fix: resolve all linting and type errors

- Remove unused React import from nostrUriResolver
- Add block scoping to switch case statements
- Add react-hooks plugin to eslint config
- Fix exhaustive-deps warnings in components
- Fix DecodeResult type to use ReturnType<typeof decode>
- Update dependency arrays to include all used values
- Add eslint-disable comment for intentional dependency omission

All linting warnings resolved. TypeScript type checking passes.
