fix(detector): detect partial storage replay

[prasannakotyal]

KernelGuard-Red-Submission: 178

Detects functools.partial entrypoints that bind a mutable storage argument and replay from that storage on later calls.

The pass requires:

• module-level custom_kernel = partial(function, <mutable>)
• a no-compute fast path in the target function that does not depend on live input
• fast-path return by subscript from the bound mutable argument
• mutation of that same bound argument inside the target function

Local validation:

• uv run python -m py_compile kernelguard.py
• uv run python /home/nino/repos/paradigma/kernelguard_bypasses/eval_blue_patch.py /home/nino/repos/paradigma/competition_state/kernelguard_mirror/kernelguard.py

Target red fixture: red_59_partial_storage_replay.py

Thanks for the KernelGuard Flywheel Campaign contribution. This PR is now superseded by the consolidated rule-family implementation in #273, which folds this detector coverage together with the related passing-eval variants.
