Viktor Barzin 147a8cff40 Restore f1-stream stack — undo accidental bundling into 63fe7d2b
Commit 63fe7d2b (fan-control) was made with a bare `git commit` in the
shared infra working tree and inadvertently swept in a parallel session's
staged f1-stream-extraction work (main.tf repoint, ~48 files/ removals,
ci-cd.md + .claude docs, two extraction plan docs).

This returns every f1-stream-related path to its pre-63fe7d2b state
(3493c347) so that extraction can be committed cleanly by its own
session. The fan-control files added in 63fe7d2b are untouched.
