Fixes sqf_list to combine same multiplicity factors

Agent prompt
what a new run launched now would send
sqf and sqf_list output is not consistant
The example below is wrong in the sense that we should have (x*_2 - 5_x + 6, 3) and not 2 factors of multiplicity 3.
```
> sqf_list( (x**2 + 1) * (x - 1)**2 * (x - 2)**3 * (x - 3)**3 )
> (1, [(x**2 + 1, 1), (x - 1, 2), (x - 3, 3), (x - 2, 3)])
```
whereas below is correct --- one factor of multiplicity 2
```
> sqf_list( x**5 - 2*x**4 - 2*x**3 + 4*x**2 + x - 2 )
> (1, [(x - 2, 1), (x**2 - 1, 2)])
```
Work only inside this repository checkout. Make the code change the task
describes, keeping the diff focused — no drive-by refactors.
When you are done, leave your changes committed or in the working tree;
they are collected automatically.
Stay on this snapshot checkout (`task/ycb_sympy_pr18698`). Never checkout, pull, or rebase onto `main`. That branch is a README-only orphan.
Stay on this HEAD. Do not fetch another default branch. Push only on the Cursor-created `crazy-cursor/…` side branch from this HEAD.
Some past runs of this task were launched with a different prompt (the prompt template changed since, or those runs predate this benchmark's stored prompt). Each run persists the exact prompt it sent at launch — that per-launch record is the audit trail; this page shows only the current one.
