fix(build): stop per-minor objects masking the per-minor candidate list (#189)
## Motivation

`arm64/alpine324` (pipeline 11953) finished in minutes having uploaded 57 packages, and reported:

```
Skipped 0 package versions already attempted under R 4.4; 0 remaining
Skipped 0 package versions already attempted under R 4.6; 3 remaining
```

The same run's index step dropped **2407** packages as missing for 4.4 and **2436** for 4.6. Nothing to build, and thousands missing — the candidate list is wrong.

## Two omissions

**1. Per-minor objects mask the per-minor candidates.**

```r
s3_pkgs <- s3fs::s3_dir_ls(".../latest/src/contrib", recurse = TRUE)
file_names <- basename(s3_pkgs)
```

`recurse = TRUE` walks `4.4/`, `4.5/`, `4.6/`; `basename()` throws the directory away. `4.5/curl_1.0.tar.gz` and `curl_1.0.tar.gz` collapse to one name, so a package present under **any** R minor counts as built for **all** of them — pruning exactly the packages a per-minor pass exists to build.

Per-minor objects are now excluded, and presence in a specific minor is decided downstream where the running R version is known: `build-all.R` filters on it, and `build_binary_package()` checks the per-minor path per package and skips what is already there.

`Archive/` is kept. Those are versions built and later superseded; dropping them would make every archived version look unbuilt.

Validated against real path shapes:

| path | |
|---|---|
| `curl_1.0.tar.gz` | keep |
| `4.4/curl_1.0.tar.gz` | exclude |
| `4.6/rlang_1.3.0.tar.gz` | exclude |
| `Archive/curl/curl_0.9.tar.gz` | keep |
| `PACKAGES.gz` | keep |

**2. The error query ignores `r_version`.**

```sql
SELECT error_occurred FROM single_builds
 WHERE name = $1 AND tag = $2 AND platform = $3 AND arch = $4
```

A failure under the primary minor drops the package from every other minor's candidate list. This is the same omission fixed in `local/build-all.R` (#187) and in bincraft's `check_package_error()` (rpkgs/bincraft#119). This is the third and last consumer of that table — I have grepped the rest; `bincraft::R/cran-internal.R` also reads it, but to list packages present rather than to skip, where the R minor does not apply.

## Expected effect

The per-minor passes get real candidate lists. Expect slots that reported "0 remaining" to report thousands, and correspondingly long runs.

There is a cost: the list is no longer pruned by per-minor presence, so each pass asks `build_binary_package()` about packages that may already exist, and it answers `already exists in S3 ... Skipping build` per package. Slower per pass, and correct — the pruning it replaces was removing the wrong things.
