Let "effort=max" in an @claude comment or new issue opt into max effort

Claude runs at max effort only when a comment starts with
"@claude /pr-review". Every other request, such as a question, an
investigation or a code change, runs at the default effort, and there is
no way to ask for more.

Now a comment that contains "effort=max", or a new issue whose body
contains it, also runs at max effort, as in pytorch/pytorch. For reviews
this adds nothing new: every review request already goes through the
/pr-review skill, so "@claude review effort=max" runs the same as
"@claude /pr-review". The new effect is on requests that are not reviews.

The issue body is read only on issue events. On a comment it holds the
issue or PR description, so a description that mentions effort=max would
otherwise raise every comment there to max effort.

Max effort stays opt-in because it is slow. In recent runs on this
repository, max effort reviews took 14 to 58 minutes, against 4 to 8 at
the default. The job is stopped after one hour, when its credentials
expire, and a run stopped there loses any answer it has not posted yet.
