agent: Allow clicking on the read file tool header to jump to the exact file location (#33161)

Release Notes:

- Allow clicking on the header of the read file tool to jump to the
exact file location

When researching code or when the Agent analyzes context by reading
various project files, the read file tool is used. It usually includes
line numbers relevant to the current prompt or task. However, it’s often
frustrating that the read file header isn’t clickable to view the
corresponding code directly. This PR makes the header clickable,
allowing users to jump to the referenced file. If start and end lines
are specified, it will navigate directly to that exact location.
