Changes

MongoDB URI construction

Layer / File(s)	Summary
URI construction and module exposure src/domain/mod.rs, src/domain/mongodb/mod.rs, src/domain/mongodb/connection.rs	MongoDB modules are public. URI construction handles multi-host authorities and option-driven authentication, replica set, and TLS parameters.
URI generation tests src/tests/domain/mongodb.rs, src/domain/mongodb/connection.rs	Tests cover URI schemes, authentication defaults, dry-run paths, query options, replica sets, and credential encoding. Previous inline URI tests were removed.

Database environment configuration

Layer / File(s)	Summary
MongoDB service configuration docker-compose.databases.yml	Both MongoDB services use mongo:8.0.4. The authentication healthcheck uses mongosh with the existing ping settings.

Repository ignore rules

Layer / File(s)	Summary
Docs directory ignore rule .gitignore	The /docs directory is added to the ignore rules.

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 6f8a5

Multi-host MongoDB deployments using a shared non-default port can connect to the wrong endpoints, while existing development volumes created by a newer MongoDB image may prevent database startup. Resolve both compatibility issues before merging.

In `@docker-compose.databases.yml`:
- Around line 65-85: Update the MongoDB service image versions and startup
configuration to remain compatible with the existing mongodb-data-auth and
mongodb-data volumes, or add explicit backup, migration, and volume-recreation
handling before startup. Preserve both named volume mounts and ensure the docker
compose down workflow does not attempt an unsupported MongoDB downgrade.

In `@src/domain/mongodb/connection.rs`:
- Line 45: Update the authority construction around is_srv and is_multi_host so
bare multi-host entries retain cfg.port when it is nonzero, applying the shared
port to each host while leaving explicitly ported and bracketed IPv6 entries
unchanged. Add a regression test covering bare hosts such as db1,db2 with a
non-default port.
