Manim Studio 1.1.0

Added

Editable timeline — timeline edits are anchored patches stored in
<scene>.studio.json; per-animation lanes, an editable block inspector,
orphan tray, icon toolbar, block context menu, exact-duration entry,
snapping (frames, 0.1 s, edges), zoom buttons/fit-selection, scrollbar,
insert-wait-at-playhead, loop range and playback speed. Exports bake the
edits in (--no-sidecar to skip).
Block highlight that follows the editor caret; Play from playhead.
Themes — Chalkboard theme and loadable JSON theme files; new editor
header/toolbar, rounded popup menus and a regenerated app icon.
"Reload preview, discard frame cache" action; LaTeX caching.
Welcome starter scene.

Renamed the product from "Manim Editor" to Manim Studio: the import
package is now manim_studio, the CLI is manim-studio, and the Windows
org/bundle identity is ManimStudio.
Renamed the LaTeX override environment variable MANIM_EDITOR_LATEX_DIR to
MANIM_STUDIO_LATEX_DIR.
Rendering performance: single-pass filmstrip crawl, filmstrip reuse across
reloads and retimes, traced scene reused as the initial scene, preview
frames scaled fast then settled smooth.
Preview protocol bumped to v4 (timeline patches).
Removed the render-preview scrub bar; block actions moved to the toolbar.

A block with many animations no longer pushes the preview off screen.
Reliable play/pause, loop and review-speed behaviour (loop stops when turned
off, pause stops a running loop, speed changes real wall-clock pace).
Later blocks stay reachable after a section is lengthened.
Selected code stays readable with a themed selection band.

LICENSE (MIT), CI workflow (format, lint, types, tests on Ubuntu +
Windows), tagged release workflow, Dependabot config, community files and
issue/PR templates.
