fix(lint): fix eslint config and resolve lint errors

- Move ignores to top-level config object (was ineffective inside files block)
- Exclude dist/, coverage/, scripts/, *.d.ts from linting
- Add require to globals for CJS fallback in nip46-signer
- Fix unused variable lint errors (empty catch, _ prefixes)
- 0 errors, 37 warnings (all no-explicit-any in tests)
