Remove IIFE wrapper from googleDriveAdapterHelper.js

Changed from IIFE pattern to direct object literal evaluation

Rationale:
- Global variable functions should evaluate to an object directly
- IIFE wrapper was unnecessary complexity
- Simpler pattern: code evaluates to object, not function that returns object
- Matches intended architecture for vm.Script module loading

Changes:
1. Removed IIFE wrapper:
   - Before: (function createHelpers() { ... return {...} })()
   - After: ({ ... })

2. Removed function indentation (2 spaces throughout file)

3. Updated constitution.md:
   - Pattern description: 'IIFE returning object' → 'evaluates to a single object'
   - Clarified: 'not wrapped in IIFE'
   - Updated all pattern references

Structure:
- File defines classes and functions at top level
- Final expression is object literal referencing all functions
- When executed via vm.Script, evaluates to the object
- Object is assigned to globalVariableContext.googleDriveAdapterHelper

Benefits:
✅ Simpler pattern (no function wrapper)
✅ Clearer intent (direct object evaluation)
✅ Matches architecture description
✅ Easier to understand and maintain
✅ Same functionality, cleaner implementation

Before (IIFE):

After (Object Literal):

Testing:
✓ Syntax validated
✓ Server starts successfully
✓ Module loads: 'Loaded global functions: googleDriveAdapterHelper'
✓ All function calls work correctly
✓ Request handling works as expected

 **Helper Functions Pattern**: Pure utility functions (XML escaping, validation, formatting, routing) MAY be extracted to `src/globalVariables/googleDriveAdapterHelper.js` to improve readability and maintainability. The helpers module:
 - MUST be loaded via `vm.Script` (same isolation as proxy.js)
-- MUST return a single object with all helper functions
