feat(sdk): 批2 meow_lyric_view 歌词页渲染控件 — 上收ncm成熟布局(活动行纯白/灰阶/偏上锚定/翻译行不叠行/折行/点行seek),布局命中绘制同源,宿主L1-L7全过,预留批5取色set_colors,暂不并入meow_ui.a

/*
|
||||||
|
* meow_lyric_view.c — SDK 通用歌词页渲染控件实现（见 meow_lyric_view.h 的契约说明）。
|
||||||
|
*
|
||||||
|
* 上收自 ncm_app/app/ui/player.c：lyr_layout（活动行块中心偏上锚定、上方 ≥LYR_ABOVE_MIN 行已过、
|
||||||
|
* 下填满、总 ≤LYR_MAX_ROWS）+ plr_draw_lyrics（活动行纯白、上下行逐级灰阶、翻译紧跟随不叠行，
|
||||||
|
* 块高含翻译行是 agent-380 修好 s_lyr_bh 的关键）+ lyrics_line_tap（命中=布局逐块扫描）。折行复用
|
||||||
|
* 批1 meow_lyric_wrap（=ncm lyr_wrap_lines 的通用化），宽度测量经注入的 meow_lyric_width_fn。
|
||||||
|
*
|
||||||
|
* 控件形态：W_CUSTOM 自绘画布（meow_widget_custom_create），render_cb/hit_cb 由本 TU 实现。
|
||||||
|
* 布局（lv_compute_layout）计算结果缓存在 lv->vis[0..vis_n)，绘制/命中/公开查询共用，三者一致。
|
||||||
|
*
|
||||||
|
* 内存纪律：per-instance struct（calloc）；布局数组定长 [MEOW_LYRIC_VIEW_MAX_ROWS]；折行复用缓冲
|
||||||
|
* 一块 [MEOW_LYRIC_VIEW_MAX_ROWS][MEOW_LYRIC_SEG_SZ]（逐条目复用，同 ncm s_lyr_seg 模式）；
|
||||||
|
* 零临时堆分配（meow_lyric_wrap 静态缓冲）。

* meow_lyric_view.h — MeowOS SDK 通用歌词页渲染控件（可复用，供 launcher Now Playing 与 ncm 共用）。
|
||||||
|
*
|
||||||
|
* 定位：把 ncm_app/app/ui/player.c 已成熟（agent-380 修好 s_lyr_bh）的歌词页布局上收成 SDK 控件。
|
||||||
|
* 能力对齐 ncm 歌词页：活动行纯白（居中偏上锚定）、上下行按行距逐级灰阶、翻译行紧跟原文行不叠行
|
||||||
|
* （块高含翻译行）、超宽折行（中西文兼容）、上方保底 ≥above_min 行已过、总视觉行数 ≤max_rows、
|
||||||
|
* 点行 seek 命中与绘制一致（同一布局函数）。
|
||||||
|
*
|
||||||
|
* 数据来源：**绑定批1 meow_lyric**（解析/查询 API：meow_lyric_count/line_at/line_text/line_tl/line_time，
|
||||||
|
* 全局单例，线程安全）+ 播放位置（meow_lyric_view_set_pos）。宽度测量用回调注入
|
||||||
|
* （`meow_lyric_width_fn`，包 meow_ui_text_width 的包装；宿主测试传自己的测量函数）。
|
||||||
|
*
|
||||||
|
* 控件形态：内部持一个 `meow_widget`（W_CUSTOM 自定义画布），经 meow_lyric_view_widget() 取出供
|
||||||
|
* meow_widget_draw/hit/注册；render_cb/hit_cb 都由本控件自绘/自判。App 也可只用纯查询接口
|
||||||
|
* （meow_lyric_view_visible/hit_line）在自绘流程里复用布局逻辑。
|
||||||
|
*
|
||||||
|
* 主题：用 SDK 全局 meow_theme 为默认（明暗背景 scrim、活动行 onSurface=dark 纯白、灰阶递减），
|
||||||
|
* 为批5「封面取色动态主题」预留 meow_lyric_view_set_colors 覆盖入口（字段 0=仍用主题默认）。
|
||||||
|
*
|
||||||
|
* 依赖：纯 SDK（meow_ui.h + meow_lyric.h），不引任何 ncm 私有符号；可链 meow_ui.a 使用，
|
||||||
|
* 亦可宿主 gcc 单测（同 test_now_playing_widgets 链法）。本头为**独立公共头**（仿 meow_ui_view.h
|
||||||
|
* 模式，不随 meow_ui.h 伞头发布），App 显式 `#include "meow_lyric_view.h"`。
|
||||||
|
*
|
||||||
|
* 命名：API 一律 `meow_lyric_view_*`（对齐 SDK 规范）；控件内布局/绘制/命中共享同一
|
||||||
|
* meow_lyric_view_visible 计算，保证「点行 seek 命中与绘制一致」。
