`BaseStore#download` and `download!` previously returned open `File`
objects via `get_from_cache` (which called `File.open`). Nearly all
callers (14 of 16) only needed the `.path` and never closed the handle,
leaking file descriptors. Under load this can exhaust FDs and crash
with `Errno::EMFILE`.
This commit changes `download` and `download!` to return file path
strings instead of `File` objects. Since the cached file at
`tmp/download_cache/` persists on disk, callers that need to read
content can simply use `File.read(path)`.
The public API is simplified to two methods:
- `download`: safe, rescues all errors and returns `nil` (absorbs
the former `download_safe` behavior)
- `download!`: raises `DownloadError` on failure
A deprecated `download_safe` alias is kept for plugin compatibility.
The block/yield pattern is removed entirely since it's no longer needed.
There are no file handles to manage. All call sites are updated to
use the path directly, dropping `{ |f| f.path }` blocks. The two
callers that actually read file content are updated:
- `static_controller.rb` → `File.read(path)`
- `digest_rag_upload.rb` → `File.open(path)` (streams content)
