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: `script/` Scripts-to-Rule-Them-All
entrypoints with the `Makefile` as thin shims; a `Dockerfile` whose
`lint` and `test` phases gate the build; `.gitea/workflows/` CI running
`script/cibuild`; `REPO_POLICIES.md`, `.editorconfig`, `.dockerignore`,
`LICENSE` (WTFPL), `TODO.md`, `.gitignore`. The `.golangci.yml` is
byte-identical to the canonical copy in the `prompts` repo
(`https://git.eeqj.de/sneak/prompts/raw/branch/main/.golangci.yml`).

The 211 lint findings were fixed, not suppressed: package globals became
functions/fields/a command constructor, magic numbers became named
constants, `ctx` threads into the probes, loop functions were split to
cut complexity. Behavior is unchanged; the log file mode stays `0644`.
Four `//nolint:gosec` remain — G204 on the fixed-argv subprocess calls,
G304 on the operator-chosen log file — matching the reference repos.

`make check` is green (lint and tests run in Docker).

 rtnetmon is a WTFPL-licensed Go terminal (CLI/TUI) network monitor by
 [@sneak](https://sneak.berlin) that shows real-time network health, packet
-loss, and latency across one or two network interfaces on Linux and macOS.
+loss, and latency across two Linux network interfaces at once.
 
 ## Overview
 
 rtnetmon is a terminal-based network monitoring tool that provides real-time
-visibility into network health, packet loss, and latency across one or two
-network interfaces simultaneously. It runs on Linux and macOS and uses a
-terminal dashboard interface.
+visibility into network health, packet loss, and latency across two network
+interfaces simultaneously. It's designed for Linux systems and uses ncurses
+for a clean, real-time dashboard interface.
 
 ## Features
 
-- **Interface Monitoring**: Monitor one or two network interfaces simultaneously
+- **Dual Interface Monitoring**: Monitor two network interfaces simultaneously
 - **Real-time Updates**: Live dashboard with sub-second updates
 - **Comprehensive Metrics**:
-    - ICMP reachability tests
-    - Packet loss percentage
-    - TCP connection latency
-    - Interface health status
-- **Visual Indicators**: Color-coded status, spinners, and meters for quick
-  status assessment
-    - Packet loss meter uses reverse coloring (empty/green = good, full/red =
-      bad)
+  - ICMP reachability tests
+  - Packet loss percentage
+  - TCP connection latency
+  - Interface health status
+- **Visual Indicators**: Color-coded status, spinners, and meters for quick status assessment
+  - 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.
