Timers 1.7.0: the LTC capture tool ships prebuilt, for Apple silicon and Intel

The tool used to be compiled by the macOS app build, or by the module
itself on the booth with swiftc — and a catalog install got source only,
which the unbundled 1.10.0 shell made every fresh install. Under the module
guide's rule it now ships built: bin/ltc-capture-macos-arm64 and
bin/ltc-capture-macos-x86_64, signed with the Developer ID (hardened
runtime, audio-input entitlement), from native/ltc-capture.swift via
native/build.sh. Nothing is built or looked for on the machine any more:
captureTool() picks the binary for this platform, and where there is none
— Windows, until a Windows implementation exists — timecode reports itself
off in the tile and the health line while the rest of the module runs.
The runtime build, its "building…" states and the device picker's build
kick are gone with it. The old top-level binary is no longer gitignored
(it is no longer written).

+
+### Native helpers
+
+Some features need a program JavaScript cannot be: reading an audio input,
+decoding timecode, measuring sound. Rule 3 says the module owns that program;
+this section says how it ships: **already built, for every platform it runs
+on, inside the module folder.** The machine running ProdDash is a packaged
+app or the Windows bundle plus modules from the admin page's catalog. It has
+no compiler and never will — the catalog delivers exactly the folder that is
+in the repo, so the binaries live in git next to the code.
+
+- **Platforms.** Apple silicon macOS and 64-bit Windows are required. Intel
+  macOS is welcome but optional. One file per platform in `bin/`, named for
+  what it is:
+
+  | Platform | File |
+  | --- | --- |
+  | macOS, Apple silicon | `bin/<name>-macos-arm64` |
+  | Windows, 64-bit | `bin/<name>-win-x64.exe` |
+  | macOS, Intel (optional) | `bin/<name>-macos-x86_64` |
+
+- **Pick it at runtime, and cope without it.** Choose by `process.platform`
+  and `process.arch`; when there is no file for this machine, the feature
+  says so — in `health()` and in the tile's `setStatus` — and everything else
+  in the module keeps working. Never try to build it, never look for a copy
+  elsewhere on the machine, never tell the operator to install anything.
+
+  ```js
+  const HELPERS = {
+    darwin: { arm64: 'ltc-capture-macos-arm64', x64: 'ltc-capture-macos-x86_64' },
+    win32: { x64: 'ltc-capture-win-x64.exe' },
+  };
+  const name = HELPERS[process.platform]?.[process.arch];
+  const helper = name ? path.join(__dirname, 'bin', name) : '';
+  if (!helper || !fs.existsSync(helper)) {
+    // Timecode is off on this platform. Say it once, keep the clock running.
+  }
+  ```
+
+- **One contract, any language.** Every platform's binary speaks the same
+  command line and output format, so `server.js` has one code path. What is
+  behind it is your choice per platform — Swift against CoreAudio on macOS,
+  C#, C or Rust on Windows — the module does not care.
+- **Source and build beside it.** Keep the source under `native/` with one
+  script that produces every `bin/` file from a checkout, so any binary can be
+  rebuilt from what is committed. A helper that cannot be rebuilt does not
+  ship.
+- **Bump the module version whenever a binary changes**, like any other
+  file — that is how installs learn about it.
+- **Keep them lean.** Optimised builds, no debug symbols, a few megabytes at
+  most: the catalog fetches the whole repo as one archive, capped at 80 MB.
+- **Signing.** Apple silicon refuses unsigned code, so sign the macOS binary
+  — Developer ID when you have it, ad-hoc at least. Windows needs nothing:
+  files the app writes carry no download mark, so SmartScreen never sees
+  them. Permissions come from the launcher (see "Permissions macOS has to
+  grant"), not from the binary.
+
+A helper that ends up existing for one platform only is an exception made
+on purpose, not a default: say so in the module's README and in the health
+line, so a Windows booth knows why the feature is off.
