Add habit streak trackers to Habits section

[timdunn22]

Added Apps (Habits section)

• Rewire — Free private habit streak tracker with recovery phases and milestones
• FastTrack — Free intermittent fasting streak tracker with metabolic phases
• IcePlunge — Free cold plunge/cold exposure streak tracker with adaptation phases

All three are free web PWAs focused on quantified self-tracking of habit streaks, featuring phase-based progress tracking, milestone celebrations, and shareable progress cards. No account required, all data stored locally.

Thanks for these. Right now all three are hosted on anonymous vercel.app preview domains with no source repositories, which makes them hard to vet. The bigger issue is that the Rewire description says generic habit tracker, but the app itself presents as a tool for quitting porn, so the entry doesn't match the product. If you can point these to stable domains or public repos and describe each app accurately, I'm happy to reconsider.
