215: meow_font.c 流式分块解码(gbk峰值40→23.5MB, 逐字节校验一致) + 多字体槽5→4+16MB驻留预算; 量化: gbk稳态驻留17.3MB vs common 4.2MB(OOM主因); meow_font.a→67113c03 meow_ui.a→223d5401 216: bootmenu让位(sysui在则start launcher让位, 不在则exec兜底) + S70预置launcher.conf enabled=1(+旧设备升级迁移); launcher崩溃可自动拉起; bootmenu 4441822d / S70 e435affc / S90 e0ace111 216注: S70早启动与选单共存为真机重点观察项

* test_budget.c — 宿主校验 meow_font_config_multifont 的「打包面内存预算」：
|
||
* slot0=common（≈4.2MiB）+ 给 CJK 类别装 gbk（≈16.6MiB）→ 合计 > MEOW_MULTIFONT_MEM_BUDGET
|
||
* → gbk 应被拒绝（distinct=1，truncated=1），防止大字库 + 多字体双驻留 OOM。
|
||
* 用法：gcc -I. test_budget.c meow_font.c -lz -o test_budget
|
||
* ./test_budget <common.png> <common.idx> <gbk.png> <gbk.idx>
