Integration with ShortCut

Description: We need a first-class integration between Sleekplan and Shortcut that keeps work items synced between both systems. Purpose: Enable Sleekplan items to flow into Shortcut (and back) so product feedback and execution remain linked, reducing manual work and improving traceability. Benefits: Keeps product and engineering work in sync without manual copying. Improves adoption for teams that use Shortcut as their PM tool. Provides direct links between Sleekplan posts and Shortcut issues for context. Key Features: Bi-directional sync of items (Sleekplan Shortcut). Mapping of Sleekplan item types to Shortcut entities (e.g., Epic, Story). Status synchronization so updates in either system reflect in the other. Configurable field mappings (type, status, minimal metadata like title and link). Webhook-driven or scheduled sync with conflict-resolution rules. Optional extensions: sync comments and assignees in a later phase. Acceptance criteria: Creating or updating a Sleekplan post can create or update the corresponding Shortcut issue. Status changes in Shortcut update the Sleekplan post status (and vice versa). Links to the corresponding item appear in both systems.
