[Bug][runtime] Interrupted tool calls are recorded as tool errors, letting the action loop continue and persist as completed

[Ashfaqbs]

Description

RunnerContextImpl.executeSequentially/executeParallel's tool-call path (ToolCallAction.java:256) catches InterruptedException the same as any ordinary tool failure, records it as a tool error, and lets the action loop continue — unlike the chat-call path (fixed in #1071), which now rethrows a raw InterruptedException immediately.

Concretely, on a cancellation during a tool call:

1. ToolCallAction.java:256 catches the InterruptedException, :257 records it as a tool error.
2. The loop moves on and (:85) sends the ToolResponseEvent anyway, which drives another chat call.
3. ActionExecutionOperator then persists the action as completed (~line 491, durableExecManager.maybePersistTaskResult), since nothing tells it the action was actually interrupted.
4. On recovery, actionState.isCompleted() (~line 437) skips re-execution and replays that stale output instead of re-running the call.

Step 4 is the same failure mode as #1070's "problem 2" (a stale interruption replayed as terminal after recovery), just reached through the action-state persistence path instead of the durable-call-slot path that #1071 closed for the chat side — because here the raw InterruptedException never escapes far enough to skip the persist call.

executeParallel has the equivalent shape at RunnerContextImpl.java:209 (parallel tool call execution added in #926).

This predates #1071 and is out of that PR's scope (chat-call retry/persistence only); filing separately per discussion on #1071 (comment) and follow-up at #1071 (comment).

Expected behavior

A cancellation during a tool call should propagate the same way the chat-call fix in #1071 does: restore the interrupt flag and rethrow immediately, rather than being recorded as a tool error and let the action loop continue — so the action is never persisted as completed off the back of a cancelled tool call, and recovery re-executes rather than replaying stale output.
