docs(ai-migration): fix Source of Truth paths; drop dead scss exports

.d.ts types are emitted under dist/types/, not dist/ root. Update the
three affected paths and remove the incorrect .d.cts reference (the SDK
emits .d.ts only). Point at dist/es/ and dist/cjs/ for transpiled JS.

Also remove ./dist/scss/* and ./scss/* from the package.json exports
map — dist/scss/ is no longer emitted, so those exports were dead.
