feat: 本地 HTTP 看板、探活与 Prometheus 指标（ponte serve） - #23
Conversation
`ponte watch` 只服务坐在机器前的人。新增的 `ponte serve` 把同一份状态摆到 HTTP 上：/ 是自包含看板，/healthz 供监控探活，/metrics 是 Prometheus 文本 格式，/status.json 与 `ponte status --json` 完全一致。 - /healthz 报的是隧道而不是进程：守护进程没跑或任一条隧道异常都回 503， 但首次健康检查完成前回 200 + "starting"——否则每次重启都会误报。 - /metrics 故意永远回 200（采挂掉会盖住“为何挂了”），值与 CLI 渲染同源， 端口监听状态是其中最值得报警的一条。 - 看板会列出服务器、用户与转发端口，因此默认只绑回环；绑定非回环地址必须 带 token，配置加载与 CLI 走同一条校验，直接拒绝而不是警告。 - 纯标准库 http.server，不引入新依赖；全部只读、逐请求重读状态且 no-store。 - 顺带把 SSH 目标（destination）纳入 ProfileStatus 与 status --json。

Remove query-token authentication from the public contract.
PonteRequestHandler._authorized accepts ?token=. log_message logs the complete request line, so the application log can retain this credential. The README also documents query tokens for browsers, scrapers, and Prometheus, including English and Chinese metrics_path examples. Cache-Control: no-store does not protect request URLs.
Accept Authorization: Bearer only. Remove the query-token fallback and update README.md, CHANGELOG.md, and ponte/config.example.toml. Prometheus clients can use header-based authorization instead.

Do not classify hostname prefixes as loopback addresses.
127.example.test passes is_loopback_host() although it is a hostname, not an IPv4 literal. If it resolves to a non-loopback IPv4 address, PonteHTTPServer binds to that address after the token check is bypassed, exposing the unauthenticated HTTP status surface.
Use ipaddress.ip_address(...).is_loopback for IP literals and treat hostnames as exposed unless explicitly resolved and verified as loopback addresses. Add a regression test for a hostname beginning with 127..

Require an HTTPS boundary for non-loopback ponte serve binds.
ponte serve deliberately permits non-loopback HTTP when token is set. This exposes bearer or query tokens and infrastructure status to network observers, who can replay the token. Do not rely on token authentication alone for non-loopback access. Require TLS, or restrict the server to loopback and terminate TLS in a reverse proxy.

Redact query strings before logging HTTP requests.
The standard library passes the full request line to log_message. When query-token authentication is used and DEBUG logging is enabled, logger.debug can persist the bearer token. Strip the query before logging the request line.

Close the connection after rejecting body-bearing methods.
PonteRequestHandler uses HTTP/1.1, and do_POST, do_PUT, and do_PATCH call _method_not_allowed without consuming the request body. BaseHTTPRequestHandler keeps the connection open for HTTP/1.1 requests. _send_json sends Content-Length, but neither it nor send_response adds Connection: close. Unread body bytes can therefore be parsed as the next request line on a reused connection.
Close the connection instead of draining an unknown request body. This safely handles both Content-Length and chunked requests without an unbounded read:

ponte watch只服务坐在机器前的人。这个 PR 加ponte serve，把同一份状态摆到 HTTP 上，给浏览器、手机（同机）、Uptime Kuma、Prometheus 用。//healthz200，任一条断开立即503/metrics/status.jsonponte status --json完全一致的载荷三个关键取舍
/healthz报的是隧道，不是进程。 守护进程没跑或任一条隧道异常 →503（并在 body 里点名unhealthy/errors）。但首次健康检查完成前回200+"starting"：默认check_interval = 60s，把这段窗口算成“挂了”会让每次重启都误报一次。/metrics故意永远回200。 与/healthz分工不同：前者供报警，后者供画图——采集失败会盖住“为何挂了”，而那正是图要回答的问题。缺失的值选择省略而不是导出NaN（空缺表示“无数据”，NaN 只会引人猜）。全部值与 CLI 渲染同源（同一个 payload），所以网页不可能和ponte status说不一样的话。最值得拿来做告警规则的是ponte_profile_port_listening == 0：进程活着、端口没了，正是那种悄无声息的典型故障。默认只绑回环，对外必须给令牌。 看板会列出服务器地址、登录用户与转发端口——这是一张内网拓扑图。所以绑定非回环地址而没配
token时，配置加载与ponte serve都直接拒绝（不是警告），客户端再用?token=或Authorization: Bearer带上。""（http.server 语义为“所有网卡”）一律按对外处理，白名单判定，未知写法不予放行。实现要点
http.server，不引入新依赖；只读、逐请求重读状态、Cache-Control: no-store，页面不可能拿旧数据骗人。ProfileStatus新增destination（取自配置），进入status --json契约与status表格首行：多隧道时，“这张表是哪个服务器”是第一件要说清的事。ponte config只报令牌“有没有”，绝不回显（那输出经常被粘进 issue）。验证
