Nightly AppImage: symbol library path not set correctly
# Description The default settings for the nightly app image specify the wrong location for the symbol library. This leads to the symbol library being empty by default. * The default path is: `/usr/share/kicad/template/sym-lib-table` * The default path should be: `${KICAD10_SYMBOL_DIR}/../template/sym-lib-table` (or something else relative to the kicad installation). # Steps to reproduce 1. Run nightly appimage "for the first time", and don't import settings from prior kicad installation. 2. Create new project. 3. Open schematic. 4. Attempt to add "GND" or some other default symbol. # KiCad Version ``` Application: KiCad Schematic Editor x86_64 on x86_64 Version: 10.0.0-rc1.1-43-ge73caa3b2c, release build Libraries: wxWidgets 3.3.2 FreeType 2.13.3 HarfBuzz 6.0.0 FontConfig 2.14.1 libcurl/8.14.1 GnuTLS/3.8.9 zlib/1.3.1 brotli/1.1.0 zstd/1.5.7 libidn2/2.3.8 libpsl/0.21.2 libssh2/1.11.1 nghttp2/1.64.0 librtmp/2.3 OpenLDAP/2.6.10 Platform: Ubuntu 25.10, 64 bit, Little endian, wxGTK, Wayland, ubuntu, wayland, AppImage Build Info: Date: Feb 14 2026 06:29:43 wxWidgets: 3.3.2 (wchar_t,STL containers) GTK+ 3.24 Boost: 1.74.0 OCC: 7.9.1 Curl: 7.88.1 ngspice: 45.2 Compiler: GCC 12.2.0 with C++ ABI 1017 KICAD_IPC_API=ON KICAD_USE_PCH=OFF Locale: Lang: en_US Enc: UTF-8 Num: 1,234.5 Encoded кΩ丈: D0BACEA9E4B888 (sys), D0BACEA9E4B888 (utf8) ```
