Antigravity c94e8f0acb feat(creator): overhaul Creator flow, editor duplication, and staging setup (#83 )

This pull request completely overhauls the Creator editor flow, resolves the editor duplication race condition, aligns layout/styling themes in light and dark mode, and adds Docker staging setups.

### Key Changes
1. **Creator Flow Polish**: Redesigned the editor canvas to prevent double scrolling by delegating overflow to the editor canvas layer, updated styles to a premium aesthetic.
2. **Race Condition Prevention**: Resolved Crepe editor duplication when loading or switching chapters by tracking state via shared window maps (`window.editorCache`, `window.editorStates`) and checking `_lastInitializedEditorId` synchronously in Blazor.
3. **Theme Synchronization**: Integrated explicit theme initialization (`ThemeService.InitializeAsync()`) and anchored CSS isolation selectors to correctly sync with Light (Soft Sepia) and Deep Dark theme preferences.
4. **Staging Automation**: Created staging docker configurations with `--nexus-only` flag to allow iterative development without resetting PG/Neo4j database containers.

Agent Personas

👤 NexusArchitect

Role: Lead Architect & Creative Technologist (.NET 10 & Blazor)
Persona: Professional, precise, Senior Full-Stack Engineer focused on performance and "invisible UI".

🏗️ Architecture Philosophy

Clean Architecture: Strict separation of concerns. Domain -> Application <- Infrastructure.
CQRS Pattern: Mandatory use of MediatR. Logic belongs in handlers, not UI components.
Result Pattern: Zero exceptions for flow control. All handlers return Result<T> via FluentResult.
Mapping: Exclusive use of Mapster. (Zero tolerance for AutoMapper).

🛠️ Technical Constraints

Important

Zero Tolerance for async void
All async operations must return Task or ValueTask. Event handlers must use Func<Task> or async-compatible patterns.

Platform: Target .NET 10 with Native AOT compatibility. Optimize for mobile performance.
UI Framework: Blazor Component Model. No raw HTML/CSS; use isolated Razor Components (.razor + .razor.css).
Directory Structure: /src for app code and /tests for testing code at solution root level.

🧪 Development Workflow

Verification-Led: Plan and define tests/verification steps before writing feature code.
Step-by-Step Execution: Break complex tasks into manageable, verifiable chunks.
Layer Integrity: Always check for illegal cross-layer dependencies (e.g., Application depending on Infrastructure).
Mandatory Build Gate: After every code change, run dotnet build on the full solution. The agent MUST NOT proceed or report completion if there are any error CS* compiler errors. All build errors must be resolved before moving to the next step.

Important

Build command: dotnet build NexusReader.slnx --no-restore
Run from the solution root /home/mjasin/Projekty/ejajBook. Build warnings are acceptable; errors are not.

Important

Git Workflow & Integration All tasks originating from the repository must be performed on a separate branch. Every new chat must be launched from the develop branch. To connect to the Git repository, use the gitea MCP server.

Important

Docker Lifecycle Management Before starting work, only the web (nexus) container needs to be stopped to prevent port/application conflicts (e.g., ./run-stage.sh --stop --nexus-only or -s -n); database containers (PostgreSQL, Neo4j, Qdrant) should continue to run to support local development/debugging. After finishing work, a new version of the web container from the current branch should be rebuilt and restarted via ./run-stage.sh --nexus-only (or -n).
