Fix trampoline notebook filename collision#5508

Conversation
Wrapper notebooks were named notebook_<job_key>_<task_key>. Since both keys can contain underscores, distinct pairs like (a_b, c) and (a, b_c) mapped to the same filename and one task silently ran the other task's wrapper. Prefix the job key length to make the name unique per pair. Co-authored-by: Isaac

Why
Found during a full-repo review of the CLI. The python wheel wrapper (trampoline) names its generated notebook
notebook_<job_key>_<task_key>. Both keys can contain underscores, so distinct pairs can produce the same name: joba_bwith taskcand jobawith taskb_cboth map tonotebook_a_b_c. The second wrapper overwrites the first, and both tasks point at the same notebook, so one task silently runs the other task's wrapper.Changes
Before, two different (job key, task key) pairs could collide on one wrapper filename; now every pair gets a unique name. The name is now
notebook_<job_key_length>_<job_key>_<task_key>(inbundle/trampoline/trampoline.go). The length prefix makes the encoding unambiguous for any keys, with no new dependencies. The example above becomesnotebook_3_a_b_cvsnotebook_1_a_b_c.Existing wrapper notebooks get a new path on the next deploy. This only affects bundles with
experimental.python_wheel_wrapper: true, and the wrapper is regenerated and the job spec updated on every deploy, so no action is needed.Test plan
