feat: Add no-useless-catch ESLint rule

Enforce the `no-useless-catch` ESLint rule across the codebase.
This rule disallows `catch` clauses that only rethrow the caught error,
which provides no additional value and can make debugging harder.

This change adds the rule as an "error" to:
- The root ESLint configuration ([](/.eslintrc.json))
- The webview UI ESLint configuration ([](webview-ui/.eslintrc.json))

This ensures that all `catch` blocks either handle the error meaningfully
or are omitted if the error should propagate.
