feat(ui): add colored, structured CLI output
Replace flat "info:" / "warning:" stderr lines with:
- logStep (·), logDone (✓), logWarn (!) prefix symbols
- ANSI colors when stderr is a TTY; auto-disabled via NO_COLOR or TERM=dumb
- Verbose mode uses ▸ section headers (configuration / branch / commits / version)
- Config table source tags colored: dim=[default], bold=[config file],
  cyan=[env:], green=[flag:]
- Commit table in verbose mode: type column colored by kind (cyan=feat,
  green=fix, red=breaking), ignored commits dimmed
- New cmd/ui.go holds all color helpers (paint, logStep, logDone, logWarn,
  logSection, fmtSource); removes the vlog() helper
