fix: P134 set_material verifies (zh/en names), run_macro binds swApp/Part and reports where it stopped

[raylanlin]

What Changed

v0.2.133 (P134). This fixes three problems seen in a real session: the part was built correctly, but its material was never applied, and the agent then spent about ten calls on macros that silently did nothing.

• set_material
  • Before: it reported success while nothing was applied. SetMaterialPropertyName2 returns nothing and silently ignores unknown names; a Chinese install has 「合金钢」, not "Alloy Steel".
  • Now: it tries each candidate (the given name, then its zh/en alias, in both database spellings) and verifies each by reading the density back.
  • If nothing takes: that is an error. An unchanged density on a part that already had a material returns verified:false instead of claiming success.
• run_macro: nothing was bound
  • The tool promised that swApp and Part were bound, but nothing assigned them.
  • The entry Sub now binds swApp / Part / swModel when the macro uses them.
• run_macro: runtime errors reported as success
  • A runtime error in the entry Sub still came back as "脚本执行完成".
  • Fix: the entry Sub is now instrumented:
    • Before each statement it records the line number and text. It skips continuation lines and the line just after Select Case.
    • A completion flag is set at the end of the Sub and on every Exit Sub.
  • Result: a macro that did not reach its end fails and names the line it stopped on.
• Connection note: attached to the first result only, and it now distinguishes three cases: SolidWorks not running, a background instance shown, a second instance started.

Type of Change

• 🐛 Bug fix
• ✨ New feature
• 📝 Documentation
• ♻️ Refactor
• 🧪 Tests
• 🔧 Build / CI

Testing

• npm test passes (201 tests). New vba-macro-writer tests cover binding, the completion flag, line reporting, and no marker where VBScript forbids a statement.
• npm run lint passes. typecheck, ruff, pytest (67 tests) and compileall also pass. New set_material tests cover the zh fallback, an error when nothing takes, and the ambiguous case.
• Manual test on Windows + SolidWorks (the generated VBScript cannot be executed on the Linux CI):
  • set steel and read the mass
  • a run_macro that reads Part.GetTitle
  • a deliberately broken macro, which should fail and name its line

Checklist

• Code follows project conventions
• Self-reviewed
• Docs updated (if needed)
