[Bug]: [Resolver] Multi-line GitHub comments break the macro

[enyst]

Is there an existing issue for the same bug?

• I have checked the existing issues.

Describe the bug and reproduction steps

It appears that the @openhands-agent tagging doesn't always work, the bash conditions are unhappy when the GitHub comment is multiline with random complex stuff in it.
Example: https://github.com/All-Hands-AI/OpenHands/actions/runs/11989779372/job/33426535798#step:9:2

Maybe we can restructure it into a variable first?
