Install with pnpm, as the sibling branch does

bun install does not rewrite what is already in node_modules when a version
goes DOWN, which silently left @ng-org/orm and @ng-org/web on versions that
disagree about orm_start_graph's arity — the callback then lands in the config
slot and the SDK rejects it as unserializable. Every dependency measurement
taken this way was meaningless.

Carried over from ng-eventually with it: cucumber invoked through the package
entry rather than the .bin shim, which node --import tsx/esm cannot load under
pnpm; the build:orm paths, which still pointed at a src/shapes that moved to
src/shared/shapes; and the tsconfig fix that DROPS baseUrl instead of silencing
its deprecation — reported as a config error, it made tsc exit without checking
a single file.
