Jakub Zych e903cc32be feat(diary): component loggers through a redacting console and daily stack
- New diary module: For, Bootstrap, Setup, SetVerbosity, Reset, Close, ParseConfig
- Proxy component handler safe in package vars; styled console handler in bonfire's palette
- Daily writer: one file per day, 0640, lazy open, retention, disables itself on open failure
- Every channel leaf wrapped by sunscreen.Wrap; stack via slog.NewMultiHandler
- bonfire: ColorMode, Palette, DefaultPalette, DetectProfile (lipgloss v2, colorprofile)
- Generated main runs diary.Bootstrap first and diary.Setup after compass.Load
- Ignore /storage/ and /examples/hello/storage/
