fix(client): ignore forward console send failures (fix #22407)

[cyphercodes]

Description

Fixes #22407.

When forward console reports logs or unhandled errors after the client transport disconnects, transport.send() rejects. If that rejection is left unhandled, the forward console unhandledrejection listener can try to forward the send failure too and enter a loop.

This change routes forwarded console payloads through a shared helper that catches send failures and drops them when the transport is no longer available.

Tests

• pnpm --filter vite build-bundle
• pnpm run test-unit packages/vite/src/shared/__tests__/forwardConsole.spec.ts
• pnpm exec eslint packages/vite/src/shared/forwardConsole.ts packages/vite/src/shared/__tests__/forwardConsole.spec.ts --concurrency auto
• pnpm --filter vite build-types
• pnpm --filter vite typecheck
• git diff --check

Thanks, but I created a separate PR (#22450) as I thought we should log the unexpected errors and also the tests added here can be flaky.
