Closes the two open issues and lands the pending unreleased batch:
- #90: `Sprite { atlas: 1 }` routes esys_sprite through atlas_draw_ex
(scale/flip/tint), so cell / cell_span / strip ids of any size draw
through the engine sprite-render system. examples/library/sprite_atlas
is the pixel-readback regression.
- #91: `become` from an @On(Event) listener / global handler / plain
function no longer segfaults the compiler; it emits @L_scene_leave()
(a dispatch on the live scene id) so the leaving scene's on-exit runs.
UI_* handles are readable from any code (widget table built on first
use). examples/library/scene_menus covers it.
- fix: a windowed `ludicc -o` build that reaches the audio runtime only
through the atlas/Assets preload import now links audio.ll +
AVFoundation (the audio backend link was gated on a game-level
Audio.* call, so any windowed game declaring Sprite failed to link).
- the hand-written "Unreleased" CHANGELOG section is converted to
changesets under changes/ so `x release` generates it.
- plus the batch: engine-driven retained UI + UiClicked event, Overlay
phase, TileSkin tilemap-render system, Key.* constants, Font/Ui/File
namespaces, Sprite.strip, prefabs, managers, countdown fields,
enum-typed machines, layer @Queries, ludic.prefs / ludic.dungeon
packages, Ai.seek pathing, Solids.solid2, cursor confine (mode 3)
fix, shooter centre-aim fix, reserved-word function diagnostic.
Verified: x test (124/124), x test-tools, check-impl, check-vocabulary,
check-docs, docs-gen + docs-check, bootstrap-cfree (seed is a fixpoint).

Assets loaded synchronously in Boot stalled the first frame(s). Adds an
Assets.* preload queue over the #81 atlas: Assets.enqueue(name, path) queues a
named image without loading it, Assets.pump(max) loads up to max per frame
(returns how many), and Assets.total/loaded/ready/progress (0..100) drive a
progress bar. A loading scene pumps a few per frame, draws Assets.progress(),
and becomes the play scene once Assets.ready() — the deterministic, no-threads
form of async preloading (work spread across frames; same enqueue+pump order
loads identically every run). Loaded assets are reachable by name via
Assets.get / Sprite.named.
Example preload (enqueue 3, pump incrementally 0->33->66->100, ready flips, get
by name) prints 3 0 0 0 1 33 66 1 100 1. 6 docs pages. Full suite 117/0,
fixpoint holds.

Sprite loading was a bare png_load — one file per 16x16 sprite, no way to load
one sheet and address a cell by grid coords or name. Adds a Sprite.*/Assets.*
runtime (atlas.ludic) over the variable-size image loader, so a cell is a
sub-rect of the kept image and is NOT restricted to the 16x16 sprite table:
Sprite.sheet(path,cw,ch), Sprite.cell(sheet,col,row),
Sprite.cell_span(sheet,col,row,cols,rows) (a sprite may span >1 cell),
Sprite.define/named (name + lookup), Sprite.draw/draw_scaled (through
camera/zoom/clip like Screen.sprite), Sprite.width/height, and
Assets.image/load/get. Spliced on demand (Sprite.sheet/… or Assets.*), so a
program using neither is byte-identical.
Example examples/library/atlas.ludic (verified against a real 12x11 Kenney
sheet, incl. a 2x3 multi-cell span and named lookup). 14 docs pages. Full
suite 114/0, goldens byte-identical, fixpoint holds.
