Fix OpenCode event session routing

[samjandris]

Summary

• switch OpenCode runtime events from the now-empty /event stream to /global/event
• unwrap global event payloads for the active session directory before using the existing provider event projection
• add regression coverage that the adapter uses the global event stream and handles wrapped OpenCode message events

Fixes #2633

Test plan

• bun fmt
• bun lint
• bun typecheck
• bun run --cwd apps/server test src/provider/Layers/OpenCodeAdapter.test.ts

---

Note

Medium Risk
Changes how OpenCode runtime events are consumed and filtered (switching to global.event and dropping non-matching directories), which could affect event delivery/completion semantics across sessions if the upstream event shape differs.

Overview
Routes OpenCode runtime event consumption from the per-session event.subscribe stream to client.global.event, and updates the adapter to unwrap payload and ignore events not matching the session directory before projecting provider runtime events.

Updates the event type aliasing to reflect the wrapped global-event shape, and extends the test double + adds a regression test that enforces use of global.event (throwing if event.subscribe is called) and validates content.delta emission from wrapped message events for the correct session directory.

Note

Fix OpenCode event session routing by filtering global events by directory

• Switches the event subscription in OpenCodeAdapter.ts from client.event.subscribe to client.global.event, which emits events for all directories.
• Adds directory-based filtering so only events whose directory matches the session's working directory are forwarded to the event handler.
• Updates the OpenCodeSubscribedEvent type alias to extract the payload field from global events, resolving to never for events without a payload.
• Test doubles in OpenCodeAdapter.test.ts are updated to simulate long-lived, abortable global event streams and assert directory-scoped filtering behavior.
• Behavioral Change: event.subscribe is no longer used; the adapter now receives all directory events globally and filters client-side.
