refactor: modernize tooling, tests and metadata

[trueberryless-bot]

Brings the site in line with the shared setup from template-files. The design is untouched.

Changes

• Dependencies: Astro 7.3.5, @atproto/lex 0.3.13, @lucide/astro 1.48, sharp 0.35.5, Prettier 3.9.9, prettier-plugin-astro 1.1, fontless 0.4 → 1.2 (the fonts still build), TypeScript 6 (not 7), pnpm 11.28.0, Node 24+ and "type": "module". pnpm build succeeds.
• package.json: name, bugs and repository still pointed to trueberryless-org/trueberryless. They now use felixs.dev and trueberryless/felixs.dev from the shared template.
• Type check: added astro check (pnpm check). The four errors it found are fixed: fragmentLabel could call .replace on undefined, SkillChips typed its map key as nullable, and the project Card did not accept null descriptions or language. astro/tsconfigs/strictest reports 105 more errors (mostly indexed access), so I kept strict and dropped the unused React JSX settings.
• Branding: the standard OG image (felixs-dev preset, 👋) and its emoji as favicon.svg, plus og:site_name and the image size and alt text.
• Accessibility: the decorative year watermark on the blog is now aria-hidden.
• Tooling: oxlint, Prettier (oxfmt does not support .astro), knip, and the shared workflows, .gitignore, .prettierignore and LICENSE. Removed the unused exports that knip found.
• Tests, run in CI: 18 Vitest tests for cache.ts, posts.ts and buildReadingSummary (100 % coverage of cache.ts and posts.ts), and 34 Playwright tests on desktop and mobile against the built node server: headings and titles of every page, the 404 page, canonical and OG metadata, no horizontal overflow, and axe checks in both color schemes.

Not covered

• data.ts (863 lines of GitHub and ATproto fetching) has no tests and is excluded from coverage. The end-to-end tests only assert what does not depend on that data, because the server islands fetch it at request time. Mocking that layer is a good follow-up.
• oxlint still reports 3 no-map-spread warnings.
• The README badge used trueberryless.org for the page speed check. It now uses felixs.dev.

Verified

astro check, oxlint, Prettier, knip, vitest --coverage and the 34 Playwright tests pass locally.
