- server: reject Start() when config is nil to prevent panic
- app_common: guard empty Servers slice in initHTTP2/3 and logServerAddresses
- proxy/health: handle nil HealthCheckConfig with defaults
- resolver: handle nil ResolverConfig by returning noopResolver
- middleware/headers: skip UpdateConfig when cfg is nil
- middleware/sliding_window: enforce minimum window duration of 1s
- lua/api_log: map EMERG/ALERT/CRIT to Error() instead of Fatal()
to prevent Lua scripts from killing the entire server process
- Add comments for lua/api_log.go HTTP status codes and log levels
- Add comments for variable/builtin.go and ssl.go constants
- Add comments for utils/httperror.go error variables
- Add comments for matcher/matcher.go location types
- Add comments for compression/compression.go algorithms

Conflict: sendfile.go (!linux build tag) was incorrectly modified to
include linuxSendfile and getSocketFd functions which already exist
in sendfile_linux.go.
Resolution: Keep HEAD version (simple fallback returning ENOTSUP) as
Linux implementation is properly separated in sendfile_linux.go.

为定时器回调上下文注册不安全的 ngx API 时返回错误：
- ngx.ctx: 请求上下文不可用
- ngx.req: 请求 API 不可用
- ngx.resp: 响应 API 不可用
- ngx.var: 变量 API 不可用
- ngx.log: 提供安全版本（不依赖 RequestCtx）
防止定时器回调中误用请求相关 API 导致并发问题。
