test(plugin-dev): alias @objectstack/setup and @objectstack/account to source in the vitest config

check:test-source-alias reds on the literal specifiers: dev-plugin.ts now
names both packages statically, and unaliased they resolve through
exports to dist/, so a test verdict would depend on build state. Two
anchored entries, exactly as the gate prescribes; both packages' own
imports (platform-objects/apps, spec/system) are already aliased. Every
suite mocks both packages, and the mocks resolve through the same
entries: the full suite stays green and the six-init probe still shows
zero main-process requests in the test phase.
