Simplify the public API into one dense header
yasl.h now holds everything except Vulkan: 45 functions instead of 62,
and three installed headers instead of ten.
- One constructor: yasl_surface_create takes CPU, GL or NATIVE, with
zero-initialized GL options meaning 3.2 core, RGBA8, D24S8.
- Events carry action, mods, x, y and text at the top level; pen
positions are now logical like pointer positions.
- yasl_cpu_pixels/yasl_cpu_present draw into one persistent canvas,
cutting three full-frame copies per frame.
- yasl_surface_get_info, yasl_surface_request, YASL_CURSOR_LOCKED,
yasl_surface_set_text_input, yasl_surface_begin_move_resize and
yasl_surface_get_native replace groups of narrower calls.
- Interactive calls drop the decorative trigger event argument.
- yasl_wait_event returns 0 only on timeout or yasl_wake, the refresh
callback runs only in native modal loops, focus loss sends
INPUT_RESET, and a lost event no longer fails every later wait.
- Unsupported operations and bad arguments report ENOTSUP and EINVAL
instead of EIO; the keycodes header no longer needs C23.
- The shared library gets a versioned SONAME and version macros.
