c08a749043 ffi 0.7: #import c { #include / #source } via stdlib-path resolution
94/94 regression tests pass (+ffi-07-c-import-block).

Companion C helper lives only at
`library/vendors/sx_ffi_resolve_test/`. Critically NOT in
`sx/vendors/` (the sx repo root) and NOT in the importing
example's directory — so the `vendors/...` paths in this
example are findable solely via the stdlib search branch
(`<exe>/../../library`, `<exe>/../library`, `<exe>/library`).

That branch is the one the JNI insets bridge needs to reach
`library/vendors/sx_android_jni/sx_android_jni.c` without
forcing chess (or any consumer) to vendor an identically-named
copy. The test pins the resolution end-to-end:
  - #include  resolves; clang parses the .h; c_import.zig
    synthesizes #foreign fn decls for `sx_ffi_resolve_test_add` /
    `_mul`.
  - #source   resolves; the .c is compiled into the build's
    object list.
  - sx calls the synthesized decls and prints results.

4849cfb904 android: dpi_scale, scissor, JNI safe-insets, touch input
Four Android UX wins landing together; all verified end-to-end on a
Pixel 7 Pro (board fills width, info-panel text renders, status bar
inset honored, tap-to-select + tap-to-move plays 1. e4).

- AndroidPlatform.init reads density via AConfiguration_getDensity
  (app->config at offset 32) and sets dpi_scale = density / 160. The
  hardcoded 1.0 had been making every logical unit equal one physical
  pixel; ChessBoardView's 520-default size_that_fits fallback then
  rendered at ~half the framebuffer width on the device, and glyphs
  rasterized at literal 11-13 physical pixels were essentially invisible
  on a 2340-tall display.
- gles3.sx set_scissor un-stubbed; with dpi_scale right the renderer
  feeds in valid pixel bounds and the Y-flip math lands inside the
  framebuffer.
- New library/vendors/sx_android_jni/sx_android_jni.c walks
  activity -> window -> decorView -> rootWindowInsets via JNI and
  publishes the system-bar insets. safe_insets() lazy-queries the
  first call after EGL is up (decor view isn't attached at bootstrap).
- sx_android_install_input_handler sets app->onInputEvent; sx-side
  sx_android_input_event translates AMotionEvent DOWN/MOVE/UP/CANCEL
  into existing mouse_down/mouse_moved/mouse_up Events so the chess
  board's tap-to-select + ScrollView drag path Just Works. Coordinates
  divided by dpi_scale so layout-side hit tests match. poll_events
  drains its slice after returning (mirrors the SDL pattern).
- src/imports.zig now routes #import c { #source / #include } paths
  through the same chain as #import (importing dir -> CWD -> stdlib
  search paths). Lets library-owned C helpers like the JNI bridge
  live in sx/library/vendors/ without forcing consumers to vendor a
  copy. Existing CWD-relative consumer layouts (chess's vendors/...)
  still resolve first, so no regression.

86/86 regression tests pass.
