Abdessamad Derraz ece637d52d feat: let a profile state that its upstream is gone
Saying those profiles would stay open no matter what was wrong. A dead
forge is a verifiable fact, and a fact can be recorded: upstream_gone
carries why, and the profile stops being an open problem. The refs
describe the last revision anyone could reach, which is all any reader
can ask of them.

The declaration is guarded rather than trusted, because a forge can come
back and a profile that keeps asserting a death nobody rechecks is worse
than one that fails loudly. Declared and unreachable reports as a
recorded fact; declared and answering reports as the contradiction it
is, and the profile has to be read again.

yuzu and suyu carry GitHub's 451. citron carries the loss of
git.citron-emu.org and the squatter now sitting on the .com. Each names
what was probed and when, so the next reader retraces it rather than
repeating it.

notes: |
Yuzu is the original standalone Nintendo Switch emulator, created by bunnei (author of Citra).
Legally shut down by Nintendo in March 2024 via lawsuit settlement. Permanently frozen.
dev.keys can be used instead of prod.keys when use_dev_keys is enabled (for Switch dev units).
Firmware (system NCAs) must be installed through Yuzu's UI from a firmware directory.
Required for commercial games. Homebrew (.nro, .nso) can run without keys or firmware.
Community forks: Citron, Suyu, Eden. Original GitHub repos DMCA'd.
