chore(deps): update all dependencies to latest stable

Rust:
- sysinfo 0.38 -> 0.39 (now requires rustc 1.95)
- bollard 0.20 -> 0.21
- refresh Cargo.lock for compatible transitive updates
- add rust-version = "1.95" to reflect raised MSRV

Frontend (all semver-minor/patch, no breaking majors available):
- react/react-dom 19.2.6, vite 8.0.13, vitest 4.1.6, eslint 10.4.0,
  tailwindcss/@tailwindcss/vite 4.3.0, lucide-react 1.16.0, and others
- npm audit fix resolved 5 transitive advisories (fast-uri, hono,
  ip-address, express-rate-limit) with no breaking changes

MSRV raised 1.75 -> 1.95 (sysinfo 0.39 requirement); README updated.
No source changes required; all Rust + frontend gates green.
