feat(cli): CLI 插件能力对齐 WebUI（memory/knowledge/config/tracker/adapters/network）

原来 CLI 插件只覆盖 WebUI 的一小部分：/memory 只有 query、/knowledge 只有
list、没有 config/tracker/adapters/network，结构化输出还各拼一套文本格式。

按 WebUI 的 REST 面对齐：
- /memory query|graph|text [n]     （对应 /memory、/memory/graph、/memory/text）
- /knowledge | delete <name> | stats（对应 GET/DELETE /knowledge）
- /config                          （对应 GET /config）
- /tracker | rollback              （对应 GET /tracker、POST /tracker/rollback）
- /adapters | remove <name>        （对应 GET/DELETE /adapters）
- /network                         （对应 GET /network）
- 统一 writeJSONContent：结构化数据一律缩进 JSON，与 WebUI 同口径。

waiter 侧同步：把上述命令在 local（发 CLI 插件）与 remote（走 REST）两条路
都接上，/help 补齐；两条路语义一致。
