feat: slot op liniaal/geodriehoek en richtingsbewust langs de lat tekenen (v0.3.76-beta)

- Slot-knop (🔓/🔒) op liniaal én geodriehoek: vastgezet gereedschap kan niet meer verschuiven of draaien (draaiknop verdwijnt), er kan alleen nog langs getekend worden; tweede klik ontgrendelt
- Naast de lat beslist nu de richting i.p.v. één vaste afstand: binnen 22px van een rand wacht de haal de eerste ~7px beweging af - loopt die grofweg evenwijdig aan de rand (≤30°), dan kleeft hij, anders blijft hij vrij; een tik zet gewoon een stip
- Daarmee is langs de lat tekenen betrouwbaar (ook met dikke digibord-vingers) zónder dat de lat vrije halen in de buurt grijpt
- Op de lat zelf blijft de intentie ondubbelzinnig: direct kleven binnen 24px van de rand
- Geverifieerd in headless Chromium: 12 nieuwe checks (richtingsregel, stip-tik, slot aan/uit, vastgezet = onverplaatsbaar maar betekenbaar) + de drie bestaande suites (35 checks) blijven groen
