fix(changelog): Fix 404 on /changelog/ page and add navigation

[sfanahata]

• Add /changelog/ page showing recent documentation updates
• Add GitHub Action to generate changelog from merged PRs daily
• Add "Docs Changelog" to Manage dropdown and mobile nav
• Rename existing changelog links to "Product Changelog" for clarity
• Generate markdown with links to actual doc pages (not filenames)
• Skip large PRs (100+ files) to avoid incomplete data

Autofix Details

Bugbot Autofix prepared a fix for the issue found in the latest run.

• ✅ Fixed: File filter condition is too permissive using OR
  • Changed filter logic from OR to AND, requiring files to both start with docs/ and match .mdx extension, consistent with getPageTitle and fileToUrl functions.

@sfanahata lots of unrelated changes to backlog (formatting, etc) - do you know why these are ending up here?

[sergical]

something is telling me a daily cron that checks all PRs and scans files and parses all of that isn't the right solution here. I might be wrong, but have we considered just doing a standard Changelog.md that can be fetched on the changelog page and rendered nicely as markdown (or even consumed directly using mdx).

Wondering what decision caused us to pursue this route. I am not 100% against it but I am not 100% aligned either 😅

Good catch. This was implemented so I could test the formatting locally. I didn't realize it was bloating the PR. I removed it.

Oh, and a rebase pulled all the commits in. 🤦

I was exploring still having the changelog accessible to other services (via API), but I don't think we need that anymore. I've had the solution rewritten to your recommendation. Seems to still look good. Will ping you when it's ready for re-review.

@sfanahata looks good! Is there a way to make it a little more human-readable? The previous version was providing brief LLM-generated summaries describing the changes in the PR, I felt like that was valuable.
