v0.3.0-mc26.20

Added

• Added persistent editor projects. Editing state is saved to <dataDir>/projects/<replay>.pbproj on Ctrl+S, from the menu, every 30 seconds, and when the editor closes; the replay file remains authoritative for the timeline duration.
• Added replay of server custom blocks. Block types recorded in the StartGame packet are registered when the replay world loads and rendered with their recorded geometry and materials.
• Added resolution of custom dimensions by their recorded name, so replays can reconstruct dimensions whose ids are not vanilla.
• Added the recording game version to replay metadata. The replay browser refuses to open files recorded on a different Minecraft version and shows both versions.

Changed

• Made keyboard input UI-exclusive while the editor is open unless the left mouse button is held over the game viewport. Escape no longer reaches the game; holding it for 0.8 s exits the editor and saves the project.
• Kept the editor hidden until the replay world is joined and ready, so loading, resource-pack download, and sign-in screens are no longer covered.
• Cut seek time roughly in half by draining chunk injection inline during catch-up and reusing already-applied snapshot columns.
• Downgraded project save/load, keyframe capture, and custom block registration logs to debug.
• Kept the configuration version, recording-file snapshot context version, and new project format version at 1; complete v0.2.1-mc26.20 archives remain compatible and require no conversion.
• Documented that Vibrant Visuals is not supported yet; recording, replay, and export are only validated with the standard renderer.
• Documented that 0.2.0 was skipped on the MC 26.20 line because video export stalled on that runtime, and that 0.2.1 is published for both runtimes.

Fixed

• Fixed replays recorded by a newer build failing outright when a configuration packet had an unknown lifecycle; such packets are now skipped with a warning.
• Fixed Ctrl shortcuts such as undo/redo never triggering because ImGui modifier state was not submitted.
• Fixed the camera preview keeping a stale cached pose after a camera track was toggled.
• Fixed timeline wheel-zoom anchoring to the wrong tick when the cursor was outside the canvas.
• Fixed the property search box discarding typed text every frame.
• Fixed a rewind keeping stale player-list skins instead of re-registering them.
