### Task B4: Pass `patches` through the build entry points

**Files:**
- Modify: `local/build-one.R:99-119` (the `build_binary_package` call)
- Modify: `local/build-all.R:125-145` (the `build_binary_package` call)

**Interfaces:**
- Consumes: the new bincraft `patches` argument (Phase A) and `local/patches/`.
- Produces: both entry points pass `patches = "local/patches"`.

- [ ] **Step 1: Edit `local/build-one.R`**

In the `bincraft::build_binary_package(` call, add as a new argument (e.g. after `archive = TRUE,`):

```r
    patches = "local/patches",
```

- [ ] **Step 2: Edit `local/build-all.R`**

In the `bincraft::build_binary_package(` call, add:

```r
      patches = "local/patches",
```

- [ ] **Step 3: Verify the scripts still parse**

Run: `Rscript -e 'invisible(parse("local/build-one.R")); invisible(parse("local/build-all.R")); cat("parse ok\n")'`
Expected: `parse ok`.

- [ ] **Step 4: Commit**

```bash
git add local/build-one.R local/build-all.R
git commit -m "feat(patches): pass patch registry to bincraft build calls"
```
