Issue 1 — flickering during typing/updating:
- Wrap every frame render in DECICM sync (begin-sync/end-sync) so the
terminal defers rendering until the entire frame is written
- Replace backend-clear (ESC[2J full clear) with draw-rect background
fill — eliminates visible blank frame between redraws
- These two changes together eliminate all visible tearing/flicker
Issue 2 — bottom-anchored minibuffer (Emacs-style):
- Replace centered overlay dialog with bottom-anchored minibuffer
that expands upward from the input line
- Unified command menu: Ctrl+P and / both open the same menu with
all 35+ commands (slash + daemon), dispatch by value type
- Filter prompt at h-3 (same position as normal input),
options listed above, grows up to 15 lines
- No full-screen dim backdrop — just clear the minibuffer area
Issue 3 — color schemes:
- Add 5 new presets: catppuccin, tokyonight, dracula, gemini, mono
- Total: 13 presets (up from 8)
- Update /theme completion list and help text
Also fixed: pre-existing unbalanced paren in tui-main (missing close)
