Version 0.3.2

Changed

• Unified lazy caching mechanism for permission evaluation across WebSocketHandler, Include, and BaseRouter.
• handle_permissions() now caches the effective permissions on first evaluation instead of mutating per-request state.
• Internal __slots__ updated for clarity and memory optimization.

Fixed

• Avoided redundant recomputation of permissions and lilya_permissions in nested routing structures.
• Prevented potential state mutation during concurrent permission evaluation.
