feat(security): add a user-writable plugin ingest inbox for cross-account data
The LocalService runner can't traverse the interactive user's profile the way
the old SYSTEM runner could — so a plugin can no longer read a file an app
running as *you* produced (the acute case: the Playnite exporter's library
JSON under %APPDATA%). Confirmed on-glass: as LocalService the glob finds
nothing and the profile is un-traversable.

Add the inverse of plugin-state: <config_dir>\ingest, granted BUILTIN\Users
Modify by plugins enable (disable reverts to inherited Users:RX). An
interactive-user app drops ingest\<plugin>\… and the de-privileged runner
reads it there — the one Users-writable carve-out in the otherwise
Users-read-only tree. SDK exports pluginIngestDir(name) to resolve it; on
Linux the systemd --user runner owns the config dir so same-user producers
write there with no grant.

Accepted tradeoff: the inbox is writable by any local user (trusted-single-
user model; it feeds only a LocalService runner). Consumers must treat ingest
data as lower trust than their own state.
