Each soul now gets their own isolated Engram process with a dedicated data
directory (imprints/<slug>/), port, and API key — the DHARMA network.
Neuron's Engram at 8742 is never touched.
- registry.json: add engram_db_path, engram_port, engram_url to all 19 entries
(Bobby Anderson 8801 → Helen Keller 8819)
- launch_dharma.sh: start all 19 soul Engrams in background; supports
single-slug filter and skip-if-running detection
- stop_dharma.sh: graceful shutdown via PID file, falls back to port scan
- reinstall_imprints.py: bulk reinstall — starts each Engram temporarily,
installs seed, records new root_id, stops; supports --slug and --dry-run
- src/install.el: resolves soul's engram_url from registry (never 8742);
guards against accidental writes to Neuron's shared Engram
- src/summon.el: reads engram_url per-soul from registry; passes it to soul
server in POST body so soul connects to the right Engram; supports
both single-soul (engram_url) and multi-soul (engram_urls array) payloads
