fix(packaging): remove the memory-service integration this CLI reintroduced

synapse/memory/service.py was deleted on 2026-08-25 when memory curation
moved in-process (curator.py) - there is no longer a second FastAPI app
to run on :8001. This CLI was evidently built against a pre-curator
baseline: `nexus serve` spawned `synapse.memory.service:app` (fails
with ModuleNotFoundError, logged only to memory.log where nobody would
see it), `nexus start memory`/`stop memory` had no handler at all
(silently fell through to show_help()), and doctor/status/monitor all
carried a "memory service" row that could never be anything but down.

Removed rather than repaired, since there's nothing to repair: the
service, its SERVICES entry, --memory-port/--no-memory, the -m/--memory
target everywhere it was offered (start/stop/logs/LEGACY_TARGETS), and
the memory_port/memory_url settings this PR had added. The `nexus
memory list|add|rm` data commands (nexus_api.py, hitting the backend's
own /memory REST endpoint) are untouched - unrelated, and still work.
