IONOS shared hosting enforces a strict process limit. yq (a Go binary)
tries to spawn several OS threads at startup and crashes with
"failed to create new OS thread (errno=11 EAGAIN)" when the limit is
hit, returning empty stdout. This silently skips all references.
Wrap yq with GOMAXPROCS=1 GOGC=off so the Go runtime uses a single
goroutine-running thread and skips GC goroutines, staying within the
host's ulimit -u.

FORCE_COLOR defaulted to 1, emitting ANSI codes unconditionally. On SSH
sessions without a proper TTY or with TERM=dumb this caused color codes
to render text invisible. Now colors are enabled only when stdout is an
interactive terminal; FORCE_COLOR=1 can still override when needed.

All log_* functions were writing to stderr, causing output to be
invisible in SSH sessions where stderr is not forwarded or captured.

Replace broken control characters and U+FFFD replacement characters in
log function labels with ASCII equivalents ([ok], [!], [x]).
Drop the hardcoded "main" default for git_ref so arty deps no longer
fails with "pathspec 'main' did not match" on repos whose default branch
is not named main — git clone already checks out the remote default branch.
A ref: value in arty.yml is still honoured when explicitly set.
