test(ws,browser): add test suites for ws and browser packages

- Add ws/server_test.go: WebSocket connection, namespace filtering, non-upgrade rejection, SetUpgrader - Add ws/namespaces_test.go: NamespacesHandler response format and content - Add browser/browser_test.go: template rendering, ws URL construction, trailing slash handling - Fix goimports whitespace in ws/server.go
feat(log): add Logger.Debugln, expand test coverage, update Go/CI (#21 )

 ### 6. Stderr Client Uses All Namespaces
 The built-in stderr client (created in `init()`) listens to all namespaces:
 ```go
-stderrClient = CreateClient(DefaultNamespace)
+stderrClient = CreateClient() // No args = all namespaces
 ```

-But only prints logs matching its own namespace in `logStdErr()`:
+It prints logs matching its level and namespace filter in `logStdErr()`:
 ```go
 if e.level >= c.LogLevel && c.matchesNamespace(e.Namespace) {
    fmt.Fprintf(os.Stderr, "%s\t%s\t[%s]\t%s\t%s\n", ...)
 }
 ```

-**Wait, that's a bug!** The stderr client is created with `DefaultNamespace` but should be created with no namespaces to see all logs. Let me check this.
-
-Actually looking at the code:
-```go
-stderrClient = CreateClient(DefaultNamespace)

-This means stderr client only sees "default" namespace logs. This might be intentional, but seems like a bug. Should probably be:
-```go
-stderrClient = CreateClient() // No args = all namespaces

+Since `CreateClient()` is called with no arguments, the Namespaces slice is empty, which means it matches all namespaces.

 GitHub Actions workflow (`.github/workflows/ci.yaml`):
- Still uses Go 1.21 (should update to 1.24.4 to match go.mod)
- No changes needed for v2 functionality

Tai Groot	5cb1329155	feat(slog): add slog.Handler adapter (#20 ) * docs: add example programs for common usage patterns Adds four focused examples in examples/ directory: - basic: drop-in logger with web UI - namespaces: namespace-based logging by component - client: programmatic log client with filtering - log-levels: all log levels and filtering Fixes #7 * feat(slog): add slog.Handler adapter for log-socket Implements log/slog.Handler that routes structured log records into the log-socket broadcasting system. Supports namespaces, WithAttrs, WithGroup, and configurable minimum level. Also adds Broadcast() as a public entry point for adapter packages that construct log.Entry values directly. * chore: update to Go 1.26, resolve slog LogValuer values	2026-03-01 22:48:12 -05:00
