fix(cli): map --follow to --tail for openshell logs streaming

[senthilr-nv]

Summary

• nemoclaw <name> logs --follow passes --follow to openshell, but openshell expects --tail for live log streaming
• Map the user-facing --follow flag to --tail internally, keeping the CLI interface unchanged
• Update the test to verify the correct flag reaches openshell

This restores the fix from #436 (credit: @paritoshd-nv) which was inadvertently lost during a refactor.

Reproduction (before fix)

$ nemoclaw my-assistant logs --follow
error: unexpected argument '--follow' found
  Command failed (exit 2): openshell logs my-assistant --follow

Test plan

• npm test — 675 passed, 3 skipped
• Manual: nemoclaw my-assistant logs --follow streams live logs (DGX Spark, openshell 0.0.12)
• Manual: nemoclaw my-assistant logs (without --follow) still works

Fixes #1146

Summary by CodeRabbit

• Bug Fixes
  • Fixed log-follow functionality by correcting the CLI argument translation used when retrieving live sandbox logs.

📝 Walkthrough

Walkthrough

sandboxLogs() in bin/nemoclaw.js now appends --tail (not --follow) to the OpenShell CLI args when follow is requested. The corresponding test in test/cli.test.js was updated to expect --tail.

Changes

Cohort / File(s)	Summary
CLI argument correction bin/nemoclaw.js	Replaced appending --follow with --tail inside sandboxLogs() so the constructed args match OpenShell's expected flag.
Test assertion update test/cli.test.js	Updated test description and marker assertion to verify openshell is invoked with logs <name> --tail instead of --follow.

Poem

🐇 I nudged a flag, swapped follow for tail,
One tiny hop and the logs set sail,
Tests winked green, no more fail,
A carrot cheers the little trail! 🥕✨

Superseded by #1187, which absorbed the --follow → --tail fix along with reboot recovery and connect-based registry repair.
