fix: project-local library resolution + copy_routing_pattern geometric fallback + TypeScript tool

- fix: DynamicSymbolLoader reads project sym-lib-table before global dirs
  add_schematic_component now finds symbols from project-local .kicad_sym files
  project_path derived automatically from schematic file path

- fix: place_component reloads FootprintLibraryManager with project_path
  new boardPath parameter passed to place_component tool (TypeScript + Python)
  _handle_place_component wrapper recreates LibraryManager per project

- fix: copy_routing_pattern geometric fallback when pads have no nets
  primary filter: net-based (when pads are assigned to nets)
  fallback: bounding box of source footprint pads +5mm tolerance
  filterMethod field in response indicates which mode was used

- feat: register copy_routing_pattern as MCP tool in routing.ts
  sourceRefs, targetRefs, includeVias, traceWidth parameters

Live tested: ESP32 + 2x TMC2209 in Test3 project
  13 traces U2 routed, copy_routing_pattern copied all 13 to U3
  offset Y+30mm correct, 26 total traces verified
