feat: Identify support (OBS + SR)

[abelonogov-ld]

• add before and after identify hooks into Obs and SR
• customerFriendlyName hookup
• user, canonicalUser hookup
• SR identify event
• multi, single, anon user support

---

Note

Adds Identify lifecycle hooks to Observability and Session Replay, propagating user/canonical keys (with optional friendly name) to logs and SR events, plus refactors and an SDK bump.

• Observability:
  • Add Options.contextFriendlyName used when recording Identify.
  • Introduce InternalObserve exposing logClient; Observability stores created service.
  • Replace EvalTracingHook with ObservabilityHook; logs LD.identify after Identify with attributes key, canonicalKey, and identify.result.status.
• Session Replay:
  • Add IdentifyItemPayload (encodes context into attributes) and replace screen payload with ImageItemPayload.
  • SessionReplayEventGenerator emits Custom event with tag Identify; adds Reload payload title from app name.
  • SessionReplayExporter identifies sessions using user attributes (on init and on-demand); stores pending Identify payload.
  • SessionReplayService wires ObservabilityContext, app title (ApplicationProperties.name), and schedules Identify via new SessionReplayHook (after Identify).
  • RRWeb: support CustomDataTag.identify deserialization.
• Common:
  • Add ApplicationProperties.name (reads CFBundleName).
• Dependencies:
  • Bump ios-client-sdk to 10.1.0.
• Test App:
  • Switch to MainMenuView + MainMenuViewModel; add Identify actions (user/multi/anon); set Options.contextFriendlyName in config.

Bug: Hook receives stale options without SDK metadata

The getHooks method passes self.options (the original immutable options) to ObservabilityHook, but Options is a struct. In register, line 19 creates a local copy with var options = options, modifies it with SDK metadata (version, project ID, service name, etc.), and uses that copy for ObservabilityClientFactory.instantiate. However, the modified copy is discarded when register returns. The hook's beforeEvaluation method uses options.resourceAttributes which will be missing all the SDK metadata that was added in register.
