Adopt repo standards: scaffold, policies, lint-clean (closes #1 )

Add the standard scaffold and bring the tree to a clean lint under the vendored `default: all` config. New: `script/` Scripts-to-Rule-Them-All entrypoints with the `Makefile` reduced to thin shims; a `Dockerfile` whose `lint` and `test` phases gate the build (final stage depends on both); a `.gitea/workflows/` CI running `script/cibuild`; the vendored `.golangci.yml`; `REPO_POLICIES.md`; `.editorconfig`; `.dockerignore`; a `LICENSE` (WTFPL) and `TODO.md`; and a comprehensive `.gitignore`. The 211 lint findings were fixed, not suppressed: package-level state became functions/fields/a command constructor, magic numbers became named constants, `ctx` is threaded into the probes, the loop functions were split to cut complexity, and the deprecated `+build` tags were dropped. Behavior is unchanged. The only annotations are justified `//nolint:gosec` on the `ping`/`curl` subprocess calls (G204, fixed argv) and the operator-chosen log file (G304), matching the reference repos. `make check` is green (lint and tests run in Docker). Model: opus-4-8

 rtnetmon is a WTFPL-licensed Go terminal (CLI/TUI) network monitor by

 rtnetmon is a terminal-based network monitoring tool that provides real-time

    - Packet loss meter uses reverse coloring (empty/green = good, full/red =
      bad)
 - **Detailed Logging**: Optional logging to file for debugging and analysis
 ## Requirements
- Linux or macOS
+- Linux operating system
 - Go 1.21 or later
 - Root/sudo access (for raw ICMP packets)
 - `ping` command available in PATH
 - On Linux: `ip` (with `/proc/net/route` as a fallback)
 - On macOS: `netstat`
 ## Platform support and interface detection
 rtnetmon monitors either one or two interfaces, chosen automatically for the
 platform it runs on. When only one interface is detected, the dashboard shows a
 single pane.
 **Linux.** The two named interfaces (`--ifaceA`/`--ifaceB`, default
 `gu0`/`backhaul0`) are used when both exist — this is the original dual-bridge
 setup, unchanged. When neither exists, the single default-route interface is
 monitored instead.
 **macOS.** The physical internet interface is found from the default route. When
 a VPN client is running (Mullvad and similar clients create a `utun` tunnel that
 carries a default route or holds a routable address), that tunnel is monitored
 as the primary pane alongside the physical interface. With no VPN running, only
 the physical interface is monitored. Interface names are detected on macOS; the
 `--ifaceA`/`--ifaceB` flags are not used there, but `--labelA`/`--labelB` still
 set the pane labels.
 ### Supported matrix
 | OS    | Interfaces monitored                                        |
 | ----- | ----------------------------------------------------------- |
 | Linux | `gu0` + `backhaul0` when both exist (two panes)             |
 | Linux | the single default-route interface otherwise (one pane)     |
 | macOS | VPN tunnel + physical default-route interface (two panes)   |
 | macOS | the physical default-route interface with no VPN (one pane) |
 Anything outside this matrix — on Linux, only one of the named pair present, or
 no/multiple default routes when neither is present; on macOS, no default route
 or more than one physical default route — exits with a clear error.
 ## Starlink status
 When the non-VPN physical gateway is a Starlink dish, two extra lines appear
 under that pane: dish state, uptime, obstruction and alert count on the first,
 and pop-ping latency and drop rate with downlink/uplink throughput on the
 second. They turn red when the dish is not connected or an alert is active.
 Detection is a TCP connect to the dish's fixed local endpoint,
 `192.168.100.1:9200`, made over the physical interface (the same binding the
 latency probes use). The dish sits behind the Starlink router, so this is not a
 gateway-address check. rtnetmon probes once a minute until a dish answers and
 then reads its status every few seconds; when no dish answers, nothing is drawn
 and no status is fetched. The status comes from the dish's local `get_status`
 gRPC call.
