* fix: resolve deadlock in config handler during plugin initialization
The config handler and createBuiltinAgents were calling fetchAvailableModels
with client, which triggers client.provider.list() API call to OpenCode server.
This caused a deadlock because:
- Plugin initialization waits for server response
- Server waits for plugin init to complete before handling requests
Now using cache-only mode by passing undefined instead of client.
If cache is unavailable, the fallback chain will use the first model.
Fixes#1301
* test: add regression tests for deadlock prevention in fetchAvailableModels
Add tests to ensure fetchAvailableModels is called with undefined client
during plugin initialization. This prevents regression on issue #1301.
- config-handler.test.ts: verify config handler does not pass client
- utils.test.ts: verify createBuiltinAgents does not pass client
* test: restore spies in utils.test.ts to prevent test pollution
Add mockRestore() calls for all spies created in test cases to ensure proper cleanup between tests and prevent state leakage.
* test: restore fetchAvailableModels spy
