Feat/js ant simulation core - #3

…th-setup-script

Add JS port plan and setup script

Update instructions for task tracking

This commit includes the initial JavaScript port of the Unity ant simulation.

Key functionalities implemented:
- HTML setup with a canvas for rendering.
- Core simulation classes:
    - AntSettings: Manages simulation parameters.
    - Vector2: Handles 2D vector operations.
    - PerceptionMap: Manages pheromone creation, storage, and lookup with decay.
    - FoodSource: Spawns and manages food items with clustered, seedable random distribution.
    - Ant: Controls individual ant behavior including states (searching, returning), movement, steering, food collection, and pheromone interaction.
    - AntColony: Manages the ant population, spawning, and interfaces with perception maps.
- Rendering:
    - Renderer class draws the colony, ants (oriented and colored by state), food items, and pheromone trails (home and food) on the canvas.
- Main simulation loop:
    - Initializes all components.
    - Runs the update and render cycle using requestAnimationFrame.

Current state:
The simulation is visually functional. Ants navigate, interact with food and pheromones.
Collision detection (ant-ant, ant-obstacle) is the next major feature planned and is not yet implemented.
