Revised the specification to align with the agreed design direction:

• EasyGrid is a configurator, not a component. It wraps an externally instantiated Grid; the caller owns data binding, selection, events, and all standard Grid interactions.
• EasyColumn is narrowed to only what EasyGrid uniquely provides: type-specific formatting (withDateFormat, withNumberFormat, withBooleanLabels, withValueFormatter). Everything else goes through getColumn() to avoid duplicating Grid.Column's API.
• Export removed — out of scope for this add-on.
• Row actions extracted to FEATURE_ROW_ACTIONS.md to keep the main spec focused; SPECIFICATIONS.md now just references it.
• Non-goals updated to explicitly call out Grid/GridHelper territory (data binding, selection, events, filtering).
