feat: vendor gesture-control source into packages/gesture-control

Bring the Ark0N/codeman-gesture-control repo in-tree as the codeman-gesture-control
workspace package so the hand-tracking overlay can be developed in the Codeman repo.
New npm run build:gesture bundles src/codeman/entry.ts into the served
gesture-codeman.js; scripts/build.mjs reruns it on every production build.
Source formatted to Codeman's prettier style.
