feat: editor-independent build setup for VS Code, CLion and plain CMake - #536

Conversation
A plain idf.py build (no board fragment) fell back to ESP-IDF's stock 2 MB flash and 1 MB single-app partition table. The 1.24 MB app overflowed it and the table had no static0 partition, which the staticfs target then tried to size from an unset variable because the guard compared an undefined CMake variable name to the empty string. Set the 4 MB flash and the ota_4mb.csv table in sdkconfig.defaults, which every board already uses, and quote the guard so a missing static0 skips the target with the intended warning. dependencies.lock picks up json_generator 2.1.0 from idf.py update-dependencies.
- scripts/utils/idfenv.py finds an ESP-IDF registered by the Espressif installer (eim_idf.json) and applies its activation environment. scripts/build.py uses it when IDF_PATH is unset and sets PYTHONUTF8 for idf.py, so builds work from a plain Windows terminal. - The root CMakeLists.txt derives chip and sdkconfig layers from boards/<board>.defaults when given only OPENSHOCK_BOARD, activates ESP-IDF itself when the shell did not, and hands ninja and the compiler directory to the bootloader's nested configure. CMakePresets.json (generated by scripts/gen_cmake_presets.py, drift-tested) has a configure and build preset per board for CLion and `cmake --preset`. - scripts/idfenv.sh and scripts/idfenv.bat export the same environment for a shell or as a CLion toolchain environment file. - .vscode/ is tracked: tasks through scripts/build.py, clangd settings and extension recommendations. .clangd reads build/compile_commands.json, which the build script refreshes from the last build. - docs/DEVELOPING.md documents toolchain setup, building, testing, editor setup and every dependency update path; README's Contribute section links to it.
requirements.txt pins cryptography above what ESP-IDF 6.1 constrains, so installing it into the IDF venv breaks activation. Point developers at a separate venv and note littlefs-python as the one package staticfs needs in the IDF venv.

Review comments at @.clangd:
- Line 7: Update the CMake preset workflow so each board preset publishes its
generated compilation database to the build directory configured by
CompilationDatabase in .clangd, ensuring clangd uses the current preset’s
commands rather than a stale database.
Review comments at @.vscode/settings.json:
- Line 6: Replace the hard-coded compile-commands directory in clangd.arguments
with a workspace-relative path to the build directory so clangd uses the
compilation database for the current checkout.
Review comments at @.vscode/tasks.json:
- Line 90: Update the script-check and frontend-check task sequences in the VS
Code task configuration to run in order without relying on `&&`, which Windows
PowerShell 5.1 cannot parse. Use ordered VS Code task dependencies or a
shell-independent runner, preserving the existing checks.
Review comments at @docs/DEVELOPING.md:
- Around line 155-156: Update the ESPPORT flash and monitor examples in the
development guide to include equivalent PowerShell and cmd.exe syntax, or
clearly mark the existing inline-assignment commands as POSIX-only.
- Line 72: Update the virtual-environment setup instructions in the developing
guide to show separate executable commands for POSIX, PowerShell, and cmd.exe.
Use the PowerShell activation script for PowerShell and the batch activation
script for cmd.exe; keep each shell’s setup and installation commands in its own
block.

idf.py in ESP-IDF 6.1 configures with a CMake preset whenever a CMakePresets.json exists: the one named 'default', else the first in the file. The first was the hidden 'openshock' base, which CMake refuses, so every build through scripts/build.py failed in CI and locally. Rename the base preset to a visible 'default' with no board; the script's -B and -D arguments override its binaryDir and cache, so idf.py builds are unchanged and `cmake --preset <board>` still inherits from it. A test pins the name and visibility so the failure cannot come back silently.
- Publish build/compile_commands.json from the build itself, so a `cmake --build --preset <board>` feeds clangd like scripts/build.py does - Drop the absolute --compile-commands-dir from .vscode/settings.json; .clangd already names the directory relative to the repo - Split the check tasks into sequenced dependencies instead of `&&`, which Windows PowerShell 5.1 cannot parse - Document venv activation and ESPPORT for PowerShell and cmd - Replace the README's PlatformIO flashing sentence with the current flow
idf.py configures with CCACHE_ENABLE, and ESP-IDF then sets the compile launcher to the bare word `ccache` although it found the program at an absolute path. Outside an exported shell, CLion and a plain `cmake --build --preset <board>` on that tree failed every compile with "CreateProcess failed: The system cannot find the file specified". Set RULE_LAUNCH_COMPILE to CCACHE_FOUND after project(), so the rules carry the full path and the same tree builds from any editor.
One change file per change on the branch: the editor-independent build setup (added), the partition table for a build without a board fragment (fixed) and the json_generator bump (chore). The guide now says that every build publishes the compile database and that a script-configured tree keeps ccache when CLion or a bare shell builds it.
