mckero a654735337 merge: upstream rt-bishop main (18 commits) with conflict resolution 
Merges rt-bishop/Look4Sat main (a42a5f1f, 18 commits: AMSAT status page,
customizable data sources, Doppler calculator, radar compass offset, per-sat
offset memory, localized date formats) into the fork's 30-commit audit
baseline.

Conflict resolution policy (user-directed):
- AMSAT feature (AmSatRepository, SatStatusScreen/ViewModel, SatStatus model):
  upstream version, which the user judged better built. MainScreen routes
  Screen.AmSat through SatStatusDestination().
- Localization: our values-zh/values-tr restored (upstream's merge dropped the
  fork-only strings); new upstream strings (sat_group counts, compass offset,
  frequency offset help) added in EN + ZH.
- fork-only features kept (CW decoder, Mutual/Roaming, WaveLog, APRS, Log tab,
  custom TLE/transceiver source switches): ours.
- Both sides' additions merged where independent: radar compass offset fields
  (Settings/SettingsRepo/RadarState), calculatorOffsetKHz action, wider linear
  transponder detection, deduplicateTransponders + its tests, sunrise/sunset
  tests merged with the moon hour-angle test.
- Sources kept as the fork's map structure (DatabaseRepo depends on it);
  satelliteModes list re-added for SelectionRepo. getSatelliteTypesIds /
  setSatelliteTypeIds re-added to ISettingsRepo+SettingsRepo; SharedDialog
  re-added to Components; providePairedBluetoothDevices added to
  IMainContainer/MainContainer.
- Icons renamed upstream (ic_satellites->ic_sputnik, ic_radar->ic_satellite)
  applied to Navigation/MutualScreen.

Build verified: all modules compileReleaseKotlin + unit tests
(core:domain, core:data, feature:map, feature:roaming) green.

mckero f4f6ec7db5 feat(cw): ship the full fp32 DeepCW model instead of the int8 build 
用户要求内置完整版模型, 不要量化版。

assets/deepcw/model.onnx: 4,354,478 bytes (int8) -> 15,139,839 bytes (fp32)
sha256 ef120799457bca042d4690944f0faf93268eb4654e7f50f28784ad63bdc1fe02,
与上游 commit 8e264d2 发布的原始文件逐字节一致, 零修改。

实测验证(直接对仓库内的 asset 跑推理, 35 个场景):
- 信噪比: 干净 ~ -6 dB 全部逐字符正确; -9 dB 起显著劣化
- 速度: 12-45 WPM, 8 档中 7 档零错误 (40 WPM 推理仅 167ms)
- 音调: 450-1150 Hz 全窗口 6/6 零错误
- 频率漂移: +20/+60/+150/-300 Hz 全部 4/4 零错误 (卫星多普勒无忧)
- QSB 衰落: 6/12 dB 无损, 20 dB 深衰落 CER 23.5%
- QRM 同频干扰: 4/4 失败(会把干扰台内容一起解出), 全频段模型固有特性,
  实用时依赖电台窄带 CW 滤波器缓解
- fp32 vs int8 准确率打平(5 档中 4 档完全一致); 服务器 x86 上 fp32 推理
  耗时约为 int8 的一半(int8 动态量化的反量化开销在无 int8 加速指令的 CPU
  上反而更慢)。手机 ARM 侧表现待装机确认。

NOTICE.md / DEEPCW.md / README.md 同步更新: 移除 int8 量化派生的记录与复现
步骤, 改为声明未修改照搬上游。

代价: APK 体积约 59MB -> 70MB, 运行内存峰值上升。此前真机闪退的根因是 R8
缺 -keep ai.onnxruntime.** 规则(已修), 与模型大小无关。

mckero d6b61eaa4b license: switch the root LICENSE to AGPL-3.0 for the combined work 
用户指出 GitHub 上显示的许可证仍是 GPL-3.0,未反映合并 AGPL 组件的事实。

根因: 之前只在 README 加了 License 章节,根 LICENSE 文件仍是 GPL-3.0 原文,
GitHub 的自动检测(只扫 LICENSE 文件)自然还是 GPL-3.0。

修复: 合并作品按 GPL-3.0 §13 / AGPL-3.0 §13 处理,根 LICENSE 改为:
- 顶部 LICENSING NOTICE 说明构成 (Look4Sat 代码 GPL-3.0 + DeepCW 模型
  AGPL-3.0-only, 合并作品按 AGPL-3.0 分发)
- 正文为 AGPL-3.0 原文 (从 DeepCW-AGPL-3.0.txt 复制)

原 GPL-3.0 原文保留在 feature/cw/licenses/Look4Sat-GPL-3.0.txt。
README License 章节同步更新,与新 LICENSE 一致。

此后 GitHub 侧边栏将识别为 AGPL-3.0。

mckero 2e1d8b9c00 feat(cw): archive decoded history, polish the waterfall, document licensing 
三个用户反馈一并解决:

1. 解码文字不再消失 (核心)
   旧实现: 20 秒环形缓冲满了就静默覆盖最旧样本, 文字随之从屏幕消失。
   新实现: CwDeepBuffer 新增 overflow —— 满时被覆盖的旧样本先进 overflow,
   解码器累积到 15 秒就单独解码一次, 结果追加到 historyText (只增不减)。
   UI 记录区显示 historyText + decodedText (历史稳定 + 当前窗口实时)。
   ICwDecoder 接口新增 historyText StateFlow。

   归档音频已离开主窗口, 不再被 CTC 修正, 故其文本是"最终版", 追加安全。
   归档窗口 15 秒: 内容已在 20 秒窗口里解过多次, 短一点几乎无损, 且推理
   开销小。

2. 瀑布图更好看
   配色从"深蓝->青->黄"换成 matplotlib inferno (黑->紫->品红->橙->黄),
   与静态频谱图保持一致。相邻 bin 之间用水平渐变做线性插值, 消除 65 列
   离散方块的像素感。

3. AGPL 合规补漏 (用户提醒: 仓库许可证没体现 AGPL 组件)
   README 新增 License 章节: 声明项目主体 GPL-3.0 + feature/cw 的 DeepCW
   模型 AGPL-3.0-only, 并说明合并作品按 GPL-3.0 §13 / AGPL-3.0 §13 处理。

验证:
- :core:domain:test => 31 个 CW 测试全绿 (CwDeepBufferTest 新增 3 个
  overflow 归档测试: 顺序/清空/reset)
- :core:domain:compileKotlin + :core:data + :feature:cw:compileDebugKotlin
  => BUILD SUCCESSFUL
