## Title

    Wrap positional-only callables with a keyword-accepting adapter (source-backed, not verified by KFA)

## Body

    Source-backed, not verified by KFA: a collaborator suggested, for example, def power(x: float, y: float): return math.pow(x, y), and registering that wrapper as the tool instead of math.pow directly. They said the tool schema stays the same, so model-facing behavior is unchanged. They asked the reporter to confirm it on real tools, and no confirmation is in the thread. This does not fix the library; the proposed fix, PR #7383, is unmerged and unreleased per the supplied sources (https://github.com/google/adk-python/issues/7382#issuecomment-5996100124).
