Input widget colors no longer hardcoded to Color::White / Blue /
Yellow. New instances use Color::Reset as a sentinel meaning
'use the theme token', and render() falls back to:
- fg: theme.foreground
- bg: theme.background
- cursor_color: theme.warning
Callers that explicitly call .fg() / .bg() / .cursor_color() still
override the sentinel — existing API surface preserved.
Changes:
- input.rs::Input::new() defaults fg/bg/cursor_color to Color::Reset
- input.rs::Input::render() resolves Reset → theme token
- New pub fn cursor_color(c) builder (was missing; .fg/.bg existed)
Tests (2 new in widget::input::tests):
- default_colors_are_reset_sentinel
- explicit_color_overrides_reset_sentinel
Total: 1268 passing (was 1266; +2 new).
