fix(clients): hide duplicate Cursor Keychain prompts

[Yash-Singh1]

What Changed

Hide the Cursor Keychain access prompt when any selected environment already reports Cursor account usage. Show environments running an incompatible older server as excluded from usage totals, and simplify usage contract decoding.

Why

Enabling Cursor account usage in one environment reports that account's history across machines, so prompts on other environments are redundant. The usage page now describes version-skewed coverage in terms of older servers excluded from totals.

UI Changes

Updated usage notices in web and mobile, and combined reconnect and version notices while an environment restarts during an update.

Checklist

• This PR is small and focused
• I explained what changed and why
• I included before/after screenshots for any UI changes
• I included a video for animation/interaction changes

Summary by CodeRabbit

• Bug Fixes
  • Cursor Keychain prompts now account for Cursor account information found in any selected environment, avoiding unnecessary prompts. When no account information is found, only environments that need Keychain access are included.
  • Keychain access requests now time out if a prompt goes unanswered and provide guidance to allow access and refresh. A later request can reuse the pending read, so it won’t start another prompt.

📝 Walkthrough

Walkthrough

The change adds a shared helper that checks usage summaries before selecting environments for Cursor Keychain access. The mobile and web usage screens use this helper. The server credential reader adds a timeout for Keychain reads, and the usage reader returns specific guidance when a read times out.

Changes

Cursor Keychain Access

Layer / File(s)	Summary
Shared access filter and screen integration packages/client-runtime/src/state/usage.ts, packages/client-runtime/src/state/usage.test.ts, apps/mobile/src/features/usage/UsageRouteScreen.tsx, apps/web/src/components/usage/UsagePage.tsx	The helper returns no environments if a usage summary contains a Cursor account source. Otherwise, it returns environments marked as needing Cursor Keychain access. Tests cover both outcomes. The mobile and web usage screens use the helper.
Credential timeout and usage error handling apps/server/src/provider/cursorCredentialStore.ts, apps/server/src/provider/cursorCredentialStore.test.ts, apps/server/src/usage/cursorUsageReader.ts, apps/server/src/usage/cursorUsageReader.test.ts	The credential reader rejects a caller with CursorKeychainTimeoutError after the timeout, while leaving the pending read available for reuse. The usage reader returns Keychain-access guidance for timeout errors and retains the generic message for other Keychain failures. Tests cover timeout handling and read reuse.

Merge Risk: 🔵 Low · up to ae9fd

Unanswered Keychain prompts can gradually increase server memory use during repeated checks. The change is mergeable with a bounded follow-up to remove timed-out waiters.
