[observations]
- Initial execution failed because `bunx` is not available in the sandbox.
[analysis]
- Need inspect `packages/ui/src/Form.ts` around the reported lines and surrounding method.
[pending]
- Determine source syntax shape around `Promise.all` and `.catch`.
- Determine whether parsing concern and validation-state cleanup concern hold.
[actions]
- Read relevant sections of `packages/ui/src/Form.ts`.
- Use a read-only static parser/TypeScript compiler diagnostic if available.

Remove the dangling .catch after Form.

packages/ui/src/Form.ts:142 is outside the Form class body and is not attached to an expression, so the file is invalid TypeScript. If validation rejection handling is needed, wrap the await Promise.all(validationPromises) call inside submit() and reset _isValidating / call markDirty() in a finally block.

[error] 142-142: The @termuijs/ui build failed during 'tsup' because '.catch(err => console.error("Promise.all failed:", err));' is syntactically unexpected. TypeScript also reports missing try, closing parenthesis, and semicolon tokens.

[error] 142-142: The @termuijs/ui build command 'tsup' failed due to an unexpected '.' in '.catch(err => console.error("Promise.all failed:", err));'. TypeScript also reported declaration/statement and syntax errors on this line.

In `@packages/ui/src/Form.ts` around lines 141 - 142, Remove the dangling .catch
after the Form class. In Form.submit(), handle rejection from await
Promise.all(validationPromises) within the method and use finally to reset
_isValidating and call markDirty() when validation handling is required.
