Add alloc_pair(), find_pair(), free_pair() and reset_color_pairs(), wrapping the ncurses extended-color dynamic pair management. They are available only when built against a wide-character ncurses with extended-color support. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Wrap the ncurses extended-color dynamic color-pair management, which the standard :mod:
cursesfunctions cannot express:curses.alloc_pair(fg, bg)allocates a color pair for the given foreground and background colors and returns its number, reusing an existing pair for the same combination. Unlikeinit_pair(), the caller does not choose the pair number.curses.find_pair(fg, bg)returns the number of an already-allocated pair for the given colors, or-1if none has been allocated (the inverse ofpair_content()).curses.free_pair(pair)releases a pair previously allocated byalloc_pair().curses.reset_color_pairs()discards all color-pair definitions at once.All four are available only when Python is built against a wide-character ncurses with extended-color support (the same condition as
curses.has_extended_color_support()).The already-wrapped
init_color/init_pair/color_content/pair_contentalready route to the*_extended_*variants internally, so those extended functions are not exposed under separate names; only the dynamic pair-management functions above add new capability.🤖 Generated with Claude Code
