Upgrade outdated three.js code

Models trained on years of three.js write APIs that no longer exist: outputEncoding, sRGBEncoding, Clock, RGBELoader, three/examples/js, useLegacyLights, mergeBufferGeometries. Some throw, some silently change colors or lighting. Find them mechanically, fix the one-to-one renames automatically, and handle the rest by hand.

Paths: <this-skill-dir> is the directory containing this SKILL.md; replace it with that absolute path. The script needs only Node 22+.

Process

1. Run the linter over the project's source (it skips node_modules, build output and minified files):

   node "<this-skill-dir>/scripts/lint.mjs" src
   node "<this-skill-dir>/scripts/lint.mjs" src --json            # for scripting
   node "<this-skill-dir>/scripts/lint.mjs" docs --md             # fenced code blocks in Markdown
