Level now fires callbacks when game state changes that require redrawing:
- on-coins-changed!: fired when a coin is eaten or key is picked up
- on-maze-changed!: fired when a door is removed
Exposes set-on-coins-changed! and set-on-maze-changed! messages so the
game ADT can wire these to the draw ADT's dirty flags.

Previously every frame: cleared+redrawed 868 cells for coins, cleared+
redrawed all UI text, emptied+recreated pause layer, and swapped key
sprites repeatedly.
Now uses dirty flags and cached values:
- Coins: only redrawn when coins-dirty? is set (on coin eat/key pickup)
- Maze: only redrawn when a door is removed
- UI: only redrawn when score or time string actually changes
- Key: sprite swap happens exactly once, not every frame
- Pause: layer only modified when paused? state transitions
Exposes mark-coins-dirty! and mark-maze-dirty! messages so the game
ADT can signal changes from the level.

Pac-Man now moves automatically in its current direction every
pacman-speed-ms (200ms). Arrow keys queue a desired turn direction
instead of moving directly. Each movement tick:
1. Try the queued direction — if passable, turn and move that way
2. Otherwise keep moving in the current direction
3. Stop only when hitting a wall (no direction change)
New internal state:
- queued-direction: the direction the player wants to turn next
- movement-timer: accumulates delta-time, triggers move at interval
New helper:
- can-move?: checks if a direction is passable (no wall/locked door)
Changed behavior:
- key-press! now sets queued-direction instead of calling move-pacman!
- update! now drives movement via advance-pacman! on a timer
- move-pacman! no longer checks time-up? (advance-pacman! handles it)

Adds a 200ms movement tick rate, controlling how fast Pac-Man moves
automatically through the maze.

The draw callback receives no delta-time, so animation was stuck at 0.
Split draw-pacman! into draw (position/rotation) and animate-pacman!
(sprite sequence advancement). Animation is now called from the game
loop which has the real delta-time.

New structure groups all ADT modules under adt/ directory, removing
redundant adt- prefix from filenames. Library names now read as
(pacman-project adt position) etc. All imports updated accordingly.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Renamed files: constanten→constants, adt-positie→adt-position,
adt-doolhof→adt-maze, adt-sleutel→adt-key, adt-tijdslimiet→adt-timer,
adt-teken→adt-draw, adt-spel→adt-game. All message names, variables,
comments, and tests converted to English.
Also fixed counter location bug (time-label x/y were swapped).

Tests for Positie, Doolhof, Pac-Man, Score, and Tijdslimiet ADTs
using check/check-eq?/run-test from (pp1 tests) library.
Centralized test runner in alle-testen.rkt with prefix imports.

Connects level (logic) with teken (graphics) via callbacks.
Follows snake-wpo adt-spel pattern exactly.

All rendering (maze, coins, key, pacman, UI, pause) consolidated here.
Grid-to-pixel conversion happens exclusively in this ADT.
Follows snake-wpo pattern with callback registration.

Combines game-logic, keyboard-handler, main-loop, and pause-menu into
single level ADT. Handles movement, collision, teleportation, coin/key
pickup, door opening, pause toggling, and time updates. No graphics.

All hardcoded values (cell sizes, offsets, sprite scales, timing, score,
UI positions, cell type codes) are now named constants in an R7RS library.
