Health Checks

api.zig supports health checks for production readiness and liveness probes.

Built-in Checks

• Aggregated health status (ok/warning/fail)
• Custom checks (database, caches, external services)

Example:

var hc = try metrics.HealthChecks.init(allocator);
hc.addCheck("postgres", checkPostgresFn);
app.get("/health", (ctx) => Response.json(hc.statusJson()));

See src/metrics.zig for health check utilities and JSON output format.
