[None][ci] waive pre-existing test failures on main

[brnguyen2]

Waives for pre-existing test failures on main, each with a filed tracking bug. These failures block unrelated PRs; landing the waives here keeps them out of those PRs' diffs.

Test	Tracking bug	Blocked PR(s)
kv_cache/test_kv_cache_v2_scheduler.py::TestKVCacheV2LoRA::test_lora_chunked_prefill	https://nvbugs/6640875	#17975
examples/visual_gen/test_visual_gen_ltx2.py::test_ltx2_example	https://nvbugs/6641122	#17993

Maintained by pr-babysitter: entries are pruned automatically as main picks their tests up, and the PR closes itself when nothing is left to carry. The branch is regenerated on each change — do not push to it.

Dev Engineer Review

• Added waivers for:
  • examples/visual_gen/test_visual_gen_ltx2.py::test_ltx2_example, linked to NV bug 6641122.
  • kv_cache/test_kv_cache_v2_scheduler.py::TestKVCacheV2LoRA::test_lora_chunked_prefill, linked to NV bug 6640875.
• The waiver entries use valid test paths and bug references.
• No duplicate waiver was found.
• No code, API, or public entity changes were made.
• The waivers target known failures and do not expand test scope.

QA Engineer Review

• Modified tests/integration/test_lists/waives.txt.
• Added two waiver entries.
• No test-db/ or qa/ files were modified.
• No test functions were added, modified, or removed.
• CBTS coverage data is unavailable for this test-list-only change.
• Verdict: needs follow-up.
