mantrakp04 f4c2ee4575 feat(analytics): cross-tier span propagation (client fetch header + server withSpan({ request }))
Auto-links a customer's BACKEND span to the caller's CLIENT session with zero glue.
The browser attaches one `x-hexclave-span-context` header to same-origin outgoing
fetches; `serverApp.withSpan(type, { request }, fn)` resolves the caller's refresh
token (from the session) plus that header, so the span — and everything created
inside the callback — parents under $refresh-token → $session-replay →
$session-replay-segment, exactly like a browser event.

- span-propagation.ts: versioned base64url header codec, same-origin fetch
  auto-wrapper (idempotent, native header semantics preserved), origin predicate
- server-request-context.ts: AsyncLocalStorage ambient request context
- server-app-impl: withSpan/trackEvent({ request }) resolution; server telemetry
  buffer re-keyed from userId to the full (user, refresh, replay, segment) context;
  propagated custom parents flow as ambient frames
- backend events/batch: accept forwarded refresh_token_id/session_replay_id on
  SERVER auth (rejected on client auth); compose [rti-,sri-,srsi-,cs-] + stamp
  the scalar columns
- client-app-impl: install the fetch wrapper on init behind analytics.spanPropagation
  (same-origin default + exact-origin allowlist); reads the live per-tab id
- tests: 24 propagation unit tests + 2 e2e (server-auth ancestry + client-auth reject)

The framework adapters (tRPC, Convex, oRPC, ElysiaJS) build on this primitive in a
separate stacked branch; with an adapter you never pass { request } yourself.
