JLCPCBPartsManager defaulted db_path to a "data/" directory computed
relative to __file__, which fails with read-only filesystems when the
package is installed to a system-managed prefix (e.g. /nix/store, an
immutable container image, or /usr/lib). The same pattern in
download_jlcpcb.py would silently scatter the ~1.5 GB JLCPCB cache
inside the install tree even when it is writable.
The original integration plan (docs/archive/JLCPCB_INTEGRATION_PLAN.md)
called for a per-user database under ~/.kicad-mcp/. This change moves
the default to the platform-appropriate user data directory by adding
a new PlatformHelper.get_data_dir() helper that mirrors the existing
get_config_dir() / get_cache_dir() conventions:
- Linux: XDG_DATA_HOME/kicad-mcp or ~/.local/share/kicad-mcp
- macOS: ~/Library/Application Support/kicad-mcp
- Windows: %USERPROFILE%\.kicad-mcp\data
Both JLCPCBPartsManager and download_jlcpcb.py now resolve their
database paths through this helper. ensure_directories() and
detect_platform() include the new directory. Unit tests parallel to
the existing config_dir/cache_dir cases cover platform-appropriate
paths and the relative-XDG_DATA_HOME edge case.
KiCad 10.0 on Windows ships pcbnew.py under bin/Lib/site-packages rather
than the lib/python3/dist-packages path used by KiCad 9.x. Without this
path the MCP server's Python process fails to import pcbnew and exits
immediately with "Failed to import pcbnew module - KiCAD Python API not found".
Changes:
- Prioritise 10.0 in the version list so the newer path is checked first
- Add bin/Lib/site-packages check before the existing lib/python3/dist-packages
check for every version, so both layouts are supported side-by-side
Note: the pcbnew extension is compiled against KiCad's bundled Python 3.11,
so callers must also set KICAD_PYTHON to the KiCad python.exe
(C:\Program Files\KiCad\10.0\bin\python.exe) to avoid a DLL version
conflict when the system Python differs.

Mechanical application of the `.gitattributes` rules from the prior commit.
All 50 files differ only in line endings — verified by
`git diff --cached --ignore-all-space` being empty.
Before: main had 42 CRLF + 27 LF Python files plus mixed-ending in YAML,
templates, and shell scripts. After: every text file is LF (except the
Windows-native *.ps1, *.bat scripts which remain CRLF per gitattributes).
This eliminates the noisy-diff failure mode seen in PR #102, where a
small logic change produced a 918-line diff due to whole-file CRLF→LF
conversion.
Add isort configuration (profile=black, line_length=100) to pyproject.toml,
add isort pre-commit hook, and auto-sort imports across all Python source files.

Add [tool.black] config to pyproject.toml and Black hook to
.pre-commit-config.yaml (rev 26.3.1), then auto-format all Python
source and test files with line-length=100, target-version=py310.
