create_timer throws but isn't documented to throw

[Ryanf55]

Operating System:

Ubuntu 24

ROS version or commit hash:

Jazzy

RMW implementation (if applicable):

fastrtps

RMW Configuration (if applicable):

N/A

Client library (if applicable):

rclcpp

'ros2 doctor --report' output

N/A - it's proprietary

Steps to reproduce issue

1. Create a node, and add a (while/for) loop call that blocks while rclcpp::ok() is true
2. Trigger a ctrl+C on the node which now means that rclcpp::ok() is false
3. Later in code execution, call create_timer(..
4. Observe the timer creation fail and throw
5. Observe a non-zero exit code from the node

Expected behavior

If exceptions are throw, they are documented in the header. Alternatively, create_timer could return nullptr and catch the exception.

Actual behavior

This exception is not documented

Here's the backtrace.

If you need a minimum reproducible example, I can help provide one, but I haven't spent the time to write one yet.
