Overview

The editor has basic fly, pan, orbit, focus, and numeric bookmarks, but it lacks the navigation commands and configurable preferences expected in a production DCC or game-engine editor.

Context

Focus and bookmark inputs are currently routed only in RMB Fly state. The feature should preserve current default bindings while allowing a familiar profile to be selected and persisted per user.

Depends on #780 and #782.

What needs to be done

1. Make frame selected and frame all work whenever the viewport has keyboard focus.
2. Add named, persistent camera bookmarks.
3. Add perspective/orthographic switching and axis-aligned view shortcuts.
4. Add configurable movement speed, scroll behavior, mouse sensitivity, and invert-Y.
5. Add rebindable navigation profiles such as Unreal, Maya, and Blender conventions.
6. Persist user preferences and per-scene camera state with safe defaults/migration.

• ZEngine/docs/future-plan/fly-camera-redesign.md

Testing

• Unit-test profile/default resolution and serialization/migration.
• Manually verify each navigation profile in the viewport.
• Verify preferences survive editor restart and invalid configuration falls back safely.

Acceptance criteria

• Frame selected/all work with focused viewport without RMB fly mode.
• Bookmarks can be named and persist across restart.
• Perspective, orthographic, and aligned-view commands are available.
• Navigation preferences are configurable, rebindable, and persisted.
• Existing default controls remain usable after migration.
• Builds without warnings in Debug and Release.
• All relevant unit tests pass.
• No regression in existing functionality.
