refactor: long-form docker-compose syntax with de-collisioned host ports

[omranjamal]

Summary

• Converts all port mappings to long-form syntax (target/published/protocol) and volume mounts to long-form (type/source/target) for clarity and extensibility
• Shifts default host-published ports by +7 to avoid collisions with other local services using standard ports (Redis 6379, Qdrant 6333, Neo4j 7474/7687)
• Makes all host ports overridable via environment variables with sensible defaults

Port mapping

Service	Container port	Host default	Env override
Neo4j HTTP	7474	7481	NEO4J_HTTP_PORT
Neo4j Bolt	7687	7694	NEO4J_BOLT_PORT
Redis	6379	6386	REDIS_PORT
Qdrant HTTP	6333	6340	QDRANT_HTTP_PORT
Qdrant gRPC	6334	6341	QDRANT_GRPC_PORT
Neuralscape	8199	8199	NEURALSCAPE_PORT

.env.example cleanup

• Removed redundant REDIS_URL and QDRANT_URL (overridden by docker-compose environment block; Pydantic picks up the runtime env vars at higher priority anyway)
• Commented out NEO4J_PASSWORD (already defaulted via ${NEO4J_PASSWORD:-neuralscape} in docker-compose)
• Added commented-out port override vars for discoverability

Other

• Added .omc/ to .gitignore

Verification

docker compose config --quiet  # validates YAML — exits 0
# Override example:
REDIS_PORT=6379 docker compose config | grep -A2 "published"

No changes to container-internal ports, inter-container URLs, healthchecks, config.py defaults, or documentation.

Test plan

• docker compose config --quiet passes
• docker compose up -d starts all services on the new default ports
• Port overrides via .env work as expected (e.g. REDIS_PORT=6379)
• Inter-container communication unaffected (neuralscape can reach redis, neo4j, qdrant)

Review

Changes look good — long-form syntax, port de-collision, and env overrides are clean. No impact on inter-container communication, config.py defaults, or the plugin/service stack.

One note on .env.example: Removing REDIS_URL and QDRANT_URL makes sense for Docker-only usage, but for local dev (no Docker) users still need these. The README's "Local Setup" section tells users to set them. Consider keeping them as commented-out entries for discoverability:

# Local dev (non-Docker) — uncomment these:
# REDIS_URL=redis://localhost:6379
# QDRANT_URL=http://localhost:6333

Not a blocker — just a DX consideration.

Also, can you retarget this PR to dev instead of main?
