Introduces an engineering/ package that lets MCP clients produce production- quality technical drawings without LLM-improvised geometry. Adds 7 new MCP tools, an 8-step pre-completion validator, and an automatic linetype + layer bootstrap on drawing_new so CENTER/HIDDEN/PHANTOM and standard mechanical layers (GEOMETRY, DIM, HATCH, TEXT, TITLEBLOCK, ...) are always available. - engineering/gear.py: pure-Python involute math, 40+ points/flank, helical + spur front views, deterministic section A-A (no helix lines in section). - engineering/keyway.py: DIN 6885 keyway table + parametric keyed bore / side-section drawers. - engineering/titleblock.py: ISO 7200 A3 (420x297 mm) title block; title text is written verbatim to the title cell. - engineering/validator.py: DrawingValidator with 8 checks (real DIMENSION entities, no hidden orphans, linetypes loaded, bore + keyway in both views when expected, title consistency e.g. forbid 'HELICAL SPUR GEAR' when helix_angle truthy, saved-to-disk + file-on-disk, screenshot exported, dwg path returned). - backends/ezdxf_backend.py: AutoCAD-only linetype fallback (HIDDEN, BORDER families) so ezdxf doc gets correct patterns when linetype_load is called for names ezdxf.tools.standards does not ship. - backends/base.py: concrete helpers set_layer_active / ensure_linetypes. - server.py: Section 12 with 7 engineering tools, drawing_new(bootstrap= True), and an ENGINEERING WORKFLOW block in the MCP instructions string. - 30 new tests covering gear math, DIN6885 lookup, ISO A3 layout, title verbatim, and every validator check. Tool count 89 -> 96.
