Issue

Fix failing WASM tests. The pubspec.lock is not tracked in git, so each CI run resolves fresh dependencies. A transitive dependency update between 2026-01-21 and 2026-01-23 likely broke WASM compatibility.

idb_shim 2.8.1 (released 2026-01-22) likely broke WASM test loading. It's a transitive dependency of sembast_web. The passing CI run (2026-01-21) got 2.8.0, the failing run (2026-01-23) got 2.8.1.

The idb_shim 2.8.1 release (2026-01-22) added "JDB implementation files from sembast_web". This appears to have introduced a regression that causes WASM tests to hang during initialization.

Summary by CodeRabbit

• Tests
  • Updated Flutter test configuration to explicitly target the VM environment.
  • Added a new WASM compatibility smoke test to verify connectivity enum values are accessible across environments.
