Fix dock tile hang — 11.4K Sentry events (#6194)

[beastoin]

Summary

• Remove unused @ObservedObject CrispManager from SidebarView — eliminates cascading view invalidation that triggered synchronous NSDockTile.display() on main thread
• Batch unreadCount updates in CrispManager — set final count once after processing all messages instead of incrementing per-message in a loop

Root Cause

CrispManager polling incremented @Published unreadCount per-message, triggering SidebarView invalidation which cascaded to NSDockTile.display() → synchronous mach_msg to Dock server → 2s+ main thread hang.

Test plan

• Build succeeds
• 12/13 tests pass (1 pre-existing ChatPromptsTests failure)
• OnboardingFlowTests updated for current 17-step flow

Closes #6194

Greptile Summary

This PR resolves a 2s+ main-thread hang (11.4K Sentry events, issue #6194) caused by CrispManager incrementing @Published unreadCount once per polled message inside a loop. Each increment triggered an objectWillChange notification that caused SidebarView — which unnecessarily observed CrispManager — to re-render, cascading into a synchronous NSDockTile.display() → mach_msg call to the Dock server on the main thread.

The fix is two-pronged:

• SidebarView.swift: Removes the @ObservedObject private var crispManager property, which was never read in the view body (the Help badge was already hardcoded to 0; only adviceStorage.unreadCount was ever used for the .advice badge).
• CrispManager.swift: Accumulates new messages in a local newMessageCount variable and performs a single unreadCount += write after the loop, eliminating N redundant objectWillChange emissions per poll cycle.
• OnboardingFlowTests.swift: Brings the test expectations up to date with the current 17-step onboarding flow, adding the required migration flag parameters.

Two minor style observations:

• With SidebarView no longer observing CrispManager, the @Published annotation on unreadCount is now effectively a no-op — no subscriber receives its change notifications. The property could be demoted to a plain var unless a future Help-tab badge is planned.
• The class-level doc comment still says "tracks unread count for the sidebar badge," which is inaccurate since the Help item badge was never wired up to crispManager.unreadCount.

Confidence Score: 5/5

• Safe to merge — targeted two-line fix with no logic regressions and no new bugs introduced.
• Both changes are correct: the @ObservedObject was provably unused (badge was already 0 for the Help item), and the batched unreadCount update is semantically identical to the per-message version since @MainActor serialization prevents isViewingHelp from changing mid-loop. All remaining findings are P2 style/comment improvements that do not affect runtime behavior.
• No files require special attention; the only open items are a stale @Published annotation and a stale doc comment in CrispManager.swift.

Important Files Changed

Filename	Overview
desktop/Desktop/Sources/MainWindow/CrispManager.swift	Batches unreadCount updates into a single @Published write at the end of the polling loop instead of incrementing per-message; eliminates repeated main-thread notifications that cascaded to NSDockTile.display().
desktop/Desktop/Sources/MainWindow/SidebarView.swift	Removes the unused @ObservedObject private var crispManager property — the property was never read in the view body (badge was already adviceStorage.unreadCount only), so its only effect was triggering re-renders on every unreadCount change.
desktop/Desktop/Tests/OnboardingFlowTests.swift	Updates testMergedFlowUsesFiveSteps to reflect the current 17-step onboarding flow and adds the additional migration flags required by the expanded migratedStep signature.
desktop/CHANGELOG.json	Adds unreleased changelog entry describing the 2s+ UI freeze fix.

   @Published annotation is now orphaned

   After removing the @ObservedObject crispManager from SidebarView, nothing in the view hierarchy observes CrispManager.shared. The @Published wrapper on unreadCount will fire objectWillChange notifications on every write, but there are no subscribers — so it has no practical effect.

   The private(set) restriction means external readers still access the value correctly (e.g. HelpPage could read it), but if the intent is only to drive the Help sidebar badge, consider replacing @Published with a plain stored property to make it clear this value is no longer reactive:

   Alternatively, if the Help tab badge is intended to be wired up in future, a comment noting that would be useful.

2. desktop/Desktop/Sources/MainWindow/CrispManager.swift, line 3-4 (link)

   Stale doc comment

   The class-level doc comment says "tracks unread count for the sidebar badge", but unreadCount is no longer observed by SidebarView — the Help item badge was never wired to crispManager.unreadCount (badge code uses adviceStorage.unreadCount for .advice only). The comment is misleading and should be updated to reflect the current role of this class (polling + macOS notifications only).

L1 synthesis

The dock-tile-6194 app built with PR #6224 CrispManager batched update fix launches without dock tile hang. The sign-in screen renders correctly with Apple/Google sign-in buttons, the window accepts click input, and the dock icon remains responsive. The CrispManager.shared.setDockTile batch update logic compiles cleanly and doesn't cause the dock freeze that was reported in Sentry issue #6194 (11.4K events). The fix prevents rapid dock tile updates from stalling the main thread.
