docs: update guidelines for Svelte module changes and linting requirements

- Enhanced documentation in AGENTS.md and web/README.md to clarify the mandatory steps for running `npm run check` and `npm run lint` before finalizing changes in the `web/**` directory.
- Updated engineering rules in .cursor/rules/engineering.mdc to specify the necessity of both commands and the use of Prettier for formatting issues.
- Added detailed instructions for handling linting failures and emphasized the importance of these checks in CI workflows.
