v0.2.1

Added

• New tags_color config option to colorize %tags placeholder output; --no-color automatically
  suppresses the ANSI sequences to prevent stray codes in piped output (see [#421])
• New %*title and %*note template placeholders expand to fill remaining terminal width after
  all fixed-width elements on the line; %min-*title sets a minimum width floor (see [#422])

Fixed

• --back with a clock-only time (e.g. 2:30pm) entered after midnight now resolves to the
  previous day instead of a future timestamp (see [#420])
• Config loading now surfaces errors from current_dir() instead of silently resolving paths from
  an empty working directory (see [#423])
• Arithmetic in search matching and duration parsing now uses checked operations, preventing silent
  integer wrapping on out-of-bounds values (see [#424])
• Interactive fzf output now returns a proper error on invalid UTF-8 subprocess output instead of
  silently replacing bytes (see [#425])
