Add a proxy-side tool emulation layer so Lingma requests can surface stable OpenAI tool_calls and Anthropic tool_use blocks even when upstream tool events are missing or inconsistent.
Constraint: Keep native Lingma tool event bridging as the first path and layer emulation as a fallback
Rejected: Depend exclusively on Lingma native tool/invoke events | tool visibility remains inconsistent across models and transports
Confidence: high
Scope-risk: moderate
Deduplicate allowlist filtering and forced-tool fallback parsing across the OpenAI and Anthropic non-stream bridge paths while preserving existing wire behavior.

Keep the current tool-call bridge contract stable while extracting shared
execution setup and tightening Anthropic forwarding regressions.

Move tool bridge and responses adapter helpers out of app.main so the main entrypoint can shrink without changing route orchestration behavior.
