📚 Sync project-specs.md and package.json with current state

project-specs.md:
- Replace Prettier/ESLint/Vite/Vitest references with oxfmt/oxlint/oxc
  and TypeScript 7 / node --test
- Drop @tsconfig/strictest note; rules are inlined in tsconfig.json,
  enumerated explicitly
- Document oxlint rule disables (no-undefined, sort-keys, id-length,
  no-named-export) and test-file overrides (no-unused-expressions,
  no-empty-file, no-nodejs-modules, no-magic-numbers)
- Document Node 26 / .node-version / engines.node / CI follow
- Document allowImportingTsExtensions + rewriteRelativeImportExtensions
  for the node --strip-types quirk
- Replace Vite/vitest coverage example with c8 + node --test
- Sync scripts section: drop check:eslint, check:prettier and their
  fix:* counterparts; add check:oxlint/check:oxfmt/fix:oxlint/fix:oxfmt
- Add current source layout (index.ts, match.ts, pattern.ts, index.test.ts)
- Update VSCode integration section with actual settings.json and
  extensions.json contents
- Document the actual commit history with gitmoji prefixes
- Fix 'initilizing' typo
- Drop 'changesets is a devDep' claims (changesets is not installed)

package.json:
- Move @oxfmt/binding-* and @oxlint/binding-* from devDependencies to
  optionalDependencies so the right binding is selected per platform
  (CI on Ubuntu gnu gets the gnu binding automatically, not the
  local musl one)
- Extend check:outdated to ignore the platform-specific bindings (they
  show as 'not installed' on the current platform, which is correct
- Add cspell words: gitmoji, dbaeumer, msvc (the latter for the Windows
  binding variant). Drop the unused 'nocheck' word

README.md:
- Drop the 'changesets is available as a devDep' line; changesets
  isn't installed
