🚏 feat: Central Trace Destination Opt-Out for Langfuse (#14838)
* feat(langfuse): let callers opt out of the central trace destination

Adds `centralTraceExportEnabled` to the score-destination options and threads
it through `getScoreDestinations`, `getLangfuseTraceDestinationIds` and
`getLangfuseTraceMessageFields`.

Deployments that route traces per tenant may want a given turn's spans to reach
only the tenant destination — for example when central export is a per-tenant
setting rather than a deployment-wide one. Today the central project is included
whenever env credentials exist, with no way for a caller to decline it for a
single trace.

Defaults to `true` everywhere, so existing callers are unaffected: the option is
additive and every current call site resolves exactly as before. The three
public helpers gain an optional trailing parameter and nothing else.

While here, `getScoreDestinations` destructures its options with defaults
instead of repeating `options?.waitForCentralProjectId !== false` at both call
sites, which is what made adding a second flag awkward.

Verified: no new tsc errors (one pre-existing cacheFactory error is unchanged),
99 langfuse tests pass, ESLint and Prettier clean.

* fix(langfuse): keep the central opt-out intact when destinations resolve

Addresses two review findings on the new `centralTraceExportEnabled` option.
Both are cases where opting out of central export was silently discarded by
destination resolution, letting later feedback reach a project the trace never
went to.

1. Non-fanout deployments with no central env credentials still returned the
   configured connection, because only the central-credential branch was gated.
   `resolveLangfuseExportPlan` reports `disabled` for that shape — without a
   fanout route there is nowhere for a central-suppressed trace to go — so
   return no destinations and match it.

2. `getLangfuseTraceDestinationIds` returned `undefined` whenever any
   destination lacked an id, and `sendFeedbackScore` reads `undefined` as
   unrestricted. A tenant destination has no id when its optional `projectId`
   is unset, so a suppressed-central trace could resolve back to the central
   project at feedback time. Fail closed with an empty list, which stays
   restricted, instead.

Both paths now have regression tests, each verified to fail without the
corresponding change: the first returned 3 destination ids, the second returned
`undefined`.

* fix(langfuse): carry the central opt-out into the feedback path

`getLangfuseTraceDestinationIds` returns `undefined` when an eligible
destination has no stable id, which a tenant route hits whenever the
optional `langfuse.projectId` is unset. `sendFeedbackScore` read that as
"unrestricted" and re-resolved destinations with central export enabled,
so a suppressed-central trace still drew central feedback.

Persisting an empty list instead only traded the leak for a drop: the
destination filter rejects every id-less destination, discarding ratings
the tenant should receive. The id list restricts feedback to destinations
that survived reconfiguration; it cannot also encode deployment policy.

Thread `centralTraceExportEnabled` through `sendFeedbackScore` so the
policy is evaluated the same way at trace time and feedback time, and
restore `undefined` for unidentifiable destinations.

🚀 What's New in v0.8.8-rc1

  • Agent run control: Interrupt or steer an Agent mid-run, queue follow-up messages, and reclaim, edit, or escalate pending steers.
  • Human-in-the-loop Agents: Agents stream question progress, ask up to four related questions in one form, pause for input or tool approval, and resume.
  • Unified Agent Builder: A redesigned Tools marketplace brings together Skills, MCP, Code Interpreter, orchestration, Programmatic Tool Calling, model-spec controls, and per-tool background and intent settings.
  • Readable Agent activity: Generated activity-group headers, parent phase summaries, and live tool intent labels make long reasoning and tool runs easier to scan.
  • Code Interpreter workflows: Code and shell tools can run in the background, sandbox images return as viewable artifacts, and highly experimental stateful sessions can reuse prewarmed conversation workspaces.
  • Agent extensibility: Experimental Agent Plugins can bundle deployment Skills, MCP servers, and opt-in command hooks, while explicit subagents initialize only when selected.
  • Memory, context, and identity: Agents can manage memory with optional per-agent isolation, expose support contacts safely, and show a more faithful Context Usage gauge.
  • Sharing and files: Shared conversations show a badge and update at a stable URL, while signed-in viewers can continue them as personal copies.
  • Artifact workflows: Open previews fullscreen, work with PowerPoint .potx templates across upload, search, and code execution, upload shell scripts across common MIME variants, export Mermaid diagrams as SVG or PNG, and download original Office files from the artifact panel.
  • Models and reasoning: Added GPT-5.6 with Responses API reasoning controls, Claude Opus 5 and Sonnet 5, Gemini 3.7 and 3.6 Flash, and Gemini 3.5 Flash-Lite.
  • Langfuse observability: Configure encrypted Langfuse connections in-app, let authorized admins open sampled sessions directly, optionally fan out traces by tenant, and suppress central export per run.
  • Administration and security: Delegate config sections, encrypt registered secrets, enforce SSRF checks for speech, OCR, and web tools, and generate unique temporary credentials when secrets are blank.
  • Messages and navigation: Right-aligned user turns, unified multi-part editing, full-message copy, a dock-style message rail, virtualized search, smooth streaming, and faster Agent startup.
  • Streaming and tool reliability: Adaptive provider smoothing, Redis delta batching, dynamic MCP tool refresh, parsed MCP response media types, runtime OAuth recovery, and Agent stream circuit breakers improve long-running workflows.
  • Deployment and reliability: Added configurable HTTP timeouts, Amazon DocumentDB 5.0+ support, low-noise Redis and browser observability, and a rolling-upgrade-safe generation protocol.
