The Tachyon profiler's curses-based TUI now uses the centralized theming
infrastructure in _colorize.py, enabling users to customize colors via
the standard Python theming API. This adds a LiveProfiler theme section
with two pre-configured themes: the default dark theme optimized for
dark terminal backgrounds, and LiveProfilerLight for white/light
backgrounds. Users can switch themes by calling _colorize.set_theme() in
their PYTHONSTARTUP or sitecustomize.py.
The table header rendering was also improved to draw a continuous
background, eliminating visual gaps between columns when using reverse
video styling.
