refresh the version table and expected lines on the current packages (parts 1.42.0 / rig-c 2.64.1 / pose 0.36.0) #8

Why

The site's Getting Started clips (rig-c.github.io#38) were recorded from a clean walkthrough on parts 1.42.0 / rig-c 2.64.1 / pose 0.36.0 / play 1.12.0; the guide's own version table (docs/REFERENCE.md and the README table) still says 1.41.1 / 2.61.1 / 0.35.0 from the 2026-10-20 run #7.

What

Re-run the README's sh blocks clean on the current versions (the #7 procedure), refresh the version table and any expected line that moved, nothing else.

Bars

1. Clean run 10/10 with the verbatim command and wall clock in the PR.
2. Every expected line byte-exact; versions from npm view.
