Adds a dynamic `--log-level` flag (debug, info, warn, error; case-insensitive) to the server binaries, backed by a `slog.LevelVar` in `serverboot`. Defaults to `info` — no behavior change unless the flag is set. - **serverboot**: the LevelVar behind `InitLogger`'s handler; `SetLogLevel(string)` to parse and set it (empty string = unset, a documented no-op); `LogLevel()` returns a `slog.Leveler` for binaries that build their own handler. - **atelet, ateapi**: new pflag, fatal on an invalid value. - **ateom-gvisor, ateom-microvm**: flag accepted by the binary; note their container args are built by the WorkerPool controller with no pass-through yet, so wiring it is a follow-up — and that follow-up must roll out only after this change's ateom images are deployed (older images reject unknown flags and would crashloop). - **atenet (router + dns)**: replaces two pre-existing hand-rolled `--log-level` parsers that silently fell back to `info` on a bad value; both now use `serverboot.SetLogLevel` and `serverboot.InitLogger`, which also adds `ate.dev/trace-id` correlation to atenet logs. - **Kind manifests**: atelet runs at `--log-level=debug` on kind (dev/CI), so e2e suites can assert on per-item log lines; production installs keep `info`. Motivation: groundwork for #463 Phase 2 observability — per-item GC log lines can ship at Debug and be enabled per-node instead of landing at Info. **Testing**: unit tests pin the untouched default at exactly `info`, dynamic raise/lower, case-insensitivity, invalid-value rejection, and the empty-string no-op; `go test -race` green across serverboot, atenet, atelet, ateapi.
