Promotes BOM / sourcing fields (MPN, Manufacturer, DigiKey_PN, LCSC,
JLCPCB_PN, Voltage, Tolerance, Dielectric, ...) to first-class citizens
on placed schematic symbols.
New MCP tools:
- set_schematic_component_property: add or update one custom property
on a component (convenience wrapper around edit_schematic_component).
- remove_schematic_component_property: delete one custom property.
The four built-in fields (Reference, Value, Footprint, Datasheet) are
protected and rejected.
edit_schematic_component enhancements:
- New `properties` parameter: map of property name to either a string
value or a full spec object { value, x?, y?, angle?, hide?, fontSize? }.
Adds the property when missing, otherwise updates the existing field
(and optionally its label position / visibility). Lets a single tool
call attach an entire BOM payload to a component.
- New `removeProperties` parameter: list of custom property names to
delete in the same call.
- Property values are now backslash-escaped so descriptions containing
a double-quote or a backslash no longer corrupt the .kicad_sch file.
- New properties default to (hide yes) so they appear in BOM exports
without cluttering the schematic canvas.
get_schematic_component description clarified to highlight that it
already returns every field on the symbol, including custom ones.
New MCP prompt component_sourcing_properties guides agents through the
conventional property names recognised by downstream BOM tooling and
the recommended call sequence.
Implementation (python/kicad_interface.py):
- _PROTECTED_PROPERTY_FIELDS frozenset
- _escape_sexpr_string / _find_matching_paren static helpers
- _set_property_in_block / _set_hide_on_property /
_remove_property_from_block surgical text-level edits that preserve
formatting and the property's UUID
- _handle_edit_schematic_component rewritten to orchestrate
add/update/remove and return a per-property summary
- New handlers _handle_set_schematic_component_property and
_handle_remove_schematic_component_property registered in the
command dispatch table
Tests (tests/test_schematic_component_properties.py):
32 tests covering escape helper, paren matcher, add/update/remove
(single + batched), full spec dicts, default position, default
(hide yes), special-character escaping, UUID preservation, protected
built-in field rejection, no-op removal, both new convenience tools,
and input validation. All 590 tests in the project still pass.

Adds two new MCP tools for working with free-form text annotations
(SCH_TEXT elements) in KiCad schematics:
- add_schematic_text: place a text note with optional angle, font size,
bold/italic, and justification
- list_schematic_texts: list all text annotations with optional
case-insensitive substring filter
Includes WireManager.add_text / list_texts using _text_insert + sexpdata,
handler dispatch in KiCADInterface, TypeScript tool definitions, registry
entry, reference doc updates, and 30 unit tests.

export_netlist was returning "Unknown command" because no Python handler
existed. generate_netlist was timing out (30s) due to an O(nets × components
× pins) wire-graph algorithm with a new PinLocator instantiated per net.
Both handlers now delegate to `kicad-cli sch export netlist`:
- export_netlist: new handler; writes KiCad XML / Spice / Cadstar / OrcadPCB2
to the caller-supplied outputPath. Added schematicPath parameter to the TS
tool definition (was absent, making file export impossible).
- generate_netlist: replaces the slow wire-graph with kicad-cli + XML parse;
returns the same {components, nets} JSON the TS handler already expected.
Also adds _find_kicad_cli_static() so both handlers share CLI discovery
without depending on ExportCommands (which requires a loaded pcbnew board).
Cleaned up generate_netlist schema in tool_schemas.py (removed outputPath and
format fields the handler never used), updated MCP tool descriptions and
SCHEMATIC_TOOLS_REFERENCE.md to clearly distinguish the two tools.
26 unit tests added covering parameter validation, subprocess mocking,
format mapping, XML→JSON parsing, and error/timeout propagation.

Four tools added in this branch had no docs coverage. Add entries to
SCHEMATIC_TOOLS_REFERENCE.md with parameter tables, response field
tables, and usage notes. Update section tool counts (Net Analysis 4→5,
Validation 3→6).

- add_schematic_net_label: document new optional componentRef/pinNumber
snap-to-pin mode, labelType/orientation params, response fields
(actual_position, snapped_to_pin), and updated position to optional
- connect_to_net: document new response fields (pin_location,
label_location, wire_stub)
- get_schematic_pin_locations: update cross-reference to reflect that
direct pin snapping is now available in add_schematic_net_label

Add Prettier as a dev dependency with .prettierrc.json config and
.prettierignore. Hook added via mirrors-prettier in pre-commit config.
All TypeScript, JSON, Markdown, and YAML files auto-formatted.
