feat: terminal-noir redesign — widget system + design token overhaul

Replace cyan-green modern theme with terminal-noir aesthetic aligned to
style-guide.md. Hard edges, monospace-first, linear transitions, no gradients.

Introduce Widget component as the single repeatable section primitive:
title bar with horizontal rule, optional badge/meta — all pages and
sections now use this pattern (Glance-inspired data-driven layout).

Design system changes (globals.css):
- Palette: #0a0a0a bg, #111111 surface, #00cc44 status green, #cc2200 alert red
- Drop Montserrat; Source Code Pro primary, system sans for prose only
- Transitions: linear 120ms; no eased animations, no border-radius

Component changes:
- Nav: flat, border-bottom only, lowercase links
- Hero: 56px square photo, status dot, @ email glyph
- ProjectCard: flat bordered card, 2-col grid, no gradient tile
- Skills: key-value rows with dot-separated values
- Footer: minimal text links

Pages: all sections wrapped in Widget; homelab uses gap-px grid for
at-a-glance, services, and ADRs sections. Archive uses flat list layout.

Data: remove gradient field from Project type; add optional year field
