## BitLogger Update Changes

version 0.4.0

### Feature

- feat: add `ColorMode = Never | Auto | Always` for text formatter color control
- feat: add ANSI level, target, timestamp, and field rendering to `format_text(...)`
- feat: add `color_mode` to `TextFormatter` and `TextFormatterConfig`
- feat: support `text_formatter.color_mode` in JSON config parsing and serialization

### Test

- test: cover ANSI text formatter rendering in `Always` mode
- test: cover `Auto` mode fallback behavior when `NO_COLOR` is present
- test: cover config parsing and serialization for `color_mode`

### Example

- docs: add `color_mode` usage examples to formatter documentation

### Notes

- `Auto` currently uses a conservative rule: if `NO_COLOR` exists, ANSI is disabled; otherwise ANSI is enabled
- this batch only covers ANSI formatter output and does not yet include inline style markup or tag registry support
