v0.2.0

talk v0.2.0

Legible palette + XDG config dirs.

- Readable on dark terminals: the rust palette is re-tuned (WCAG-contrast tested) and
  the question no longer paints at the dimmest tone.
- Pinnable palettes: rust (default) · high-contrast · mono (terminal-native), via
  --palette or the config, plus NO_COLOR / TERM=dumb support.
- Config and state moved to XDG dirs: config.toml -> ~/.config/talk, state + streak ->
  ~/.local/share/talk (honoring $XDG_CONFIG_HOME / $XDG_DATA_HOME), so ~/talk holds only
  your reflections. No migration — if you had custom config in ~/talk, move it to
  ~/.config/talk.
