Update plugin typings

[knguyen-figma]

Update generated plugin typings (plugin-api.d.ts and plugin-api-standalone.d.ts).

Changes

Slot component properties

• Added new SlotSettings type with stretchChildOnInsert, displayEmptyByDefault, minChildren, maxChildren, and allowPreferredValuesOnly fields.
• Added optional slotSettings to component property options/definitions (only supported for 'SLOT' properties).
• Added a readonly limitViolations property to SlotNode ('BELOW_MIN' | 'ABOVE_MAX' | 'HAS_NON_PREFERRED') reporting which configured slot limits the current contents violate.
• Exported SlotSettings.

Transform modifiers

• TransformModifier is now a union type (LinearRepeatModifier | RadialRepeatModifier) instead of an empty interface.
• RepeatModifier no longer extends TransformModifier.

Variable binding

• Component property definition binding now uses VariableBindableComponentPropertyDefinitionField instead of VariableBindableComponentPropertyField.

Docs / formatting

• Various JSDoc whitespace and formatting cleanups (added blank lines, fixed missing spaces before */ in brush/stroke comments, corner-radius doc text).
