fix(eve): emit turn epilogue when parking for connection authorization in conversation mode (#1525)

[iroiro147]

Summary

Fixes #1525. A conversation-mode turn that parks on connection authorization never emitted a turn boundary: authorization.required went out on the session stream, but no turn.completed / session.waiting followed. useEveAgent clients derive turn status exclusively from a boundary event, so the chat UI spun on "Thinking…" forever, no continuation token reached the client, and cancel could not resolve.

Root cause

packages/eve/src/harness/tool-loop.ts — the two park branches were asymmetric:

• Input-request park (pending input batch) emits the input-requested event and then, in conversation mode, calls emitTurnEpilogue (which emits turn.completed and session.waiting with the continuation token) before returning.
• Authorization park (findAuthorizationSignalFromToolResults hit) emitted authorization.required per challenge and returned the parked session without calling emitTurnEpilogue.

Channel sessions do not need the boundary, and input-request parks (approvals) work everywhere — which is why only conversation-mode surfaces hung.

Fix

Mirror the input-request branch in the authorization park:

if (config.mode === "conversation") {
  emissionState = await emitTurnEpilogue(
    emit,
    emissionState,
    config.mode,
    parkedSession.continuationToken,
  );
  parkedSession = setHarnessEmissionState(parkedSession, emissionState);
}

Task and channel sessions are unchanged.

Behavior

Stream events after this change (conversation-mode auth park):

session.started
turn.started
message.received
step.started
actions.requested
step.completed
authorization.required
turn.completed        ← new
session.waiting       ← new (carries the continuation token)

The connect card renders immediately, the turn settles, cancel resolves, and resumed sessions behave — matching the end-to-end verification recorded on the issue.

Tests

• Extended the existing conversation-mode auth-park test in packages/eve/src/harness/tool-loop.test.ts with a regression assertion proving turn.completed and session.waiting follow authorization.required and carry the session continuation token.
• packages/eve typecheck: clean.
• Full src/harness unit suite: 45 files / 694 tests passing.

Verification

cd packages/eve && pnpm exec tsc -p tsconfig.json --noEmit && pnpm exec vitest run --config vitest.unit.config.ts src/harness
