Keep MCAP replay viewers looping and package joint SE3 examples

[jiwenc-nv]

Description

Short recordings could finish before a browser connected. All five MCAP Viser replayers now repeat until Ctrl+C, including Vive SE3 text mode. Remove --loop from existing commands.

Move the joint SE3 live/record/replay modules and helper into isaaccapture_examples.mcap_record_replay so the example wheel includes them. Run them with python -m; default recordings now use ./recordings/ from the working directory. Update usage and docs.

📝 Walkthrough

Walkthrough

The replay examples now repeat playback until Ctrl+C and no longer accept a --loop option. The scripts also remove the post-playback wait that kept the Viser server open. Joint SE3 example commands use Python module paths, and recording defaults and lookup use a recordings directory under the current working directory. Documentation updates reflect these commands and replay behavior.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 4ac98

Replay with nonmatching collections at a zero rate can consume resources until interrupted. This is a bounded example-workflow issue; fix both loops or accept it before merging.

- Around line 221-237: Update the replay loop after the per-collection sample
summaries to stop when no selected collection produced data: check whether any
value in samples is nonzero, report that the recording contains no data, and
break before printing the looping message or creating another ReplaySession.

Review comments at
@examples/mcap_record_replay/python/isaaccapture_examples/mcap_record_replay/replay_se3_vive.py:
- Around line 244-258: In the outer replay loop in replay_se3_vive, check the
per-collection sample counts returned by run_once after each pass; if all values
in samples are zero, report that the recording has no tracker data and break
instead of creating another ReplaySession. Keep looping when any collection has
samples.
