What Changed

• Added new environment variable GO_BROADCAST_AI_FAIL_ON_ERROR to .github/.env.base with default value false to control error handling behavior for AI failures
• Added documentation comment explaining that when true, AI failures will cause sync to fail with an error (showing which API key env var was used), and when false (default), AI failures silently fall back to static templates
• Updated actions/checkout action from commit hash 8e8c483db84b4bee98b60c0593521ed34d9990e8 (v6.0.1) to de0fac2e4500dabe0009e67214ff5f5447ce83dd (v6.0.2) across 25 workflow files

Why It Was Necessary

• Provides configuration control over AI error handling behavior, allowing users to choose between strict failure mode or silent fallback to static templates
• Improves debugging capability by optionally exposing which API key environment variable was used when AI operations fail
• Updates checkout action to latest patch version for potential bug fixes and security improvements

Testing Performed

• Verified the new environment variable is properly documented with clear behavior description
• Confirmed the checkout action version update syntax is correct across all 25 workflow files
• Validated that the default value of false maintains backward-compatible behavior with existing silent fallback

Impact / Risk

• Breaking Change: None - the new environment variable defaults to false, preserving existing behavior
• Risk: Low - checkout action update is a patch version increment (v6.0.1 to v6.0.2), and the new configuration flag is optional
• Impact: Provides enhanced debugging capabilities for AI broadcast features without affecting current functionality
