- Record the package, version and artifact of a push in one transaction
that only inserts the artifact if no pushed copy exists. Of two
concurrent pushes of the same file exactly one wins, and the loser's
version integrity is rolled back with it.
- Check for an existing file before reading the request body, and send
Expect: 100-continue from proxy hosted push, so a refused re-push isn't
uploaded first.
- Leave an existing version record alone for multi-file ecosystems, so a
generic push doesn't reset a version cached from upstream.generic.
- Reserve the upstream.generic name "hosted" only while hosting is
enabled, and only intercept /generic/hosted/ then.
- Accept a file argument in proxy hosted delete for generic only.
- Mark multi-file ecosystems explicitly, and give parse a min/max range.
Hosted ecosystems are now entries in one table: each defines its package
names, how the stored filename is chosen, how the manifest is read and which
namespaces are served from pushes alone. npm and Composer move there
unchanged, and generic is added as a third entry.
Generic files are pushed to /api/hosted/generic/{name}/{version}/{file}
and served without a token from /generic/hosted/{name}/{version}/{file},
with the sha256 as ETag. They have no manifest, a version can hold several
files, and they never come from an upstream. "hosted" is reserved as an
upstream.generic name. DELETE with a file removes only that file.
For all hosted ecosystems:
- A second push of the same file is refused with 409. Clients pin pushed
files by version and often by hash, so a published file is no longer
silently replaced. Delete it first to push it again.
- PUT takes an optional ?sha256= and refuses bytes that don't match.
proxy hosted push always sends it.
Versions of generic files carry no version-level integrity, since it could
only describe one of their files; each file is checked against its own
sha256.

proxy list and proxy delete sat next to serve, stats and mirror and read as cache operations. The commands are now proxy hosted push, proxy hosted list and proxy hosted delete, before a release makes the names hard to change. proxy hosted without a known subcommand prints the three.
Refs #133
proxy push, proxy list and proxy delete call the /api/hosted endpoints of a running proxy. The proxy URL comes from -url or PROXY_URL and the token from PROXY_HOSTED_TOKEN, so it never ends up in shell history or process listings.
Document the hosted config block, the endpoints, the supported ecosystems and how pushed archives interact with eviction.
