feat(inbox): gate signals inbox behind posthog-code-inbox flag

[posthog]

Summary

Gates the Signals Inbox behind the posthog-code-inbox feature flag (currently rolled out to 100% in PostHog).

• Hides the InboxItem in the sidebar when the flag is off
• Skips rendering InboxView in MainLayout when the flag is off, even if the view is navigated to
• Skips the sidebar's signal-count polling (useInboxReports) when the flag is off to avoid unnecessary network requests

Flag: posthog-code-inbox — boolean, 100% rollout.

Test plan

• With the flag enabled, the inbox sidebar item renders and the inbox view is reachable
• With the flag disabled, the inbox sidebar item is hidden and the inbox view does not render
• With the flag disabled, network tab shows no getSignalReports polling from the sidebar badge

Comment:
**`CYCLE_START_DELAY_MS` uses all-features count regardless of flag**

`CYCLE_START_DELAY_MS` is a module-level constant computed from `ALL_FEATURES.length` (5), so when inbox is disabled and only 4 features render, the stagger delay before cycling begins is 100 ms longer than necessary. The constant could be moved inside the component (or derived from `features`) to stay in sync with the actual list length.

How can I resolve this? If you propose a fix, please make it concise.

@copilot resolve the merge conflicts in this pull request

Resolved and pushed in commit 3eca7dcf.

I merged origin/main into this branch and resolved the conflicts in:

• apps/code/src/renderer/components/MainLayout.tsx
• apps/code/src/renderer/features/settings/components/SettingsDialog.tsx

No user-facing UI changes were introduced by this conflict resolution, so there’s no meaningful UI screenshot to share.

[Twixes]

A couple of things, coming from our Slack thread:

• Inbox should be default rolled-out, with it being gated if the flag is on; it's a core part of PH Code
• the gated state should be a waitlist, something along the lines of "We're just scaling up this feature to provide you with a great experience; sign up and we'll let you know when self-driving is available to you"
