* feat: add minimal NanoKVM image target

Add an SG2002 LicheeRV Nano SD board variant based on sg2002_licheervnano_sd, with its own Buildroot configuration and the matching kernel, U-Boot, device tree, memory map, partition, and board initialization files.

Compared with the standard image, replace the broad Buildroot package set with a NanoKVM runtime allowlist. Remove Python 3 and its Python module collection; FFmpeg, OpenCV, ALSA utilities, mpg123, Tcl, and Expect; games, editors, and interactive tools such as tmux, htop, nano, and vim; GDB, tracing, benchmark, stress, memory-test, and SPI-test utilities; IPMI, serial, U-Boot, LCD, and TPU demo tools; and nonessential archive, compression, and SquashFS utilities.

Also omit general-purpose network and administration tools including aircrack-ng, bind, dnsmasq, iperf3, mosh, mtr, netcat, nftables userspace, pppd, rsync, ser2net, socat, SSDP responder, tcpdump, tinc, traceroute, WireGuard tools, and the standalone watchdog package. Disable unneeded hostapd and wpa_supplicant options such as EAP, WPS, IBSS, Wi-Fi Display, mesh, D-Bus, debug logging, and shared client support.

Keep the NanoKVM essentials: Bash, OpenSSH server and key generation, Avahi mDNS, CA certificates and curl, NTP, Ethernet and Wi-Fi management, iproute2, iptables, filesystem resize and virtual-media tools, AIC8800 firmware, the CVITEK runtime, and SG2002 codec firmware.

Run a post-build cleanup that removes SDK sample and test binaries, static and libtool archives, headers, documentation, man and info pages, pkg-config files, and CMake metadata. Optimize the target for size and reduce the Buildroot ext4 filesystem from 1536M to 192M while leaving the SD partition layout unchanged.

Mark minimal root filesystems so the NanoKVM merge step does not bundle FRP, Tailscale, or tailscaled. Keep their existing installation behavior for standard images, install the SSH init script only when OpenSSH is present, validate required init scripts earlier, and remove incomplete output images after recoverable failures.

Isolate Buildroot output and overlays by project, support board-specific Buildroot defconfigs, clean the matching output directory during rebuilds, and document how to build and merge the minimal image.

* feat: shrink minimal NanoKVM image

- reduce the minimal ext4 rootfs image to 112 MiB
- disable udev hwdb and remove stale ISP tuning blobs
- keep only LT6911 sensor support and remove the unused 8733bs driver
- strip NanoKVM-Server debug sections during image merge without modifying the source app

Validated with the minimal build, complete NanoKVM APP merge, ext4 free-space checks, and boot-area integrity verification.

### 1.6 编译 minimal 镜像
如果需要更小的 rootfs，可以选择 minimal 板型：
```shell
cd "$SDK_DIR"
source build/cvisetup.sh
defconfig sg2002_licheervnano_sd_minimal
clean_all
build_all
```
minimal 产物位于：
```shell
"$SDK_DIR/install/soc_sg2002_licheervnano_sd_minimal/"
```
minimal 镜像不预装 Python3、FRP 和 Tailscale，但保留 NanoKVM、SSH、mDNS、Bash 及基础网络功能。合并 APP 时需要显式指定 minimal 镜像：
```shell
./kvm/merge_nanokvm_app.sh \
-i install/soc_sg2002_licheervnano_sd_minimal/images/your-image-name.img
```
如果编译过程中停在下载进度位置，例如 `Buildroot` 正在下载 `Pillow`、`qt5base`、`qt5svg` 等源码包，通常是网络较慢，不一定是编译卡死。可以观察对应的临时下载文件大小是否仍在增长。
如果首次构建在 `qt5svg` 或 `qt5base` 附近失败，可以先重新执行：

- 自动选择最新生成的原始 `.img`，或者使用你手动指定的镜像。
- 默认复制出一个新的 `*-nanokvm.img`，只修改这个输出镜像，不原地修改原始镜像。
- 挂载镜像的 ext4 分区。
- 写入 `kvmapp`、`frpc`、`tailscale`、`tailscaled`、内核模块、启动脚本、默认数据和默认 KVM 配置。
- 写入 `kvmapp`、内核模块、启动脚本、默认数据和默认 KVM 配置；普通镜像还会写入 `frpc`、`tailscale` 和 `tailscaled`。
- 每个关键步骤后检查挂载状态或目标文件，并校验第二分区之前的 boot 区域没有变化；失败时打印具体失败步骤并终止。
- 写入完成后自动卸载镜像。
