Two things a local install should not have asked for. `fluksio serve` now signs you in. Logging in to your own machine was a formality — the password was printed by the same process that would have checked it, and the database it authenticates against sits in the directory the token goes into — so `serve` mints the token itself and says where it put it. `fluksio login` is left for an engine somewhere else. And an installation is `.fluksio` beside the code, found the way `.git` is, rather than one `~/.fluksio` for the machine. A repository with its own venv was already getting its own engine; it now gets its own flows, run history and token too, instead of three repositories sharing one database and fighting over one port. `--global` asks for the shared one, `--data-dir` still names any directory, and when both exist the banner says which you are looking at and how to reach the other. The directory ignores itself from within — a `.gitignore` of `*`, the way uv writes one into `.venv` — because it holds a credential and a database, and neither belongs in anybody's history. The token is written mode 600. A login an older version wrote to ~/.config/fluksio is still read, so nothing that worked stops working.
