[CHORE] Rename all UnravelDocs/unraveldocs identifiers in docker-compose.yml

[aniebietafia]

Problem

docker-compose.yml is saturated with the old brand identity across service names, container names, network definitions, and environment variable defaults:

Element	Current Value
Service name	unraveldocs-api
Container name	unraveldocs-api
POSTGRES_DB default	unraveldocs
Postgres healthcheck DB	unraveldocs
Elasticsearch cluster.name	unraveldocs-cluster
Elasticsearch node.name	unraveldocs-node
Docker network	unraveldocs-net

This means docker-compose up starts a container named unraveldocs-api, connects to a database named unraveldocs, and registers an Elasticsearch cluster named unraveldocs-cluster. All three contradict the new brand.

Proposed Solution

Replace all occurrences with xtraction equivalents throughout docker-compose.yml.

User Stories

• As a developer running the local stack, I want Docker container names, network names, and service identifiers to reflect xtraction so I can easily identify running services.
• As a DevOps engineer, I want Elasticsearch cluster and node names to use the new brand for correct identification in monitoring tools like Kibana and Datadog.

Acceptance Criteria

• Service name is xtraction-api
• Container name is xtraction-api
• POSTGRES_DB default is xtraction
• Postgres healthcheck references xtraction DB
• Elasticsearch cluster.name=xtraction-cluster
• Elasticsearch node.name=xtraction-node
• Docker network is xtraction-net
• grep -i "unraveldocs" docker-compose.yml returns zero results
• docker-compose up -d starts all services cleanly

Proposed Technical Details

# Before
services:
  unraveldocs-api:
    container_name: unraveldocs-api
    ...
networks:
  unraveldocs-net:

# After
services:
  xtraction-api:
    container_name: xtraction-api
    ...
networks:
  xtraction-net:

Each service's networks reference must also be updated from unraveldocs-net to xtraction-net.

Tasks

• Rename service unraveldocs-api → xtraction-api
• Update container_name → xtraction-api
• Update POSTGRES_DB default → xtraction
• Update Postgres healthcheck DB name
• Update Elasticsearch cluster.name and node.name
• Rename network unraveldocs-net → xtraction-net
• Update all networks: references in every service block
• Run docker-compose up -d and verify all containers start
• Run docker ps and confirm container names

Open Questions / Considerations

• Existing Docker volumes (e.g., postgres_data) may contain data from the unraveldocs database. Developers running persistent volumes need to either drop and recreate them or run a database rename. Add a migration note to the PR description.
