First phase of the framework constitution alpha. No behavior change for
configured installs.
- Add MIT LICENSE (root + framework bundle) + "license":"MIT" in manifests
- Drop private jarvis-brain credential fallback at 3 sites; default to
$HOME/.config/mosaic/credentials.json (aligns with #551)
- prevent-memory-write.sh: soft-degrade OpenBrain nudge via ${OPENBRAIN_URL},
removing hardcoded brain.woltje.com; still blocks the write
Refs #542, closes#569
