Ramnique Singh 15567cd1dd let tool failures be observed by the model instead of killing the run
streamAgent executed tools with no try/catch around the call. A throw
from execTool or from a subflow agent streamed up through streamAgent,
out of trigger's inner catch (which rethrows non-abort errors), and
into the new top-level catch that the previous commit added. That
surfaces the failure — but it ends the run. One misbehaving tool took
down the whole conversation.

Wrap the tool-execution block in a try/catch. On abort, rethrow so the
existing AbortError path still fires. On any other error, convert the
exception into a tool-result payload ({ success: false, error, toolName })
and keep going. The model then sees a tool-result message saying the
tool failed with a specific message and can apologize, retry with
different arguments, pick a different tool, or explain to the user —
the normal recovery moves it already knows how to make.

No change to happy-path tool execution, no change to abort handling,
no change to subflow agent semantics (subflows that themselves error
are treated identically to regular tool errors at the call site).
