[codex] Structure relay install confirmation conflicts

[juliusmarminge]

Summary

• replace the concurrent relay install confirmation Error with a Schema tagged error
• capture requested and active versions plus dialog lifecycle and install stage
• keep the state conflict cause-free instead of inventing a synthetic cause

Verification

• vp test apps/web/src/cloud/relayClientInstallDialog.test.ts
• vp check (passes with existing warnings)
• vp run typecheck

Overlap audit

• gh pr list --limit 1000 found no other open PR touching either changed file

Note

Low Risk
Localized dialog-coordinator error typing and messaging; callers that only checked generic Error messages may need to handle the new class.

Overview
Concurrent relay client install confirmation requests now reject with RelayClientInstallConfirmationConflictError (Effect Schema tagged error) instead of a generic Error.

The rejection carries requested vs active version, dialog status (confirming / installing / closing), and install stage when the active flow is installing; closing still resolves the active version from the nested view. A coordinator test asserts the structured fields and that the error has no cause.

Note

Replace generic Error with structured RelayClientInstallConfirmationConflictError for install conflicts

When requestRelayClientInstallConfirmation is called while the dialog is not idle, it now rejects with a new RelayClientInstallConfirmationConflictError instead of a generic Error. The structured error carries requestedVersion, activeVersion, activeDialogStatus, and optionally activeInstallStage, giving callers enough detail to handle conflicts programmatically.

Approvability

Verdict: Approved

This change replaces a generic error with a structured error class for relay client install confirmation conflicts. The control flow is unchanged - only the error reporting is improved with additional context fields. Low risk, self-contained refactor.
