fix(logger,prompts): replace yoctocolors-cjs rgb() with manual ANSI codes

The yoctocolors-cjs package doesn't have an rgb() method. Replace calls
to colors.rgb() with manually constructed ANSI escape sequences for
RGB colors (ESC[38;2;r;g;bm...ESC[39m).

Affects:
- src/logger.ts applyColor() function
- src/stdio/prompts.ts applyColor() function
