Fix repeated steering and reliable stop

[Quicksaver]

Summary

Allow users to send consecutive steering prompts while a conversation is running and reliably stop the active Codex turn after any number of steers. Steering dispatches clear as soon as the server projects the exact submitted user message, while root interruption resolves the provider's live active turn instead of relying on potentially stale projected state.

Explicit child-turn interruptions continue to target the requested child directly. Root lookup is bounded and failure-tolerant: failed or timed-out reads fall back to the cached active turn, while a successful read with no active turn suppresses a stale interrupt.

The workspace configuration also enables pnpm's global virtual store and makes the prerelease @effect/vitest package extension resolve vite-plus consistently.

What Changed

• Track the expected user-message id for each local dispatch and acknowledge only that exact projected message.
• Wire generated message ids through new-thread, follow-up, and in-turn steering send paths so the composer can re-enable after an acknowledged steer without waiting for a turn or session transition.
• Resolve root Codex interruptions from a live thread/read request with turns included, selecting the newest in-progress turn by timestamp and falling back to provider response order when timestamps are absent.
• Honor explicitly requested child turn ids directly without performing root active-turn lookup or fallback.
• Bound active-turn lookup time, log lookup failures, and fall back to the cached session turn only when the lookup fails.
• Suppress stale interrupts when a successful live lookup reports no active turn.
• Add focused regression coverage for consecutive steering, exact-message acknowledgement, timestamp and response-order turn selection, timeout and failure fallback, and successful empty live reads.
• Enable pnpm's global virtual store, correct the prerelease @effect/vitest package extension, and refresh the lockfile.

Why

Running conversations could leave the composer busy after steering because acknowledgement depended on turn or session transitions that do not occur for an in-turn steer. After steering, stop could also target a stale cached turn rather than the provider's actual active turn. Together, these behaviors prevented repeated steering and made interruption unreliable precisely when users needed it most.

The pnpm workspace update keeps dependency resolution stable across worktrees and ensures the patched Effect Vitest package receives the runtime dependency it imports.

Validation

• pnpm exec vp test apps/web/src/components/ChatView.logic.test.ts apps/server/src/provider/Layers/CodexInterruptResolution.test.ts apps/server/src/orchestration/Layers/ProviderCommandReactor.test.ts (67 tests passed)

Proof

• Automated regression coverage in the changed web and server test suites.

Note

Medium Risk
Touches live Codex interrupt resolution and composer dispatch acknowledgement in running sessions; behavior changes are covered by new tests but affect stop/steer UX on critical paths.

Overview
Improves in-turn steering and Codex stop so the composer and interrupt path stay aligned with what the server actually has.

Web: Local “sending” state now keys off an expectedUserMessageId for each dispatch instead of treating any new projected user message as acknowledgement. beginLocalDispatch runs after newMessageId() so the snapshot matches the outgoing message. While the session is running, acknowledgement clears only when that exact id appears in projected messages—supporting consecutive steers without waiting for a new turn, and ignoring unrelated user messages (e.g. another client).

Server: Root interruptTurn resolves the target via resolveCodexInterruptTurnId: live thread/read with includeTurns: true, pick the newest inProgress turn (timestamps, else provider order), 2s timeout, fallback to session activeTurnId only on lookup failure. A successful read with no active turn does not reuse a stale cached id. Explicit turnId still wins for child interrupts.

Also adds BRANCH_DETAILS.md, dedicated interrupt tests, migrates CodexSessionRuntime.test.ts to @effect/vitest, and tweaks pnpm (global virtual store, @effect/vitest / vite-plus resolution).

Note

Fix repeated steering and reliable stop by improving interrupt resolution and steer acknowledgement

• Adds resolveCodexInterruptTurnId in CodexSessionRuntime.ts to perform a live provider thread read (with a 2-second timeout) to find the most recent in-progress turn before interrupting, falling back to the session's projected active turn only on failure or timeout.
• Fixes steer acknowledgement in ChatView.logic.ts by tracking an exact expected user message id (expectedUserMessageId) instead of detecting any change to the latest user message, preventing premature or spurious acknowledgement of consecutive steers.
• Updates ChatView.tsx so beginLocalDispatch is called only after the new message id is created, ensuring the composer waits for the server to project the exact expected id.
• Behavioral Change: a successful interrupt lookup that finds no active turn now returns undefined instead of falling back to the stale session turn id.
