Extract helper functions from proxy.js into helpers.js module
- Create src/globalVariables/helpers.js (315 lines)
- Extract 11 pure utility functions from proxy.js
- Reduce proxy.js from 752 to 493 lines (35% reduction)
- Load helpers via vm.Script with same isolation pattern
- Update constitution to document helper extraction pattern
Extracted functions:
- generateRequestId, validateDocumentId, validateDocumentCount
- escapeXml, mapDriveErrorToHttp
- toSitemapEntry, transformDocumentsToSitemapEntries
- generateSitemapXML, generateSitemap
- parseRoute, DocumentCountExceededError class
Architecture:
- helpers.js loaded via vm.Script (IIFE returning object)
- Injected as 'helpers' global object into VM context
- proxy.js accesses via helpers.functionName() pattern
- Maintains zero-import isolation pattern
Constitution version: 1.16.0 → 1.17.0
