docs: add 18 ESLint-style rule example pages (#90)

* docs: remove hardcoded versions and counts, point to source files

CLAUDE.md: replace command table, ADR list, and pinned versions with
references to src/commands/, .archgate/adrs/, and .prototools.
README.md: remove commands table and CI section, defer to docs site.
Homepage (en + pt-br): replace "Six ADRs" with open-ended text and
link to the ADRs directory on GitHub.

* docs: add 18 individual ESLint-style rule example pages

Restructure the rule examples documentation:

- Split inline examples out of writing-rules.mdx into dedicated pages
- Convert common-rule-patterns.mdx into a categorized index page
- Add 18 individual rule pages (EN + PT-BR = 36 files) covering:
  dependency management, import restrictions, file structure,
  code quality, database schema, and architecture boundaries
- Each page follows ESLint-style format: rule details, incorrect/correct
  code examples, full .rules.ts implementation, when to use/not use
- Use Starlight autogenerate for the Examples sidebar section
- Real-world examples sourced from archgate, money-sync, and
  stavanger-challenge repositories

* docs: regenerate llms-full.txt
