build: enable stricter TypeScript checks

CHANGELOG.md

@@ -6,6 +6,7 @@ Docs: https://docs.openclaw.ai
 
 ### Changes
 
+- TypeScript: enable stricter compiler checks for implicit returns, side-effect imports, overrides, and unused production code.
 - Build: upgrade workspace package management to pnpm 11 and keep Docker, install, update, and release workflows on the pnpm 11 config surface. (#79414) Thanks @altaywtf.
 - Models: add provider-level `localService` startup for on-demand local model servers before OpenAI-compatible requests, including one-shot model probes.
 - Agents: trim default system prompt guidance and send-only message tool schemas to reduce prompt tokens while preserving GPT-5 personality guidance.
