add vdi2230 skill: VDI 2230 bolt joint dimensioning engine
Full R0-R13 calculation engine with:
- Guided data collection (N bolts, per-bolt load, DA_prime, thermal dT)
- Auto-sizing script (M4->M39 iteration across strength classes)
- fm_table A1 lookup for fast MA/FM queries without full R0-R13
- Warnings for stainless steel galling, ESV insert threads (Helicoil/Ensat)
- Bolt circle load distribution formula (FA + MB + MT)
- 7 evals covering static, fatigue, ESV aluminium, pressure seal,
thermal steel-aluminium, and combined FA+FQ cases
