PWR_FLAG instances use a #FLG reference prefix, not #PWR, so their
pin positions were never registered as virtual connection anchors in
_parse_virtual_connections. As a result, find_orphaned_wires reported
wire ends terminating on a PWR_FLAG as dangling. Other call sites
(schematic_analysis.py:127, kicad_interface.py:3814) already recognize
#FLG as a power symbol; align this site with them.
Also coerce a previously-validated Optional[int] to int in board/layers.py
so the file passes mypy (required by the pre-commit hook); behavior is
unchanged because the value is already None-checked above.

board.GetLayerStack() was removed in KiCad 9. Call SetLayerName and
SetLayerType directly on the board instead, and grow the copper layer
count via SetCopperLayerCount when adding inner layers. Without this,
add_layer raises AttributeError on any KiCad 9 installation.
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.

Add .pre-commit-config.yaml with pre-commit-hooks v5.0.0 (trailing
whitespace, end-of-file fixer, yaml/json checks, large file guard,
merge conflict detection). Add minimal pyproject.toml. Auto-fix
trailing whitespace and missing end-of-file newlines across the
codebase.
