What steps can reproduce the bug?

• Send requests with optional cookies or cookies that fail custom validation.
• Observe incorrect status codes or validation errors.
• Inspect cookie configs and afterHandle behavior.

What is the expected behavior?

• Cookies should validate correctly according to their schema.
• Application-level cookie configs should be applied.
• AfterHandle loops should execute efficiently.
• Error handlers should correctly await promises.

What do you see instead?

• Cookies failing validation even when noValidate: true is set.
• Application-level cookie settings not applied.
• Redundant assignments in afterHandle loop.
• Error responses may not resolve correctly for async handlers.

Additional information

• Affects src/compose.ts in the composeHandler function.
• Relevant lines: 1493-1535 (Cookie Validator), 1617-1624 (afterHandle loop), 1939 (error handler promise handling).
• PR can fix all issues together: correct cookie validation, merge app config, optimize afterHandle, and fix error promise.

Have you try removing the node_modules and bun.lockb and try again yet?
