feat(tooling): migrate from ESLint + Biome to oxlint + oxfmt

Replace ESLint and Biome with oxlint and oxfmt, matching the
PSYLOCKE-GG config. Convert all biome-ignore directives to
oxlint-disable equivalents, remove noDefaultExport suppressions
(not needed), fix interface→type, and update CI workflow.

 ## Design Context
 
 ### Users
+
 A mixed audience of potential clients (gaming/Minecraft industry), employers, fellow developers, and the broader community. Visitors are evaluating Stella's work, personality, and technical ability. They want to quickly understand what she does, see compelling examples, and get a sense of who she is as a person.
 
 ### Brand Personality
+
 **Warm, approachable, fun.** The site should feel like meeting someone genuinely enthusiastic about their craft. Not corporate, not cold — personality shines through in every detail. Think: a friend showing you their coolest work over coffee.
 
 ### Aesthetic Direction
+
 - **Visual tone:** Portfolio showcase — image-heavy, visual storytelling, project cards that invite exploration
 - **Typography:** Instrument Serif for headings (editorial warmth), Switzer for body (clean readability)
 - **Color:** Purple primary (#9145FF) is the brand identity. Blue (#0085FF) and yellow (#FAC230) as playful accents. Both light and dark themes supported.
