/**
 * Color output with automatic terminal capability detection.
 *
 * Four tiers, picked once at import time (cached):
 *   - truecolor  (24-bit RGB)  ← COLORTERM=truecolor|24bit, iTerm2, modern terminals
 *   - ansi256    (256-color)   ← TERM contains "256"
 *   - ansi16     (16-color)    ← any "TERM" ending in "color" or common Unix TERMs
 *   - none       (monochrome)  ← NO_COLOR=1, TERM=dumb, or piped output without FORCE_COLOR
 *
 * Override with FORCE_COLOR=0|1|2|3 (std convention) or CODACHI_COLOR=truecolor|256|16|none.
