feat(v2): resume limited threads when usage resets

[juliusmarminge]

Limited threads currently require a manual retry after their allowance resets. This layer adds an opt-in environment setting and a per-thread Resume at reset control on web, desktop, and mobile. Web and desktop use the existing composer banner stack, including its warning presentation and action styling.

The server derives schedules from persisted run/reset data and recovery choices. Continuations survive a restart, run without a connected client, and pass through the serialized V2 command path. Cancelled schedules, newer messages, archived or settled threads, replacement errors, changed providers, and pending requests prevent stale deliveries. Expired reset data cannot create a retry loop. Unknown reset times remain manual.

Based on the Limited state port in #12677. The earlier recovery proposal #11215 informed the scope; this implementation uses V2 commands and persisted projections.

Validation: the latest integrated change passes 88 focused tests across three files, including receipt-based recovery scenarios for independent option patches, legacy-client updates, cancelling while snoozed, waking while scheduled, rejecting an expired snooze, and exactly one continuation. Scoped contracts, client-runtime, server, web, and mobile typechecks pass. Scoped lint has no errors; existing mobile purity and server unused-variable warnings remain. Earlier adapter/settings/restart checks also passed. Native mobile was typechecked, not exercised on a device.

The usage-limit banner stays on one row. Button labels show whether automatic resume is enabled.

Summary by CodeRabbit

• New Features

  • Added automatic recovery for threads stopped by usage limits, resuming them at the reported reset time.
  • Added controls to schedule or cancel recovery for individual threads.
  • Added a server setting to enable automatic resumption in web and mobile settings.
  • Added recovery status and reset-time information to thread views and chat banners.

• Bug Fixes

  • Prevented stale or invalid recovery attempts from starting new work.
  • Recovery is canceled when threads receive new messages, are archived, or are settled.

• Documentation

  • Documented usage-limit recovery, automatic resume behavior, and recovery after environment restarts.

Integration verification: current v2 is included. A snooze-raced delivery now receives a fresh recovery identity after waking. The integrated recovery suite passes all 18 scenarios, including duplicate dispatch, rearming, expired and malformed resets, independent choices, and ordinary snooze ownership. Scoped server typecheck and lint pass. A deterministic live client resumed an overdue limit stop exactly once.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a persisted, server-side workflow that automatically resumes usage-limited threads, along with new orchestration commands, settings, and web/mobile controls. It also introduces a new product setting default, so the change requires human review.

No code changes detected at 9eea14d. Prior analysis still applies.

Effect Service Conventions found 2 violations:

• apps/server/src/orchestration-v2/UsageLimitRecoveryService.ts: local Effect services are imported directly instead of through module namespaces.
• apps/server/src/orchestration-v2/runtimeLayer.ts: the recovery layer import is aliased, erasing its owning module namespace.

Inline review comments contain the expected fixes.

This is exactly what I need. I run several threads, and when Claude hits its usage limit, I have to remember to return at 4:40 pm and send "continue" to each one.

Being able to mark individual threads to resume at reset would solve that. Is there a release planned for this? I'm on v0.0.42.
