chore: release 7.5.1

[vakovalskii]

Summary

Patch bump from 7.5.0 → 7.5.1.

What's in 7.5.1

• Neuraldeep visual identity (feat(design): port neuraldeep visual identity (palette + Inter + motion) #225) — new dark palette (#08090C bg + neon #00FF88 accent), Inter font, 180ms theme cross-fade, accent-pulse keyframe, prefers-reduced-motion respected. Monokai theme preserved untouched
• Pi / Oh My Pi resume-target hardening (fix(pi): harden resume target handling #224) — non-Pi Resume buttons no longer routed through Pi-specific helper, /api/launch only forwards resumeTarget for Pi sessions, scope tightened to what was actually needed

Verified

• node --test test/*.test.js → 146/0/2 (no regressions)
• CI matrix expected to be green 6/6
• Dark / Light / Monokai themes confirmed visually via Playwright

After merge

GitHub Release v7.5.1 → workflow publishes to npm automatically (granular token + bypass 2FA already configured).
