Memory/QMD: add limit arg to search command

CHANGELOG.md

@@ -70,6 +70,7 @@ Docs: https://docs.openclaw.ai
 - Memory/QMD: cap QMD command output buffering to prevent memory exhaustion from pathological `qmd` command output.
 - Memory/QMD: query QMD index using exact docid matches before falling back to prefix lookup for better recall correctness and index efficiency.
 - Memory/QMD: make QMD result JSON parsing resilient to noisy command output by extracting the first JSON array from noisy `stdout`.
+- Memory/QMD: pass result limits to `search`/`vsearch` commands so QMD can cap results earlier.
 - Models/CLI: guard `models status` string trimming paths to prevent crashes from malformed non-string config values. (#16395) Thanks @BinHPdev.
