feat(core-shared): bindNoopInstrumentation + bindSentryInstrumentation

Adds DI binder functions for instrumentation. bindNoopInstrumentation binds
NoopTracer + NoopLogger; bindSentryInstrumentation calls initSentryServer then
binds SentryTracer + SentryLogger. Both are idempotent (unbind-first). Adds
inversify + reflect-metadata as devDependencies so container tests compile.
Re-exports from instrumentation barrel. 6 new tests (3+3).
