fix(node): Register diagnostics-channel injection in NodeClient con…

[timfish]

Move registerDiagnosticsChannelInjection() from the Node SDK's init() into the NodeClient constructor, so the injection hooks install for every client, not only the one built by init(). Downstream SDKs that construct a client without going through init() now get channel injection set up for them.

The call keeps its existing guards (the __SENTRY_CHANNEL_INJECTION__ build flag and enableRuntimeChannelInjection: false), read from the constructor's options. Registration is idempotent, so construction on any path stays safe. This follows the same constructor-anchoring pattern already used for _INTERNAL_setDeferSegmentSpanCapture and registerPrepareSpanScope.
