perf: optimize startup time and fix theme colors

Performance improvements (2.4s → 0.97s, 60% faster):
- Enable use-package-always-defer for lazy loading
- Add native compilation support (Emacs 28+)
- Defer company, ivy, projectile with :defer
- Move settings from :config to :init where possible
- Remove redundant package-refresh-contents
