refactor(service-graph): eagerly construct leaf services in init()

Moves skill, budget-enforcement, and session-management service
construction to the top of service-graph init(), so the three
getOrCreate* getters are pure readers that throw if called before
init. This also fixes a duplicate-allocation bug in the orchestration
listRuntimeSkillEntries closure, which was building a second
SkillService instance instead of reusing the shared one.

The outer getOrCreate* API surface stays intact for
main-runtime-support.ts callers. The teardown setTimeout(app.exit,
3000) is left in place because worker CLI child processes keep the
event loop alive; replacing it needs a full Disposable chain refactor
that conflicts with in-progress pi-runtime integration work.
