Update Kineto Submodule

Update the `third_party/kineto` submodule in a local PyTorch repo to point to a commit from this Kineto repo.

If a commit hash is provided via `$ARGUMENTS`, use that as the target hash. Otherwise, use the tip of main from this repo.

Prerequisites

Before starting, you need the path to the local PyTorch repo. If you do not already know it from prior conversation context, ask the user:

> "What is the path to your local PyTorch repo?"

The PyTorch repo is required — do not proceed without it. Store the path as `$PYTORCH` for the steps below.

Steps

1. **(PyTorch) Get the current submodule hash:**

   cd $PYTORCH && git submodule status third_party/kineto | awk '{print $1}' | sed 's/^[-+]//'

2. **(Kineto) Get the target hash.** If `$ARGUMENTS` is provided, use it. Otherwise, get the tip of main from this repo:

   git log -1 --format='%H' main

Do NOT fetch or pull from remote -- you do not have permissions. The repo is already up to date.

3. **(PyTorch) Create a branch** named `release_YYYY_MM_DD_<short_new_hash>` (using today's date and the short target commit hash) and switch to it.

4. **(Kineto) List included commits** between old and new hash:

   git log --format='- %s %h' <old_hash>..<new_hash> | sed 's/(#/(pytorch\/kineto#/g'

5. **(PyTorch) Update the submodule** to the new hash. The submodule's local object store likely won't have the target commit, so fetch from the local Kineto repo first:

   cd $PYTORCH/third_party/kineto && git fetch <path_to_kineto_repo> main && git checkout <new_hash>

6. **(PyTorch) Commit** with a message in this format:

   Update third_party/kineto submodule to <short_new_hash>

   Includes the following commits:

   - <message1> <hash1>
   - <message2> <hash2>
   - ...

If the current hash already matches the target, inform the user that kineto is already up to date and stop.
