Replace Astro/Strapi site with Next.js static export

- Fresh structure: Next.js App Router + Tailwind v4 at the repo root, exported
  as static files (output: export) and served by static-web-server
- Remove the Strapi CMS, Astro app, Pagefind search, comments, old scripts,
  Lighthouse config and compose files; content in content/ is now plain
  markdown with YAML frontmatter
- Pages: About, Writing, Reading (3D bookshelf) and Portfolio, styled after
  adammaj.com
- SEO: metadata and canonicals, JSON-LD, generated OG images, sitemap, robots,
  RSS and JSON feeds, llms.txt
- Umami via PUBLIC_UMAMI_SCRIPT_URL / PUBLIC_UMAMI_WEBSITE_ID (build args)
- Dockerfile builds the export and serves it with sws.toml (security headers,
  clean URLs, .well-known, OG image content type, immutable asset caching)
- Prettier and cspell for content with a husky/lint-staged pre-commit hook
- Old redirect list dropped to start from a clean slate

-spend my free time working on hobby projects and sometimes I write about my experiences. In particular, I enjoy learning about offensive security and reverse engineering.

+## Some things about me:
+
+- I'm a software engineer by day. Cyber Security is my hobby and my side work.
+- I have a degree in computer science, and most of what I do for fun still centres on it.
+- I'm the captain of the [**binarysith**](https://ctftime.org/team/379200) CTF team. I play CTFs on the weekends under the alias **mockingspectre**.
+- I like infrastructure-level software: the code that other code runs on.
+- I write essays on software development, from personal experience to opinion pieces (with varying degrees of "success"). The blog has been going since 2021 and has moved around a lot: different domains, Medium, dev.to, Hashnode. This site is where I keep the originals.
+
+## Some things I'm interested in:
+
+- The intersection of software engineering and cyber security.
+- Low-level programming, because it's where performance and security meet.
+- Distributed systems and performance at scale.
+- Compiler design.
+- Database internals.
+- Reading, fiction and non-fiction alike, especially the classics.
+- Art, history and science.
+
+Check out my [reading](/reading), [writing](/writing) and [portfolio](/portfolio).
