v0.4.2

Added

• Added dynamic elapsed timer to TUI working, compaction, and branch summary status indicators:
  • Loader::withTimer() automatically calculates and formats elapsed duration in the top border: ⠋ Working... · 16s (esc to interrupt) (or · 1m15s after 60s).
  • Provides clear real-time feedback that long-running operations (deep model reasoning, large codebase searches, slow network API calls, and context compactions) are actively executing rather than frozen.
  • Enabled during turns (Working...), manual /compact, tree branch summarization, and auto-compaction, while preserving retry countdowns untouched.
