Platform CI/CD

Workflows in .gitea/workflows/ are runtime-agnostic — they read .platform/config.yaml at run-time to determine build toolchain, container port, and health endpoint. No workflow files need updating when this service is migrated to a different runtime.

Config key	Value
`runtime`	`typescript-nestjs`
`health_path`	`/health`
`container_port`	`3000`
