[ci] chore: mark nano autoconfig roundtrip as pleasefixme and remove redundant launch script

[cuichenx]

Summary

• Marks TestNemotron3NanoConversion::test_nemotron_3_nano_autoconfig_roundtrip with @pytest.mark.pleasefixme since it is currently broken in the ci environment. THe test runs successfully in the local environment.
• Removes L1_Launch_autoconfig_roundtrip.sh which is redundant — the autoconfig roundtrip tests are already collected by the per-model launch scripts.

Test plan

• Verify CI no longer runs the removed launch script
• Verify the marked test is skipped in CI runs

Summary by CodeRabbit

• Tests
  • Removed an automated test execution script
  • Marked a conversion test to exclude from regular test runs pending fixes

📝 Walkthrough

Walkthrough

A launch script for autoconfig roundtrip tests was deleted, and a test method was marked with a pleasefixme marker to skip it from regular test execution.

605-607: Add a comment explaining why this test is marked pleasefixme.

Other uses of @pytest.mark.pleasefixme in this file include explanatory comments (e.g., # PP=2 broken by hybrid_layer_pattern (PR #2628)). Adding a similar comment here would help future maintainers understand the root cause and when the test can be re-enabled.
