When moving a schematic component, connected wires are stretched/shifted
to follow the component (like KiCAD's drag behaviour), preserving
connectivity instead of leaving dangling wire stubs.
Also fixes property labels (value, reference, etc.) so they shift with
the symbol rather than staying at their original positions.

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.

Library symbols use y-up coordinates while schematics use y-down. The
_transform_local_point function was not negating y, causing asymmetric
symbols (e.g. power:VEE) to have their bounding boxes computed in the
wrong direction — missing overlaps with adjacent components.

KiCad's native ERC already checks for unconnected pins with better
accuracy (hierarchical sheets, bus connections, custom rules). Remove
the reimplemented version and its dead helper _parse_no_connects.

Parse graphical elements (rectangle, polyline, circle, arc, bezier) from
lib_symbols definitions to compute accurate symbol bounding boxes instead
of relying on pin positions with hardcoded degenerate expansion. This
fixes bbox accuracy for ICs (previously too small), tiny 2-pin passives
(previously too large), and single-pin symbols.

Eliminate repeated file parsing by extracting _extract_lib_symbols helper
that walks already-parsed sexp_data once instead of re-reading the file
per symbol via PinLocator. Support diagonal wire overlap detection using
cross-product parallelism and 1D projection. Fix wire region inclusion to
use AABB intersection for pass-through wires. Normalize view region
coordinates. Clarify tolerance docstrings across Python, TS, and schema.

Wires that start at a component pin but continue through the body were
incorrectly suppressed as "valid connections." Now nudges the pin endpoint
toward the other end and re-tests intersection — if the shortened segment
still hits the bbox, the wire passes through and is flagged.
Renamed the tool from check_wire_collisions to find_wires_crossing_symbols
across all layers (Python, handler, schema, TypeScript) to clarify that it
finds wires crossing over component symbols, which is unacceptable in
schematics.

The overlap detection was comparing center-to-center Euclidean distance with
a 0.5mm tolerance, missing components whose bodies physically overlap but have
different centers (e.g. a resistor placed inside an opamp triangle). Now uses
AABB intersection on pin-derived bounding boxes, matching the approach already
used by check_wire_collisions. Extracted shared bbox logic into
_compute_symbol_bbox_direct and _aabb_overlap helpers.

Previously, the endpoint suppression logic skipped any wire where at least
one endpoint touched a pin, hiding the case where both endpoints are pins
of the same component (a direct pin-to-pin short through the body).
Replace the single endpoint_matches_pin loop with separate start_at_pin /
end_at_pin checks; suppress only when exactly one endpoint is at a pin.
Add regression test to cover this case.

PinLocator.get_all_symbol_pins resolves symbols by reference designator,
so when multiple components share the same unannotated reference (e.g. "Q?"),
it always returned the first match's pin positions. Every duplicate then
got an identical bounding box, causing a single wire to be flagged against
all N instances instead of only the ones it actually crosses.
Fix: add _compute_pin_positions_direct() that computes absolute pin positions
directly from each symbol's own (at x y rotation) and (mirror ...) data plus
pin definitions fetched by lib_id — no reference-name lookup involved.
Also extend _parse_symbols to capture mirror_x/mirror_y flags.
Add regression test: two "R?" at different positions, wire crossing only
one → must produce 0 collisions against the far-away component.

Add five new read-only schematic analysis MCP tools:
- get_schematic_view_region: export cropped schematic region as PNG/SVG
- find_unconnected_pins: list pins with no wire/label/power connection
- find_overlapping_elements: detect duplicate symbols, stacked labels, collinear wire overlaps
- get_elements_in_region: list all symbols/wires/labels in a bounding box
- check_wire_collisions: detect wires passing through component bodies
Includes Python handler dispatch, tool schemas, TypeScript server bindings,
the schematic_analysis command module, and a full test suite (28 tests passing).

Auto-detects runtime: Java 21+ direct or Docker/Podman fallback.
Discovers docker/podman via PATH instead of hardcoding.
README includes one-time setup with JAR download + Docker pull.

export_dsn, import_ses, check_freerouting. Requires Java 11+ and
freerouting.jar. Includes 21 test cases and README usage examples.
- Add python/tests/conftest.py with MagicMock stubs for pcbnew/skip
- Add python/tests/test_schematic_tools.py with 29 tests covering
WireManager.delete_wire, WireManager.delete_label (unit + integration),
and parameter validation for all 11 new _handle_* methods
- Apply black formatting to component_schematic.py, wire_manager.py,
and kicad_interface.py

The handler used a line-by-line regex requiring (symbol and (lib_id on
the same line, but KiCAD's file writer places them on separate lines.
Replace with the content-string approach (already used by edit handler)
so \s+ matches across newlines. Add regression tests covering inline,
multi-line, and power symbol (#PWR) cases.

- New `get_schematic_component` MCP tool returns component position and
all field values with their label (at x/y/angle) positions
- Extends `edit_schematic_component` with optional `fieldPositions` dict
so callers can reposition Reference/Value/etc. labels in one call
- Adds 18 tests (6 unit, 12 integration) covering parsing, round-trips,
and edge cases
