Add -sUSE_WEBGL2=1 -sMIN_WEBGL_VERSION=2 -sMAX_WEBGL_VERSION=2 to both
EMCC_CFLAGS and linker flags. raylib 5.x enables VAOs by default which
require WebGL2; without it glVertexAttribPointer fails on the clientside
property of an undefined VAO object.

- Cargo.toml: gate `wayland` feature behind cfg(not(wasm32)) so the
dependency resolves correctly for both native and web targets
- .cargo/config.toml: WASM linker flags (ASYNCIFY, GLFW, memory growth)
- build_web.sh: sets required EMCC_CFLAGS, builds, copies artefacts to web/;
accepts --serve to start a local HTTP server
- web/index.html: minimal Emscripten shell with canvas and status line
- .gitignore: exclude generated web/*.js and web/*.wasm artefacts
- README: document web build prerequisites and usage
ASYNCIFY lets the native while-loop main loop run unchanged in the browser.
Build output: ~267 KB JS + ~458 KB WASM.

Bugs fixed:
- Remove duplicate/corrupt draw_text in draw_active_effects_hud (screen_width as u8 = 0)
- Fix pickup-enemy avoidance using actual enemy center-x instead of platform midpoint
- Remove redundant `as f32` cast on an already-f32 expression
DRY / data coupling:
- Effect label and color now stored in each effect struct and passed from PickupDef::create_effect,
eliminating the three-way duplication between Config, PickupEffectType, and ActiveEffect impls
Config-driven level gen:
- Add enemy_platform_margin and pickup_platform_margin fields to Config
- Replace magic number literals in level_gen with cfg fields
Encapsulation and code clarity:
- score_f made fully private; tests assert on the public score: u64
- Pickup::collected flag removed; collect_pickups uses retain for immediate removal
- Platform::top() and Enemy::top() removed (transparent aliases for .y); call sites use .y directly
- Game-over restart prompt now blinks at ~2 Hz using world.elapsed
Rust idioms:
- #[derive(Debug)] added to Player, Platform, Enemy, Pickup, PickupDef,
PickupEffectType, Config, GameState, and all three effect structs
- [profile.release] added to Cargo.toml (lto=thin, codegen-units=1, panic=abort)
