isPortAvailable() previously bound a one-shot Bun.serve and stopped it.
That call was reachable from the plugin bundle through
src/shared/index.ts barrel re-export and crashed on Electron.
Switch to node:net.createServer().listen(port, host), which Bun fully
implements as well. Adds a 2s safety timeout and removes both
"error" and "listening" handlers on resolution to prevent listener
leaks. Behavior is bit-equivalent: returns true iff a server can bind
to (host, port) right now.
Test file is fully rewritten away from stale Bun.serve mocking. New
tests exercise: free-port detection via port 0, EADDRINUSE handling
via a real net.createServer blocker, findAvailablePort range
exhaustion, getAvailableServerPort auto-selection, 127.0.0.1 default
hostname binding, and probe-server resource cleanup.
- connected-providers-cache: extract factory pattern (createConnectedProvidersCacheStore) for testable cache dir injection
- port-utils.test: environment-independent tests with real socket probing and contiguous port detection
- resolve-file-uri.test: mock homedir instead of touching real home directory
- github-triage: update SKILL.md
