feat: Enable Moving Tasks Between Projects

[aacevski]

Problem Statement

Users often need to reorganize their work by moving tasks between different projects, but currently there's no way to do this without recreating tasks. This leads to lost history, comments, and attachments when tasks need to be relocated.

Proposed Solution

Implement functionality that allows users to:

• Move tasks from one project to another while preserving all task data
• Optionally adjust task status when moving between projects with different workflows
• Maintain task history, comments, and attachments during the move
• Provide clear UI for selecting the destination project

Alternative Solutions

• Duplicating tasks and manually copying information
• Using cross-project references or links
• Creating a shared backlog across projects

Relevant Context

Task reorganization is common as projects evolve and priorities shift. The ability to move tasks between projects is a standard feature in mature project management tools.

Does this feature align with Kaneo's focus on simplicity?

Yes, because it reduces manual work and prevents data loss when reorganizing work, maintaining a clean workflow without requiring workarounds.
