docs(wiki): align wiki structure with Aetoskia AGENTS.md guidelines

- Renamed `02_architecture.md` to `02_components.md` to match the standard component page naming convention.
- Updated `docs/mkdocs.wiki.yml` to reflect renamed pages and fix navigation label acronym casing (GSDFC, MCP, MkDocs).
- Updated `index.md` to include the mandatory doc model blockquote, standardize section headers with emojis, and accurately map the `Documentation Structure` table to the navigation menu.
- Standardized all wiki pages (`01_overview.md`, `02_components.md`, `03_conventions.md`, `04_iterative_workflow.md`, and `05_development/*`) by:
  - Adding horizontal rules (`---`) between major sections.
  - Applying emoji-prefixed H2 headings for recognizable section types.
  - Appending `## Related` or `## ➡️ Read Next` footers with standard relative cross-links.
  - Adjusting H1 headers to match guide anatomy (e.g., `# Library Overview` on the overview page).
