SKIP: 'test-patches.R:246:3' ----------------------
Reason: nzchar(Sys.getenv("BINCRAFT_PATCH_E2E")) is not TRUE

[ FAIL 0 | WARN 0 | SKIP 1 | PASS 38 ]
```

## Changes Made

### 1. test-patches.R
Added guarded e2e test at line 246. The test:
- Skips unless BINCRAFT_PATCH_E2E env var is set (via `skip_if_not(nzchar(Sys.getenv("BINCRAFT_PATCH_E2E")))`)
- Skips if offline (via `skip_if_offline()`)
- Creates a patches registry with RcppParallel env override
- Calls `build_binary_package()` on rts2 with patches
- Expects result to be TRUE or "skipped"

### 2. DESCRIPTION
Bumped `Version:` from `4.2.2.9999` to `4.3.0.9999`

### 3. NEWS.md
Prepended new section:
```markdown
# bincraft 4.3.0

* `build_binary_package()` gains a `patches` argument: a registry of
  per-package env / configure / Makevars overrides and source diffs that are
  pre-built into patched binaries and served to pak, fixing compiler- and
  OS-specific failures (e.g. RcppParallel) including for transitive deps.
```

[feat/package-patching d1efec8] test(patches): guarded end-to-end test; bump to 4.3.0.9999

## Test Result Summary
- All 38 prior tests PASS
- New e2e test SKIPPED (expected — BINCRAFT_PATCH_E2E not set)
- No failures or warnings
- Test will run (not skip) when container executes with `BINCRAFT_PATCH_E2E=1` set

## Environment Note
The guarded e2e test correctly skips in the local environment (BINCRAFT_PATCH_E2E not set). The actual test execution is deferred to the Linux build-env Docker container run with `BINCRAFT_PATCH_E2E=1` environment variable, where it will build rts2 with the RcppParallel patch applied.
