silverwind a4a6e291d5 fix: protect all r.closed accesses, add race test, enable -race in CI ...

The initial `if r.closed` guard in RunDaemon() was still reading
r.closed without holding closedM, causing a data race with Close().
Wrap it with closedM to match the other access sites.

Add TestReporter_RunDaemonClose_Race which exercises RunDaemon() and
Close() concurrently — the exact scenario from #793. Without the fix,
`go test -race` reliably detects the data race.

Enable the -race flag in `make test` so CI catches data races.
