fix(interactive): fix syntax error from smart quote and add cache-busting

SUMMARY:
Fixed critical syntax error in interactive-diagram.js caused by smart
quote character and updated cache-busting version.

ISSUE:
Line 26 had a smart quote (') instead of regular apostrophe (')
JavaScript parser treated it as string terminator, causing:
  Uncaught SyntaxError: Unexpected identifier 's'

FIX:
1. Changed smart quote to regular text in promise field
2. Updated cache-busting version from v=20251019160000 to v=20251019162000

IMPACT:
Interactive diagram now loads without syntax errors. Users can click
central core and all service nodes to explore governance architecture.
