Add April 13 changelog: guided onboarding and automatic setup

[mintlify]

Summary

• Adds a new changelog entry for the week of April 13, covering the guided onboarding experience, automatic application/incident detection setup, and a code review sync fix.
• Creates the changelog page and adds Changelog navigation tab and anchor to docs.json (consolidating prior unmerged changelog PRs into a single file with all entries).

New changelog entry highlights

• Guided onboarding experience — step-by-step sync progress and getting-started checklist for new workspaces
• Automatic application and incident detection setup — applications created per repository and incident detection initialized during initial sync
• Code review sync fix — reviews without a submission timestamp no longer interrupt sync

Greptile Summary

This PR introduces the docs changelog page (changelog.mdx) with three entries spanning March–April 2026, and wires it into the Mintlify navigation via a new global anchor and tab in docs.json. All internal links in the changelog resolve to pages already present in docs.json, and the Mintlify <Update> component is used correctly throughout.

Confidence Score: 5/5

Safe to merge — documentation-only changes with no logic or data integrity concerns.

All findings are P2 style suggestions. The only note is a potentially blank sidebar group heading from the empty string group name, which is cosmetic and non-blocking.

No files require special attention.

Empty group name may render a blank sidebar heading

The Changelog tab uses "group": "", which could produce an empty/blank section header in the Mintlify sidebar. Every other tab uses a descriptive group name. Since there's only one page here, you can either use a meaningful label or check whether Mintlify suppresses empty group titles entirely.
