Descripción

Fixes #1253.

When baileyGenerateImage rejects, such as when the QR image cannot be written, the async connection.update listener also rejects. This leaves an unhandled rejection instead of a controlled provider error. Existing missing-image HTTP behavior is unchanged and continues to return 404.

Changes

• Catch QR image-generation failures at the connection-event boundary.
• Log a contextual error and emit a provider notice containing the failure reason.
• Preserve the existing require_action event and raw QR payload so other QR consumers keep working.
• Add a regression that invokes the real connection handler with a rejected image write.

Verification

• The regression rejected before the fix; it now resolves and emits the expected notice.
• Lifecycle tests: 19/19 passed.
• Baileys provider suite: 255/255 passed.
• pnpm test: all 29 monorepo test projects passed.
• pnpm --filter @builderbot/provider-baileys build: passed.
• pnpm run generate:check, ESLint, and Prettier checks: passed.

[leifermendez]

Aprobado para el alcance acotado de capturar el rechazo de baileyGenerateImage y emitir un diagnóstico controlado. Verificación del commit revisado: regresión nueva fallando en la producción base, lifecycle 19/19 y provider 255/255 en 8 suites aprobados en el head. Se preserva el require_action con el QR crudo y el comportamiento HTTP existente. Esto no garantiza una imagen válida ni resuelve todas las variantes de imagen ausente de #1253.
