendering as plain-text rank plus suit emoji (keycap
  emoji rendered as boxes in common terminals), score formatting and
  outcome messages
- art.py: course logo shown at the start of every game
- game.py: play_game (hit/stand, dealer draws below 17), play (restart
  loop, console clear, logo) and ask_yes_no with re-prompt; read, write
  and draw are injected so games can be scripted
- __main__.py: python -m blackjack entry point, exits cleanly on
  Ctrl+C/Ctrl+D
- constants.py: card ranks and suits, prompts and messages
- tests: 32 new unit and scripted end-to-end tests (35 in total)
- README: run instructions for python -m blackjack

# Blackjack
A console Blackjack game against a computer dealer, played with emoji cards.
It is the day 11 capstone of Udemy's *100 Days of Code: The Complete Python Pro
Bootcamp*, built with a plan-first process (milestones and issues in `docs/`).
## House rules
- The deck is unlimited; cards are not removed when drawn. No jokers.
- Jack, Queen and King count 10. An ace counts 11 or 1.
- A two-card hand of ace + 10 is a blackjack.
- The computer is the dealer and draws while its score is below 17.
## Requirements
- Python 3.13 or newer
- No runtime dependencies
- Optional: [Doxygen](https://www.doxygen.nl/) to build the source documentation
- A terminal with UTF-8 and emoji support (for example Windows Terminal)
## Setup
Create and activate a local virtual environment, upgrade pip, then install the
project in editable mode with the development tools.
Windows (PowerShell):
```powershell
python -m venv .venv
.\.venv\Scripts\Activate.ps1
python -m pip install --upgrade pip
python -m pip install -e ".[dev]"
```
Linux and macOS:
```bash
python3 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install -e ".[dev]"
```
Leave the environment with `deactivate`.
## Run
Start the game from the activated virtual environment:
```bash
python -m blackjack
```
## Test
```bash
python -m unittest discover -s tests
```
`pytest` also runs the same tests (`python -m pytest`).
## Lint and type check
```bash
ruff check .
ruff format --check .
mypy src
```
## Documentation
Generate the source documentation (Doxygen comments in `src/`) into
`docs/doxygen/`:
```bash
doxygen Doxyfile
```
Planning documents (business case, stakeholder analysis, project plan and
milestones) are in `docs/`.
## Project layout
