feat: 把 A 端的 Session/KCP/视频/控制 都收口到一个本地 daemon 进程里，Django 和输入发送端都改成通过本机 UDS HTTP 去访问它，同时补齐了观测、性能和可用性上的几个关键问题。

+## A-Side OmniDaemon
+
+The A-side daemon is configured from `config/a_side_omnidaemon.yaml` in this repo. The safest way to start it is to pass that file explicitly, because the installed Python package does not bundle the YAML config.
+
+Run from a source checkout:
+
+```bash
+python -m omnisocket_a_side.daemon --config "$(pwd)/config/a_side_omnidaemon.yaml"
+```
+
+Or, if you installed the console script:
+
+```bash
+OMNIDAEMON_CONFIG="$(pwd)/config/a_side_omnidaemon.yaml" \
+omnisocket-a-side-daemon
+```
+
+Optional overrides:
+
+- `OMNIDAEMON_SOCKET=/tmp/omnisocket-a-side.sock` selects the local UDS path.
+- `OMNIDAEMON_CONFIG=/abs/path/to/a_side_omnidaemon.yaml` overrides `--config`.
+
+For `robot-command-center` and the A-side senders, keep the daemon and its clients on the same Linux machine so they can share the Unix-domain socket.
