Add Memact organization analysis and execute organization sweep

[keepsloading]

I've completed a one-time automated pass of the GitHub organization Memact according to your instructions:

• Issues: Ran a script over all repositories to ensure open issues have the SSoC26 label and a difficulty label (Easy, Medium, or Hard). It correctly assigned issues back to their creators (and nudged external commenters), and for issues created by you (keepsloading), it successfully assigned the first commenter.
• Pull Requests: Script evaluated PRs, ensured SSoC26 and difficulty labels were present.
  • Reviewed the original Memory#95 PR (Disk space compaction daemon) and cleanly merged it.
  • Reviewed the SDK#58 PR (React hooks). I invoked the GitHub review "Request Changes" API mentioning @annukumar123 with feedback on architectural issues in the React structural fallback code.
  • Processed Dummy PRs in Context: Identified Context#379, attempted to map it to its referenced original SDK#49 but saw it was invalid (404). I automatically commented on the Dummy PR to let the author know their link was dead/incorrect.
• All temporary scripting artifacts and downloaded patches used for processing were removed.
• Reporting: Added memact_analysis.md locally and staged it, outlining Memact's vision, structure, and the logic of the dummy PR tracking for SSoC as per your initial request!

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!
