T01.i: bring examples/notebook into the pnpm workspace, fix its type error

pnpm-workspace.yaml listed only packages/*, so pnpm never installed
examples/notebook's dependencies even though root package.json's
workspaces field named examples/* too; the example ran on a stray
node_modules a manual bun install had left behind (symlinks into
node_modules/.bun, including a dangling @ng-eventually/sdk link to a
package that no longer exists). Added examples/* to pnpm-workspace.yaml
and reinstalled; examples/notebook now resolves @ng-org/orm and
@ng-org/web to the exact same pnpm store instances packages/polyfill
uses (verified via the symlinks and node_modules/.pnpm listing) - no
package ended up duplicated.

That alone did not fix the example's TS2345: NoteShape's object
literal had its dataTypes[].valType widened from the "iri"/"string"
literals to plain string (no satisfies clause), which the existing
test suite already guards against elsewhere (satisfies
ShapeType<BaseType>). Applied the same pattern here, importing the
already re-exported ShapeType/BaseType from @ng-eventually/polyfill -
no new dependency needed, no compiler option touched.
