Summary
这个 PR 主要针对
TG032-MCU这类 MCU 原理图的局部布局进行优化，重点修复 MCU 周边触摸按键 TK 符号显示，以及 MCU 去耦电容 C11 的接地布线样式。修改内容
1. 修复 MCU 左侧 TK 触摸按键符号显示
修改位置主要在：
src/skidl/schematics/topology/mcu.py原来的问题是：
TK_Spring_Center和TK_Spring_Side在生成原理图时显示风格不一致TK2的符号方向和下面几个 TK 不统一本次修改后：
TK2 / TK3 / TK1 / TK4的符号方向保持一致2. 优化 MCU 去耦电容 C11 的 GND_0 接地布线
修改位置主要在：
src/skidl/schematics/topology/mcu.py重点涉及的函数包括：
_mcu_decouple_ground_context_mcu_force_place_decouple_at_signal_pin_mcu_route_decouple_ground_net原来的问题是：
P35/T1/TKCAPGND_0GND_0同时连接 MCU 的VSS本次修改后：
P35/T1/TKCAPGND_0trunkVSS引脚水平接出到这根GND_0trunkGND_0trunk 下方单独挂出3. 保留现有 routing 逻辑
本 PR 没有重写全局 routing 算法。
没有修改：
netlist-to-sch-via-skidl.net文件TG032-MCU.py修改集中在
skidl-pnr-opt的 MCU topology / local routing 处理逻辑中。验证方式
使用
TG032-MCU示例进行验证：打开生成的 schematic：
检查结果：
TK2 / TK3 / TK1 / TK4连接关系保持正确P35/T1/TKCAPGND_0GND_0水平连接到 MCUVSSGND_0trunk 下方接出Scope
本次 PR 只针对 MCU 专用布局中的局部显示和局部布线规则进行修复，主要服务于
TG032-MCU这类 MCU 周边电路的可读性优化。
