internal/log now logs through log/slog. After Init, records go to a small slog.Handler that prints the same lines as before, colored by the same rule; before Init they go to slog.Default(). Level filtering, the helpers and their call sites are unchanged. With NO_COLOR set on a terminal, log lines are no longer colored. pterm is dropped: mfer used it only to print progress lines to the configured stdout, which fmt now does directly, outside slog. apex/log, pterm and their indirect dependencies leave go.mod; golang.org/x/term, already in the module graph, becomes direct. simplelog is not used: its handler writes to stdout and would change the CLI's output. The logger stays process-global, since injecting it would change package mfer's API. Model: opus-5-5
