test: stop integration runs failing on teardown console race

[macko911]

Problem

Integration CI can fail even when every test passes. Under Vitest 4, worker console output is intercepted and shipped to the main process over an RPC. Handlers in these tests do fire-and-forget logging that outlives the request (e.g. the proxy's enrichOperation in a finally block), so a stray log can fire as the worker tears down and race the closing RPC. The run then fails with EnvironmentTeardownError: Closing rpc while "onUserConsoleLog" was pending, attributed to allProxy.integration.test.ts — the most recent occurrence passed all 317 tests but still exited 1.

Solution

• Set disableConsoleIntercept: true in vite.integration.config.ts so worker console writes go straight to stdout/stderr, removing the RPC the stray log was racing.

This is a class of flake — any integration test whose handler logs asynchronously can trip it, not just the proxy suite. No test relies on Vitest's console interception.

Trade-offs

Pros

• Removes the whole onUserConsoleLog teardown-race flake class, not just the proxy case.
• No production or test-logic change; a genuine failure still prints its test name and assertion stack (that comes from the test result, not console interception).
• Safer than the alternatives: dangerouslyIgnoreUnhandledErrors would swallow real unhandled errors, and fixing it at the source would mean blocking HTTP responses on fire-and-forget logging.

Cons

• Log lines lose their stdout | file > test prefix, so free-floating logs are no longer attributable to a specific test in CI output.
• Console output can interleave more messily (low impact here — this config runs maxWorkers: 1 + fileParallelism: false, so logs stay serial).
• Applies to all integration tests — the option is project-level, can't be scoped to one file.

Testing

• Ran allProxy.integration.test.ts against the fix: 7/7 pass, no Errors line and no EnvironmentTeardownError.
