fix: GH Actions workflows - enforce lint/typecheck, add timeout, fix triggers

- lint.yml: remove || echo so lint errors actually fail the workflow
- typecheck.yml: remove || echo, switch to Bun, add apps/elysia typecheck
- update-submodule.yml: upgrade checkout@v6, add payload validation + push retry
- security.yml: add Rust to CodeQL scan targets
- docker-build-push.yml: remove stale packages/ path refs
- All workflows: add timeout-minutes to prevent stuck jobs
