test: connections — env-var loading and MongoDB auth detection

[anandgupta42]

What does this PR do?

1. loadFromEnv — src/altimate/native/connections/registry.ts (5 new tests)

The ALTIMATE_CODE_CONN_* env-var connection loading path had zero unit test coverage. CI/CD users rely on this to inject warehouse connections without config files on disk. If JSON parsing or name normalization (uppercase prefix → lowercase key) broke, connections would silently fail to load with no indication why.

New coverage includes:

• Valid env var parsing with name lowercasing
• Malformed JSON is silently ignored (no crash)
• Config objects missing the type field are rejected
• Empty env var values are ignored
• Multiple env var connections are parsed correctly

2. detectAuthMethod for MongoDB — src/altimate/native/connections/registry.ts (3 new tests)

PR #482 added MongoDB driver support with a new branch in detectAuthMethod (line 229) that returns "connection_string" for MongoDB connections without a password. This branch had zero test coverage. Wrong auth detection means incorrect telemetry for MongoDB users.

New coverage includes:

• type: "mongodb" without password → "connection_string"
• type: "mongo" (alias) without password → "connection_string"
• type: "mongodb" with password → "password" (exercises the generic password check path)

Type of change

• New feature (non-breaking change which adds functionality)

📝 Walkthrough

Walkthrough

Added two test files to expand test coverage: one for ConnectionRegistry.loadFromEnv behavior testing environment variable parsing scenarios (valid JSON, malformed JSON, missing fields, empty values, and multiple variables), and another for Registry.detectAuthMethod testing MongoDB authentication detection paths directly.

Changes

Cohort / File(s)	Summary
Registry Environment Loading Tests packages/opencode/test/altimate/registry-env.test.ts	New test suite covering Registry.load() via ConnectionRegistry.loadFromEnv, verifying JSON parsing from ALTIMATE_CODE_CONN_* env vars, connection name lowercasing, malformed JSON handling, missing type field handling, empty values, and multiple variable registration.
MongoDB Authentication Tests packages/opencode/test/altimate/warehouse-telemetry.test.ts	New direct unit tests for Registry.detectAuthMethod covering MongoDB authentication detection with connection strings vs. passwords, bypassing telemetry-driven connection attempts.

Poem

🐰 A rabbit hops through test files new,
Parsing env vars, MongoDB too,
JSON and passwords, all checked with care,
Robust connections everywhere! 🌳
