[codex] Preserve desktop update state read failures

[juliusmarminge]

Summary

• replace the silent initial desktop update state fallback with a structured Schema error
• retain the exact bridge rejection cause and final retry count
• recover through tagged catch semantics so the update event listener remains active
• verify retries, structured logging, cause forwarding, and listener recovery

Validation

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

Note

Low Risk
Localized desktop update atom bootstrap and logging; behavior on success is unchanged and failure still falls back to null while keeping the listener active.

Overview
Replaces the silent initial getUpdateState failure path in createDesktopUpdateStateAtom with a DesktopUpdateStateReadError tagged error, three retries, and Effect.logError using structured fields (errorTag, attemptCount, stack) before continuing with null so the update listener stays subscribed.

Tests add afterEach mock restoration and assert three bridge read attempts, the exact log message, and that logged context does not leak raw error/cause payloads while later events still update atom state.

Note

Log errors when desktop update state read fails after 3 attempts

• Wraps the initial desktop update state fetch in Effect.tryPromise, retrying up to 3 times (via INITIAL_STATE_READ_ATTEMPT_COUNT) before falling back to a null initial state.
• Introduces DesktopUpdateStateReadError, a tagged error class that captures attemptCount and cause, replacing the previous silent orElseSucceed(null) fallback.
• On final failure, logs the error tag, attempt count, and stack before proceeding, making read failures observable.
• Adds test coverage in desktopUpdate.test.ts asserting the retry count, error shape, and logged context structure.

Approvability

Verdict: Approved

This PR adds error logging for desktop update state read failures without changing runtime behavior - failures still result in null being returned, but now with structured error logging. The changes are self-contained and well-tested.
