fix(tui): deliver live events for sessions resumed with -s across directories

What does this PR do?

opencode -s <sessionID> launched from a directory other than the sessions stored directory stops live-rendering: the message list never updates while the agent keeps running in the background. Quitting and reopening the TUI shows the work actually happened.

Root cause: the TUI event stream is scoped by project (event.project === project.project() in context/event.ts), and project.project() is resolved from the launch directory. A session resumed via -s can belong to a different project, so its events are filtered out. The session is still processed server-side; only the TUIs live updates are dropped.

validateSession already fetches the session, so this returns its projectID (no extra request) and threads it through args into the event filter, which now also delivers events whose project matches the resumed session. The working directory is not changed, so -s keeps working from any directory.

How did you verify your code works?

bun test test/cli/tui/use-event.test.tsx (added two cases: delivers the resumed sessions project events from another directory; still ignores unrelated projects) and bun run typecheck in packages/opencode — both green.
