fix: wire El imports, fix runtime API calls, build passes

- forge.el: add import statements for schema/probe/compiler/install
- All files: arg(n)/arg_count() → get(args(),n)/len(args())
- compiler.el: llm_call_system (utility cap violation) → http_post_with_headers
- install.el: http_post_auth_json → http_post_json (_auth already in body)
- Makefile: local dev build using installed El SDK
- .gitea/workflows/forge-release.yaml: CI build on push + el-sdk-updated dispatch
- dist/forge: builds and runs
