Fix all ESLint warnings

- Fixed long lines by splitting template literals
- Replaced all 'any' types with proper types:
  - Used ToolResponse type instead of any
  - Used z.ZodError for Zod validation errors
  - Created JSONSchema interface for zod-to-json-schema
  - Added ServerStatusData interface
  - Used Record<string, unknown> for metadata
  - Created ZodDefAny type for internal Zod properties
- Fixed quote style to use double quotes
- Removed trailing spaces

All ESLint issues resolved (0 errors, 0 warnings)
