perf(build): skip dts for runtime build profiles

CHANGELOG.md

@@ -54,6 +54,7 @@ Docs: https://docs.openclaw.ai
 - CI/tooling: route script edits through conventional owner tests when matching `test/scripts` or `src/scripts` coverage already exists.
 - CI/tooling: honor option terminators in the memory FD repro script so follow-on arguments are not reparsed.
 - Release/CI/E2E: honor option terminators across release, Parallels smoke, plugin gauntlet, and extension-memory scripts.
+- Performance: skip declaration bundling for runtime-only CLI startup and gateway watch build profiles.
 - Performance: reuse prepared provider handles, strict tool schemas, gateway runtime metadata, session maintenance config, plugin metadata, bundled skill allowlists, package-local plugin artifacts, and single-entry store writes.
