Fixes#73502.
Active Memory now allows its hidden recall sub-agent to use both bundled memory tool contracts: memory_recall for memory-lancedb and memory_search/memory_get for memory-core. The prompt prefers memory_recall when available and falls back to the legacy tool pair when that is the active backend surface.
Also updates Active Memory docs, QA mock fixtures, and debug parsing compatibility for the two recall paths.
